The skull of the English Carrier (c) compared with other types of pigeon. Charles Darwin wrote of the Carrier in The Variation of Animals and Plants Under Domestication, "This is a fine bird, of large size, close feathered, generally dark–coloured, with an elongated neck". [5]
A 2017 study of passenger-pigeon DNA found that the passenger-pigeon population size was stable for 20,000 years prior to its 19th-century decline and subsequent extinction, while a 2016 study of ancient Native American DNA found that the Native American population went through a period of rapid expansion, increasing 60-fold, starting about 13 ...

There are many fancy or ornamental breeds of pigeons: among them are the English carrier pigeons, a variety of pigeon with prominent wattles and an almost vertical stance, the Duchess breed, which has as a prominent characteristic feet that are completely covered by a sort of fan of feathers, the fantails with a fan of tail feathers like a ...
Modern-day homing pigeons do have English carrier blood in them because they are in part descendants of the old-style carriers. [citation needed] The domestic pigeon is derived from the wild rock dove (Columba livia sspp.); the rock dove has an innate homing ability, [7] meaning that it will generally return to its nest using magnetoreception.

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 .
The Variation of Animals and Plants Under Domestication went on sale on 30 January 1868, thirteen years after Darwin had begun his experiments on breeding and stewing the bones of pigeons. He was feeling deflated, and concerned about how these large volumes would be received, writing "if I try to read a few pages I feel fairly nauseated ...
Estimating the population size of pigeons is necessary for monitoring and control programs of pigeons in parks and other urban areas. The methods used for estimating populations sizes are: Stratified grids: This method consists in dividing the area where pigeons occur in 500x500m squares. 34% of the squares are selected randomly and pigeons are ...
