Northern Foul Mite


 CONTRIBUTED BY DR. CHARLES BACON

The Northern Fowl Mite: 
I have read and have talked over this past year about the problem with a mysterious mite      that infect the Kings, and in some instances kill an adult bird.  From the descriptions presented to me during these events, and what I have read, I believe this is the action of the Northern Fowl Mite.  Some king breeders have made some written comments on the problem but I do not recall an identity of the suspect agent.  The Northern Fowl Mite (Ornithonyssus sylviarum) is an 8-legged white, grayish, black or deep red tiny mite that consists of many stages of development ranging from pearly white eggs, to larva (a non-feeding 6 legged translucent whitish variant), a nymph (another 8-legged organism like the adult whose color ranges from grayish to deep red, depending upon the amount of blood is has consumed.   The time from egg to adult is only 7 days.  Both the adult and nymphs do the most damage, and they differ from the usual chicken mite in being always present on the bird, even during the day.  The usual chicken mite hides during the day and get on the birds at night.  Further, the Northern Fowl Mite can only survive off the host for a limited number of days, perhaps as long as 3 weeks.  The usual chicken mite can survive several months without a bird and without feeding.  On pigeons and other birds the Northern Fowl Mite is found in large numbers and congregate at the vent, tail, back and neck.  In pigeons they are found in large numbers at the vent and between the legs.  The eggs are laid in the fluff of feathers, especially vent feather fluff, which when viewed appear at it a fungus (mycelium) is attached to the feather at the shaft enters the bird’s flesh.  The eggs as at first white then vary from white to gray and also appear blackish, and in such numbers (well over 5,000) that the lower half of each feather shaft appear fuzzy and can be mistaken for fungi.  Within a period of 8-10 weeks, some 20,000 mites can be found on birds and at this level of infestation the bird is considerably weakened.  As a result of such server infestations the birds suffer from severe anemia and finally death.  Death may occur either from blood loss or from an impaired immune system.  Other side effects are weight loss, a peculiar feeding habit (feed picking is hampered), pale eye cere, black scabs on the skin, which may enlarge into a very large area of the abdomen, reduce egg laying in flocks, and heavy infection prevents the ability of cocks to mate.  Caution:  these mites can and do infect humans producing severe skin irritations.

            The recommended control ranges from garlic oil to chemical pesticides.  My favorite is permectin, which is absolutely harmless to the bird but immediately kills mites or insects as well and remains as a residual kill for at least 4 weeks.  There have been other recommendations using a mixture of pesticides which I know should work.  I believe the reaction from some for such harsh treatment is due to an assumption that the feather-egg combination is still observed and some believe this material is not dead, but the data says they are dead. It takes time for these eggs/larvae to detach and fall off the birds.  However, you always run the risk of re-infestations for these, as they and the regular chicken mite can crawl off and re-infest the bird, especially with some pesticide that do not have a residual kill as permectin.  Hope this helps.

                                 A DISCUSSION-JUDGING THE SHOW KING 


Note-The following article by Mr. W. B. Schroeder was delivered in the form of an address at the Fourth Annual American Pigeon Fanciers Convention held July 28-29 1973 at St Louis Mo. And printed in the American Pigeon Journal December 1973.

 

     Properly applying the American King Club Standard of Perfection for exhibition Kings, to Kings in the judging theater, requires a thorough knowledge of this Standard and the understanding that a good show King must be a balanced pigeon; having the station, conformation, weight, measurements, appearance, show manners, and points of perfection described in the official Standard.  The degree to which each individual King, in the judging theater, has these desired qualities determines its placing position in the class being judged.

     There are no points allocated in the official Standard of perfection for station and conformation but the Standard does say that the official picture is the ideal for the station of the exhibition King.  Neither does the official Standard list points for weights and measurements although it does say that the weights must be adhered to.  The Standard also says that the cocks should be masculine in appearance and that hens should be feminine in appearance and that birds of unkempt appearance, or birds that refuse to show good station or proper show manners may be cut up to 10 points in a floating penalty that is not considered in the 100 point total of the Scale of Points.  All of which means that a King in the judging theater must have the general appearance of the king shown in the official picture; and must approximate the weight, measurement, and appearance of the exhibition King, as set forth in the written preamble to the Scale of Points in the Official King Standard of the American King Club, if it is to receive serious consideration for top placing in its class.

     Station can be defined as the desired position of the bird when in its proper stance.  Conformation can be defined as the form of the King resulting from the symmetrical arrangement of all items of perfection described in the official Standard.  Balance is a state of equal relationship of station, conformation, weight, measurement, appearance, and the items of perfection described in the Scale of Points of the official King Standard.

     With an official Standard that sets out the desired station, conformation, weight, measurement, and appearance of the exhibition King, without giving point credit for these items of perfection, per se, it becomes apparent that an ideal King is a balanced King scoring high in all items of perfection rather than in points listed in the Scale of Points of the official Standard.  Therefore, a judge should not attempt to total points in his mind, of the various items of perfection listed under the Scale of points of the official Standard, for each individual King being judged, but instead, should use these points to determine the degree of perfection of each item listed in the Scale of Points as he compares one King against another.

