Among birds, Cole and his students focused on the genetics and hybridization of Columbidae, particularly domestic pigeons and ring doves. Along with papers considering plumage color, the team published work on the genetics of the birds' immunology , fertility, and physical defects.
A Spread Ash Pomeranian show crest pigeon, showing one of the forms of feather crest that pigeons may possess. From a genetic perspective, there are two loose ancestral clades of pigeons, but there is striking genetic homogeneity due to frequent interbreeding and human directed cross-breeding; pigeon fanciers often do not enforce breed ...
Pigeon keeping or pigeon fancying is the art and science of breeding domestic pigeons. People have practiced pigeon keeping for at least 5,000 years [ 1 ] and in almost every part of the world. In that time, humans have substantially altered the morphology and the behaviour of the domesticated descendants of the rock dove to suit their needs ...
The Gaditano Pouter is a breed of fancy pigeon developed over many years of selective breeding. [1] Gaditano Pouters, along with other varieties of domesticated pigeons , are all descendants of the rock dove ( Columba livia ).
It is unknown why the Birmingham Roller and other roller pigeons tumble. While it is true that the birds do perform backward somersaults in flight, the exact neurological causes of the rolling behaviour are still unknown. This bird has a genetic inclination to flip backwards, provided adequate training, diet, and exercise.
This is an alphabetical list of pigeon breeds; these are exclusively breeds of the domestic pigeon (Columba livia domestica). Other Columbidae species (e.g., the Barbary dove , Streptopelia risoria ) have been domesticated and developed into breeds, but these are generally simple colour variations of the plumage .
Utility pigeons are domesticated pigeons bred to be a source of meat called squab. Squabs have been used as a food in many nations for centuries. [1] They were bred to breed and grow quickly. [2] Because they are bred for squab production, conformation to a show standard is usually deemed unimportant.
Feral pigeons often only have small populations within cities relative to the number of humans. For example, the breeding population of feral pigeons in Sheffield, England in summer 2005 was estimated at 12,130 individuals (95% confidence interval 7757–18,970), in a city with a human population of about 500,000.
