This pied Toy Stencil blue bar (U-6273 / 1057-C)  is unique - having both wildtype (blue-black) and brown (b) coloration in its plumage.  It is extremely black but not spread (S).  Its rectrices (tail feathers) are white, brown and wildtype.  It is the offspring of a heterozygous brown (+//b) cock and a brown (b/.) hen.  It became very sick and had to be culled before any offspring were produced.  It was believed to be a female; but there is a possibility of mis-identification of the birds sex.  However, if it were a male it is equally unique.  It was under six months of age when culled.

One of twenty six (26), penciled x gazzi, F2's, all of which displayed much white in their plumage.  None were without white (unpied or self colored), or even approaching a near unpied plumage.  This data supports what has been suspected for years, i.e., that gazzi (z), recessive white (z^wh), and penciled (pc) are alleles.  More date is needed.

The expression of nasal-tuft in pigeons vary from a neat tuft behind the wattle, at the base of the upper mandible, to several feather whorls on the head.  This ash-red checker has additional small whorls over each eye.  Sideburns (Sb) produces similar whorls, but in the homozygous state (Sb//Sb) birds display a pronounced abnormal head waving action.  Identifying a homozygous nasal-tuft (Nt//Nt) may be difficult.  It may prove allelic to sideburns?

Pigeon x Dove Hybrid

Photo taken in September 1991.

Given to me as a gift, this male hybrid entered a pigeon fanciers loft in nearby Missouri.  Clearly, it appears as a pigeon x ring-necked dove hybrid; but the parent birds were unknown.  He was paired to more than one female ring-necked dove and produced many infertile eggs.  It died unexpectedly.  Photo by Ron Mangile