     A judge should begin his assignment by looking at each individual King in the class to determine how closely it resembles the station and conformation of an exhibition King as it is shown in the official picture of the exhibition King that has been adopted by the membership of the American King Club.

     When looking at the profile view of a King a judge should see legs that are straight, and show no sign of cow hock*, and that are balanced in the center of the body at a point where a vertical line would run at a right angle from the floor up to the center of the legs to a point at the top of the neck where it begins at the back of the head.  The breast should curve down from the front of the neck in a full curve to the front of the legs with that curve picking up the rump behind the legs, at the same level and continuing in a smooth line, showing no fluff, until it reaches the tail which at its tip is 15 degrees* above the horizontal level of the back.  The wing flights should be reasonably short and rest smoothly on the rump and tail with the tips held approximately one-inch apart and approximately three-fourth of an inch shorter than a reasonably short tail.  The wings should be deep with the body showing well below the wing butts.  The neck should be full and balanced with broad shoulders and well rounded body and it should be carried perpendicularly.  The neck should not cut back excessively under the beak and the beak should recede slightly from the extremity of the protruding breast and be carried in a horizontal position; and be short, stout, and pinkish white in color.  The head should be moderately large with a well-rounded skull that is in proportion to a full neck and a broad body.  The eyes should be prominent, round and bright and set approximately three-fifths forward from the back of the skull at a point where a line running up from the center of the beak would intersect through the center of the pupil of the eye.  The eye cere should be perfectly round, fine in texture, and not over one-sixteenth inch wide, visible between eye and the feathers, and be beet red in color.

     The front view of the King should show a broad skull, and a prominent breast that is broad and well rounded and shows well beyond the wing butts.  The legs should be stout and straight, with greater width than height, and set at a width of two and seven-eighths inches from the center of one shank to the center of the other and showing two and five-eighths inches clearance between the floor and the bottom of the keel.  The legs should be free from feathers and beet re in color.  The toes should be straight, clean, well spread, and beet red in color. 

     The top view of the king should show a broad skull, a short, stout, beak; pinkish white in color, with a wattle in keeping with the size of the face and being small, smooth, powdered or frosted in color.  The back should short, wide at the shoulders, and taper smoothly into a broad and thick rump and on to a tail not over two feathers wide at the tip*. The wing flights should rest flat on the rump and tail and show no sideboards and there should be no break or hinge in the rump.

     When a judge takes a King into his hands to get the top view of the bird he should also get the feel of the bird and make a preliminary judging determination by segregating the King into one of three groups, namely, group number one for Kings that look and feel as the official Standard describes an ideal King to be.  Group number two for Kings that show the station and conformation desired in an ideal King but lack the feel of a good King, and Kings that have the proper feel but lack the desired station and conformation. Group number three for Kings that neither show the station and conformation of an ideal King nor have the feel of an ideal king.

     A King that feels good in the hands of a judge is one that has a short, broad, firm, deep, well-rounded body, with a short back that is broad at the shoulders and tapers into a full rump, and that has a rocker shaped keel that is straight and deep and ends as close as possible to the vent, with a full breast, and with feathering that is close and smooth.  A King with this feel can score a maximum of 45 points, of the 100 points listed in the Scale of Points of the Official King Standard, for perfect body, back, keel, breast, and plumage.  With head and neck elements of items in the Official King Standard receiving maximum total of 30 points, and all other parts of an ideal King 25 points, the King with good feel must be given preliminary priority consideration in judging for the same reason station is given that consideration: the Official King Standard places the most emphasis on these two items of perfection by picturing the ideal station of a King and by crediting a maximum number of points to those items that go towards the good feel of the bird.  Kings that have a good feel are usually birds that feel larger than they look to be.

     It is in the preliminary judging that a judge gives full consideration to the point credit of the 15 items listed in the Scale of Points of the Official King Standard.  He does this as he handles the bird for the first time and places those that total the highest number of points into group one or two, depending on their station, conformation, weight, measurements, and appearance: as these items are set out and described in the preamble to the Scale of Points in the official Standard.  After the preliminary judging has been completed, with all Kings having been segregated into one of three groups, the judge uses the point credits for the various items listed under the Scale of Points of the official Standard to help him determine the degree of perfection of each item which is established by the number of elements of that item that meet the description of the official Standard.

     After each King has been handled and placed into one of the three groups enumerated above the elimination process begins in group three with the judge discarding the least desirable King in that group first, and then the second least desirable King when judged in accordance with the official Standard of perfection, and continuing in this manner on through that group into group two and through group two and then through group one until all Kings have been placed down to the last bird in the class which is then the first place King.  While working through group three a judge will sometimes find a bird showing excellent station that it was not showing the first time he looked at it and this bird might then be judged against birds in group two and go on to place higher in the class than some of those Kings originally placed in group two.  When working through group two it is always good practice for a judge to be slow to eliminate a King from further competition that has exceptionally good feel.  This bird may not be showing when the judge first looks at it because of fright, which may come form rough or unfamiliar handling in being transported from the holding pen to the judging pen or from having been cooped in a lower tier in a dark corner of the showroom before being brought out into the bright light of the judging arena, and after it grows accustomed to the new surroundings it begins to show station and will hold that station for the balance of the judging.  When the judge reaches a point in his judging where he feels he should eliminate from further competition a King that is outstanding in feel, but lacks proper station, he should move forward to grade the rest of the Kings in group two by lining them up in proper order in their judging cages. He should then go forward into group one and follow the same procedure of grading Kings and lining them up in proper order in their judging cages.  He should then come back to group two and if the King with outstanding feel is still not showing proper station it should be eliminated from the class because no matter how good the body and feel may be it is not a good King if it has not by this time shown proper station as portrayed in the official picture of the exhibition king.  We sometimes hear exhibitors say that they had a King place high in its class at one show and then had it eliminated early in the class at a second show.  When this happens, assuming the judge of the first show placed the King properly, and the quality of the competition was the same, it results from one or two things: Either the bird was not in the same body and feather condition at the second show or the judge eliminated it too quickly from the class and before he had given it a fair chance to show.

     A King is not necessarily a good exhibition King because it has outstanding body and feel, or because it has breath-taking station, or superior leg setting, or a beautiful head and neck.  To be a good show King it must score high in all the items listed in the official Standard of perfection in a manner that blends them together to create a bird of perfect beauty.

     There are 15 items listed in the Scale of Points of the Official King Standard and each of these items is made up of a number of elements with each element receiving equal credit toward the total points listed for the particular item of perfection.  These 15 items added to the 6 items set out in the preamble to the Scale of Points give the judge a total of 21 items to consider as he compares one King against another in the elimination process.  Which means that the King that is best in 11 or more of the 21 items would eliminate the bird against which it is compared and go on to be compared against another King where the same method of determination would be used to eliminate one of the Kings from further competition in the judging.  By following this procedure down through the class the judge determines the relative excellence of each King and winds up with the best balanced bird in the class as his first place bird.

     A judge starts the elimination process by comparing the birds in group number three, picking what appears to be the poorest King in that group and placing it in the end coop of the judging theater, and then comparing it against what appears to be the next poorest King and continuing on in that fashion to line the birds up in their proper order in the judging coops with the poorest King in the end coop and the second poorest King in the next to the end coop and continuing this order of placement down through the group but not eliminating any of them from competition until all Kings in that group have been compared.  When this has been done the judge returns to the end coop in which he has placed the poorest King in the class, and the elimination process then goes quite quickly as the birds have been lined up in their proper order and it now becomes a matter of the judge checking his original judgment of each King to be sure it was correct.  If he finds it was not correct he moves the bird or birds up through the class until he finds their correct position and then goes back to the bottom of the group to continue the elimination process.  When the judge gets down to the last bird in group three he compares it with birds in group two and it then becomes a part of that group until eliminated from further competition.  He follows the same procedure of comparing Kings in group two and lining them up in their proper order and then going back over the group to eliminate birds from further competition until he is down to the last bird in group two which then becomes a part of group one.  The Kings in group one are then compared for the number of items of perfection they possess and are lined up in the judging coops accordingly. The judge then goes through this group of birds from the poorest to the best, checking on his original judgment as he proceeds with the elimination process, to find the best balanced King having the greatest number of items of perfection as those items are described in the official Standard.

     In comparing one King against another the judge should first of all determine which of the two Kings has the best station and then continue by determining which of the two kings has the best conformation, whether the Kings fall within the weight limits, whether they answer the measurements, which King is masculine or feminine in appearance, and which King has proper show manners.  A King with proper show manners will be alert, yet unafraid, and will be well poised, showing no sign of fear or aggressiveness as the judge reaches into the coop to pick it up.  After the judge has compared the two Kings on the items of the perfection listed in the preamble to the Scale of Points of the Official Standard, he proceeds by comparing the first item listed in the Scale of Points which is the beak.  He determines if the beak of the two Kings he is comparing against one another are short, stout, pinkish white in color, and carried in a horizontal position: as the official Standard says they should be, or if these beaks are long, narrow, stained, and down faced.  If the beak meets the description of the Standard it will receive 5 points or 1 and ¼ points for each of the four elements that go to make up a perfect beak. And it will be cut 1 and ¼ points for each element of the beak that does not fit the Standard description.  The King having the beak coming closest to what the Standard calls for will be the beak having the greatest number of elements of perfection.  The judge then compares item number two in the Scale of Points, which is the wattle.  He examines the wattle on the beak to determine if it is small in keeping with the size of the face, smooth, and powdered or frosted in color.  If it meets with this description it receives a credit of 3 points.  If it lacks any of these elements it would receive a one-point cut for each lacking element.  The judge follows by comparing the head, eyes, eye cere, neck, breast, body, keel, back, wings, tail, shanks, toes, and plumage of the kings, keeping in mind the number of elements that go to make up the number of points listed in the Scale of Points for each of the above named items, and then crediting or cutting items on each King in accordance with the manner in which the elements answer or fail to answer the official Standard description.  

     The judge will not try to remember the point totals of the items of perfection of the Kings he compares against one another, but, instead, will remember which of the two Kings scored highest in a majority of the items of perfection to help him select the best balanced bird of the two.  He then eliminates the King with the fewest items of perfection from further competition and goes on to compare the other King with another bird in the class, eliminating the poorest of these two Kings from further competition as determined by their number of items of perfection, and continuing on with this practice until he has eliminated all but one bird in the class which is the top placing and first place bird in the class.

     With an Official King Standard that sets out 6 desired items of perfection without giving them point credit and then lists 15 items of perfection which do receive point credit. It becomes obvious that a good exhibition King is a well-balanced bird that scores high in all desired items of perfection rather than being outstanding in some and poor in others.

     Judging Kings, if done properly, is hard work and it requires an intense concentration of the eyes and mind of the judge to the point where he does not see or hear anything in the showroom other than the birds he is judging. A judge should be thoroughly familiar with the wording of the Standard and have a mental image of what an ideal King should look like as he goes into the judging arena to pass on the birds.  He should be well rested as he begins his judging assignment as intense concentration can be tiring and a tired judge will not be as observing as he otherwise can be and this could cause him to misplace birds in judging competition.  Judges sometimes travel hundreds of miles to fulfill an assignment and traveling can be tiring, and sleeping in a hotel or motel can be anything but restful, so a judge must be in good physical condition and mentally alert if he is to do his job properly. 

     A judge must not visit with exhibitors or talk to individuals, other than show officials, while he is performing his judging duties.  He should not attempt to explain each of his decisions to exhibitors and spectators watching the judging as this often involves him in a discussion and becomes too time consuming in large classes of Kings and it serves little purpose as most exhibitors today are as knowledgeable as the judge is on what constitutes a good show King and they are usually only interested in reasons for his decisions on the top placing birds in each class.  The judge may tell his Steward, in a few brief words, as he hands him a bird being eliminated from further competition, why that bird is being eliminated and the Steward can pass that information along to the bird carrier for the benefit of any interested party.  Doing this makes it possible for a spectator to know why a bird was eliminated and it serves the purpose of educating the Steward, who may be interested in becoming a judge, in judging procedure.  In classes where the competition is exceptionally good the judge may explain why he has picked the first place bird over the second place bird and the second place bird over the third, but to go beyond that takes more time than the judge usually has available to him and it may unduly tire the judge to the point he is not as effective as he should be on the balance of the classes to be judged.  An exhibitor who has a question concerning a particular decision or bird can always see the judge after he has finished his judging assignment and will usually find the judge more than willing to talk to him.

     A judge should never break faith with those fanciers who have honored him, in selecting him to judge their birds, by drinking any form of intoxicating beverage while carrying out his judging assignment even though he is invited to do so by the exhibitors.  Doing so may not affect his judgment but it will certainly lesson the respect that some exhibitors have for him.

     Most judges make a personal sacrifice of time and money when they judge a pigeon show and the only rewarding compensation for judging any pigeon show comes out of the personal satisfaction of knowing you have done a good job in placing the Kings in their proper positions in each class.  Do not jeopardize that personal satisfaction by reporting for a judging assignment in anything other than a well-rested physical condition and an alert mental condition.  Do not get involved in time consuming and judgment distracting conversations with exhibitors or spectators and, above all, do not say or do anything that could reflect on your personal integrity.  Keep faith with those who have honored you, and who have devoted much time and effort in breeding, conditioning, and training the Kings you have been assigned to judge, by selecting the best birds in each class as the first place birds and by picking a Champion that on that particular day and at that particular time was truly the Champion of the show.

                     Artificial Insemination


Artificial Insemination of Pigeons and Doves

By Ray D. Owen, Dep't of Genetics

University of Wisconsin, Madison, WI (Reprinted from Poultry Science 20: 428-431, 1941)

Since the development by Quinn and Burrows (1936) of a simple method of obtaining semen from and inseminating gallinaceous (chicken-like) birds, artificial insemination has made possible a number of studies on the physiology of reproduction and hybridization of these birds. An extension of the technique to the smaller birds, particularly to the pigeons and doves, holds promise as a tool for more extended work along the same lines.

The pigeons and doves include a wide variety of species, many of them separated by psychological and size barriers preventing normal copulation. Barriers of this sort can be surmounted by artificial insemination. In their physiology of reproduction, these birds offer the same problems as those already studied by means of the insemination technique in gallinaceous birds, and in addition problems concerned with the specific and regular ovarian cycle not encountered in the Galena. Furthermore, certain types of pigeons (for example, featherless, rumpless) cannot copulate normally, and artificial insemination provides a possibility of reproducing these types.

Bonadonna (1939) includes male pigeons, finches, and canaries in a list of birds, which have been ejaculated successfully in his laboratory by the "American method of pressing the semen from the bulbous ducts." He does not describe any modification in detail necessitated by the extension of the technique from large to small birds, and he does not record successful insemination of these small birds. His method of obtaining semen is undoubtedly the same as that to be described in this paper. It may nevertheless be considered worthwhile to place on record the details of the technique in its extension to small birds, and to describe a successful method of insemination in these species.

I. Obtaining semen:

The technique to be described is essentially that of Burrows and Quinn, modified in those details which are affected by the differences between large and small birds. The beginner will find it advantageous to work at first with relatively tame male pigeons of fairly large size. Later, when the technique is acquired, wild, (and) small birds can be trained to ejaculate. It is usually wise to keep males to be used for ejaculation in separate cages. Males kept together in large pens, or even males which are mated, can often be ejaculated regularly; in general, however, the yield of semen from these males is small.

A male to be ejaculated is held in the left hand, with his head toward the operator's left. The hand is extended along the bird's back with the fingers towards the tail and with the little finger hooked under the front of the right wing. The thumb and index finger are pressed against the opposite sides of the dorsal (top) surface of the pygostyle (the tail end of the vertebral column - the fleshy swelling to which the tail feathers are attached).

The thumb and second finger of the right hand are pressed behind the tail and against the sides of the base of the cloacal projection, while the third finger of the right hand is pressed deeply between the pubic bones, immediately below the vent. If the position of the fingers is correct, by pressing the hands toward each other the vent can be made to appear, not as horizontal slit or as a small round hole, but as a wide opening in which the two ventral fleshy folds of the cloaca are exposed.

The tail of the bird is now made to spread and fold alternately by a rhythmic pinching pressure of the thumb and index

2

finger of the left hand on the dorsal surface of the pygostyle. With the same rhythm, the fingers of the right hand "milk" the cloacal area. The vigor of the massage necessary varies with the male in use; some males require a quick, rough pressure while others yield better to slower, more gentle treatment. The manipulation should begin as soon as possible after the bird is caught, since delay decreases the probability of success. It will be found helpful to pluck clean of feathers, an area an inch or so in diameter around the vent, a day or two before attempting to obtain semen.

A small, truncated cone into which the head, wings, and thorax, can be pushed has been found useful in holding large pigeons and small doves. The technique of the massage is not changed when the birds are held in this fashion. Usually after a second or two of massage a small drop of clean milk-white semen will appear on the ventral (lower) surface of the cloaca. The yield of semen can frequently be increased by continuing the stripping motion for a second or two after the first semen appears. Meanwhile, the thumb and forefinger of the left hand, which have been operating on the dorsal surface of the pygostyle, are slipped around the pygostyle and pressed deeply against the sides of the vent, holding the vent open and the drop of semen where it is easily seen and reached.

This frees the right hand for the operation of an eyedropper, which can be used to collect the semen. In pigeons the quantity of semen averages from 0.01 to 0.02 cc per collection; the average collection contains about five to six million sperm. In domestic pigeons, the quantity of semen does not appear to vary as a function of size of bird. Among species, however, smaller species are consistent in producing smaller quantities of semen per ejaculate. Most male pigeons can be ejaculated several times a day; if semen is collected from a male regularly more than once a day, however, that bird often become
aspermic (without sperm).

Occasionally, a male is found to be so susceptible to manual stimulation that after a brief massage, the fleshy folds of his cloaca erect and the bird goes through the twitching motion of copulation, the erected folds being thrown well beyond the margin of the vent to form a pointed copulatory organ. Ordinarily, however, the male is quite passive and exhibits no copulatory reflex. Males of the latter sort require somewhat longer massage than do the more susceptible ones. If semen does not appear after 15 seconds of massage of any male he may as well be returned to his cage and tried again after an interval of not less than 15 minutes, with some variation in the technique or vigor of massage. In no case has a male pigeon or dove ejaculated with sufficient force to cause the drop of semen to lose its contact with the organ.

Occasional contamination of the semen with urine or feces may be expected, particularly with untrained males. Frequently ciliates (microscopic organisms) appear upon microscopic examination of the apparently clean ejaculate. Granted the presence of large numbers of motile spermatozoa, however, these ciliates do not appear to affect fertility. Blood cells, probably the result of rupture of capillaries (tiny blood vessels) in the wall of the cloaca, are also occasionally found in the ejaculate.

II. Inseminating

The semen collected can be introduced with the eyedropper directly into the oviduct of a laying female. It is neither necessary nor usually feasible to protrude the oviduct of the female as is commonly done with hens, turkeys, and guineas. The oviduct opens on the left side of the cloaca; by probing the eye- dropper to the left and somewhat dorsally, the opening of the oviduct can be discovered, the pipette pushed gently an inch or so into the oviduct, and the semen deposited there. While undiluted semen is effective in insemination, dilution of the collection with a drop or two of warm bird saline or Ringer's solution has proved

3

productive of a greater percentage of fertile clutches.

Female pigeons and doves do not ordinarily lay when they are isolated. Two methods have been successful in surmounting this obstacle; the first, which is most easily accomplished, is least efficient in its use of cage space. If a male and a female of the same species are put in adjacent cages where they can see and hear each other well (and there seems to be added stimulus to the female if the male can touch her through the bars or mesh of the partition), the female will usually lay regularly.

The
second method requires more attention. Two females placed in the same cage will often lay regularly. However, in this case the cycles of the two females soon approach coincidence, and in order to establish the maternity of the eggs, the birds must be separated the day before the first egg of each is laid. A third method, which has not yet been tried, but which might be an improvement, would be to mate females for insemination with vasectomized males.

Usually a female stimulated to lay by any of the methods mentioned above will incubate her eggs and rear the squabs. In the interest of more efficient use of females for insemination studies, however, it is often advisable to remove clutches as soon as they are complete. Eggs to be used for fertility determination or embryonic study may be transferred to an incubator and incubated until the desired stage is reached. Eggs which are to be hatched and the squabs raised may be transferred to foster parents.

It is, of course necessary that the foster parents be in the proper stage of their reproductive cycle, so that when the fostered young hatch they will be fed and cared for by parents whose crop glands are prepared to provide nourishment of the correct sort for the young. In order to insure this, the foster parents should be scheduled for hatching within a day or two of the date on which the fostered eggs are due to hatch.

Fertility has been obtained from a single insemination as much as eight days and as little as one day before the first egg of a clutch was laid. In the latter case, only the second egg of the clutch was fertile. Our experiments indicate that the period included from the third to the sixth day before laying of the first egg is the period during which a single insemination is most likely to produce fertility. Multiple inseminations (for instance, inseminations on the third, fourth, and fifth days before the first egg of the clutch is laid) practically insure fertility in most intra-specific matings. The regularity of the ovarian cycle in pigeons and doves makes it possible to predict within narrow limits the date upon which an egg will be laid.

The amount of semen required to produce fertility in pigeons and doves is considerably less than that recommended in gallinaceous birds. Thus, while Burrows and Quinn (1939) indicate that 0.1 cc of semen injected once a week will produce 80-95 percent fertility in most chicken matings, 0.01 c.c. diluted to 0.03 c.c. with warm bird saline has produced fertile clutches in 62 percent of our trials with pigeons when the insemination occurred on the third to the sixth day before the first egg of the clutch appeared.

             INHERITANCE OF COLOR IN PIGEONS BY GARY SMITH



The King pigeon hobby has three (3) base colors; ash red, blue/black (black is spread blue), and brown in that order of dominance and the dilution of each color.  Three patterns; check, bar, and barless in that order of dominance (I am not aware of any barless kings).  We also have spread birds (solid colors).  Spread hides the true pattern of the bird, it is still either a check or bar patterned bird.  We also have white’s; white is not a color, it is the absence of color;  the bird is still either ash red, blue/back, or brown and has a pattern; either check or bar.  In order to get spread colored offspring, at least one of the parents must be spread (white and recessive red are not true spread, so it is not necessary to have a spread parent to get a white or recessive red young).

 

Symbols I use to identify my birds:

Color               check pattern                               bar pattern                   spread

Ash Red           ash red check (ARC)           ash red bar (ARB)      spread ash (SA)

Ash Yellow      ash yellow check(AYC)    ash yellow bar(AYB)  spread ash yellow(SAY)

 

Blue/                blue check (BKC)               blue bar (BB)

Black               black check (BKC)                                                 black (BLK)

True Silver/       true silver check(TSC)       true silver bar (TSB)

Dun                                                                                                  dun (DUN)

 

Brown              brown check (SC)                silver bar (SB)              brown (BRN)

Khaki              khaki check (KC)                 khaki bar (KB)            khaki (KH)

 

Indigo               =          /I                      example: ARC/I

Grizzle              =          /GZL                                ARC/GZL

Opal                 =          /Op                                  BLK/Op

Faded              =          /f                                      BKC/f

Reduced           =          /r                                      BB/r

Pale                  =          /p                                     BRN/p

Recessive red   =          RR                                   RR

Recessive Yellow  =     RY                                   RY

Recessive Gold     =    RG                                    RG

White               =          WHT                               WHT

Any other color =         /AOC                               ARC/AOC                                                                                         

  

   Then we have factors;  indigo, opal, grizzle, faded, reduced, toy stencil, milky, pale, and recessive red to mention a few.  These factors distort or change the appearance of the true color of the bird, which must be one of the three main colors.  Outcrosses from other breeds can produce almond/magnani colored birds, however our three main colors are it for most Kings.  I see in our June bulletin the Cajun King Club is having a RARE Futurity to include Almonds with the 3rd and 4th District Show in November.  All I really

know about Almond/Magnani is that it is dominate to all our standard King colors.  So I  assume that all 1st generation offspring would be almond and the cocks would carry a 2nd color of one of our standard King colors.

 

   When speaking in terms of our base colors, keep in mind that the cock bird may have

and often does have a second color, the one you see and the one he may carry.  The same

is true for a white or recessive red cock, except you will not see either color.  Yes, you can indeed have a white or recessive red cock (for example) hides a first color of ash red,

and a second color of black or brown.  These colors will express themselves when the bird is mated to a non white or non recessive red.  The cock birds color (the one you see) will always be the color of most dominance, so you will never get a brown cock that carries black or ash red, nor will you get a black cock that carries ash red.  The hen does not carry a second color nor dilution, but may carry a second pattern (check carrying bar).  The cock may carry a second pattern and carry dilution.

 

Order of dominance:

Intense color                  Dilution                                Symbols for chart

1st  Ash red                  Ash yellow                               AR         AY

2nd  Blue/Black True Silver/Dun                        B/B         TS/Dun

3rd  Brown                    Khaki                                       BRN       Kh

 

     If the cock carries dilution, he should produce half the hens dilute of his two colors when mated to an intense hen.  A dilute cock on an intense hen will have 100% dilute hens, and 100% intense cocks ,  which all carry dilution.  A mating of an intense cock and a dilute hen will produce 100% intense young, but all the cocks will carry dilution.  A mating of an intense cock that carries dilution to a dilute hen will produce both intense and dilute young of either sex.  Mating a dilute cock to a dilute hen produces 100% dilute young.

 

*   =    Cock carries dilution.

Scenarios of intense/dilution matings:

Cock                      Hen                                          Young expectations

1.   Intense                   Intense             =                      100% of young intense

2.   Intense*                 Intense             =                      C- 100% intense, 50% *

                                                                                    H- 50% intense,   50% dilute

3.   Intense                   Dilute               =                      C- 100% intense*,   H- 100% intense

4.   Intense*                 Dilute               =                      C- 50% intense*,   50% dilute

                                                                                    H- 50% intense,   50% dilute

5.   Dilute                     Intense             =                      C- 100% intense*,   H-100% dilute

6.   Dilute                     Dilute               =                      100% of young dilute

 

   When the cock throws either his first or second color recessive to the hens color, or the hens color is recessive to either of the cocks two colors,  all baby cocks second color will be that of the recessive color……….Example;  AR cock carries B/B mated to a BRN hen…if the young cock is AR or B/B he will carry BRN, because BRN is recessive

to both of his color options.  The cock will contribute one color gene for the young, the hen may or may not contribute a color gene.  When she does the young will be cocks, when she doesn’t the young will be hens.  So a cock has  (+ +) two colors genes, and a hen has (+ -) one color gene.  Any time the hen throws the blank (-), the young will be a hen because it has only one color.  If the cock has two colors the same, then he is known as being homozygous in color, meaning he has no second color, or is pure in color.

   Any time you mate a cock to a hen of a color with higher dominance, it is a sex linked mating and the baby hens will be one of the colors of their father, and the baby cocks will be the color of their mother.  It is also a sex linked mating to put a dilute cock on an intense hen, because dilution is recessive to intense.  The baby cocks will be  intense and all hens will be dilute.  This does not apply to patterns;  check is always dominate to bar.             Although the color charts above should be accurate in 99% of all pairings, I will say that seven (7) times in 16 years Mother Nature has produced ash red young in my loft out of pairs that were B/B  x  BRN combinations………….all turned out to be hens……….this is not supposed to happen!   It is important to understand that when it comes to Mother Nature and pigeon colors, “there are no absolutes. “

Northern Fowl Mites

Northern fowl mites are the most common and are the most economically important among poultry mites. Northern fowl mites infect chickens, turkey and game birds. They also cause considerable infestations in pheasants. The northern fowl mite is a serious pest concern in all areas of the United States and throughout temperate zones of other countries. It can be mistaken for the red chicken mite, but unlike the red mite, it can be found on birds during the daytime as well as night. The northern fowl mite has been reported as being seen on many species of birds and may be carried by the English sparrow. This parasite is most commonly seen in caged layer facilities and on range turkeys.

Northern fowl mites feeding on poultry. From: "Common Lice and Mites of Poultry: Identification and Treatment." ©U.C. Regents. For the complete publication, go to link: http://ucanr.org/anrcatalog.poultrymites.
Northern fowl mites are blood feeders causing anemia in birds that are highly infested. Anemia reduces a bird's efficiency, production and ability to withstand and overcome other diseases. Meat birds infected with northern fowl mites will have reduced value due to blemishing by scabby areas on the skin. Infected laying flocks will experience a fall off in egg production. Infestations exceeding 200,000 mites will produce fatal conditions due to anemia and its interference with the bird's immune response. Birds stressed by mites will lose weight, have pink combs, and their feathers are generally soiled with mite excrement. Feathers around the vent area also become soiled. Due to the tendency of mites to congregate around the vent, they can also reduce a rooster's ability to mate successfully.
The life cycle of the northern fowl mite requires less than one week. Eggs are laid along the shafts of feathers and hatch within 24 hours. The entire life cycle is spent on the host with growth from egg to maturity completing in about four days. Infestations of northern fowl mites may dwindle during the summer months, but are more severe during winter weather.
Total control of the northern fowl mite requires the use of chemical pesticides. Mites are more resistant to pesticides than lice, so treatment may require a rotation of pesticides used. Pesticides for treating infestations of the northern fowl mite must be applied directly to the bird as a wettable powder, emulsion concentrated spray or as a dust. Effective treatment for small, floor-reared flocks can include the application of a dust - treating the bird, litter and providing dust boxes for the birds to dust bathe.

Legendary King breeder John Schroeder enjoying a new lease on life…at 84

 

By Larry Foos, AKC publicity director

 

Nestled in an inland hillside community of San Diego, the home of Master Show King Breeder John Schroeder has produced more champion white kings than any one person will probably ever equal. But John has seemingly retired from the competition, and his home is not so much regulated by what he keeps in the back lofts, but it’s more about just hanging out and taking it easy. It’s a home he helped build and where he and his wife, Betty, have resided for more than 40 years.

 

Living just a few miles due South, I asked John if he would oblige to an interview and update everyone some of things going on in his life. He agreed, and on Saturday, May 2, I came over, sat in his living room and had this conversation with him.

 

Larry: How’s your health? And your wife?

John: I’m doing pretty good. I’m not quite as strong as I use to be. I’m 84 years old, so that means a lot. Betty’s in good health. She’s a little younger than I. She’s 80 now.

 

Larry: Did you think in 2009 you’d still be raising pigeons?

John: No I didn’t. You know, after my trip to the hospital and all the birds were gone I thought that was it for me. But when I came home, I missed them so much that I had to have a few more to keep in the backyard.

 

Larry: How long have you been raising pigeons?

John: I had Kings since 1963. I grew up with (pigeons). I had them since I was about 5 years old—just common pigeons. I grew up in Texas—mostly in the area of Waco. I got to San Diego because of the Navy.

 

Larry: You think you’ll ever show again or judge again?

John: No, I’m out of that category. I just keep my own in my backyard and get visitors from overseas just about every year, two or three of them. And sometimes I sell them a few.

 

Larry: You’ve had a big track record of Nationals you won—how many and which was the most gratifying?

John: I won 23 Nationals. And I think the one most gratifying was in Houston, Texas. Bill Haudrich was judge. And the bird was #898, young white hen. I still know the number (laugh). It was in 1973. That was my first one. There probably was 500-600 Kings there. I won Nationals with up to 700 birds exhibiting.

 

Larry: You got in an accident in 2007. What happen?

John: Well, I was cleaning the loft and as I went out the door, I caught my heal in the door. It had those springs on them. And I fell on my buttocks. I got up, finished the cleaning and everything. A few hours later it started bothering me and I went to a chiropractor. He gave me a treatment. The next day I couldn’t walk. Both legs were paralyzed! I went to the hospital to run tests. They said the problem was the sciatic nerve but both legs were affected. Don’t really know. My wife couldn’t care for me—you know I’m too heavy and I was in a wheel chair. So I was in a convalescent home. In there 29 days…the worse 29 days of my life! My grandson and wife told Ron Zych to pick up the pigeons. I couldn’t take care of them. He picked up everything.

 

Larry: I remember you had an empty loft and in October, 2007 I brought all my birds to your house because we were being evacuated due to fires. I remember coming over for those few days every day and you seem to be enjoying them again.

John: Yes, that’s right. I realized I could raise them again. Just for my own enjoyment.

 

Larry: Do you have a different outlook now raising pigeons?

John: Yeah, it gives me self-satisfaction. I go out in the morning, or whenever I feel like and I look at the birds and I just enjoy them you know. I don’t need to show them to enjoy them. And I compare them with one another, which is the good ones, so forth and so on.

 

Larry: I remember you telling me that (last year) was one you enjoyed raising Kings more than a long time.

John: I would say so. I enjoyed it more and this is 2009 and I’m enjoying it now. And I’m a lot stronger than I was before (at time of the accident). Of course you don’t know at my age how long you’ll stay strong (laugh).

 

Larry: So you think raising pigeons had a big part of your recuperating?

John: Absolutely.

Larry: Your mental health and well being?

John: Absolutely.
