Darwin devotes pages to domesticated pigeons
in Origin as well as in other writings, such as Variation, and returns again and again to examples from pigeon breeds to support other related points.
14) Falcons are commonly infected directly with APMV-1 through feeding on infected domesticated pigeons
(Columba livid), coturnix quail (Coturnix japonica), and, more rarely, poultry, or indirectly by being housed in close proximity to infected birds or by fomites.
Scientists don't yet know whether the mutation arose in a wild ancestor of domesticated pigeons
or if it sprang up only after domestication.
The research identified the genes contributing to variation in the avian head crest, using the domesticated pigeons
that so fascinated and inspired Charles Darwin in developing his theory of natural selection," said George Gilchrist, program director in the National Science Foundation's (NSF) Division of Environmental Biology, which funded the research.
The birds you see loafing on city buildings or farm silos are not direct descendants of wild rock doves; their immediate ancestors were domesticated pigeons
bred for a variety of colors, patterns and body shapes.
The role of domestic geese as a WN virus reservoir in the Israel outbreak is unknown, but goose infection rates in the Sindbis District of the northern Nile Valley were 27%, similar to rates in buffed-back herons (Bubulcus ibis ibis), doves (Streptopelia senegalensis senegalensis), and domesticated pigeons
(Columbia livia) and twice the rate in domesticated chickens and ducks (Anus platyrhynchos), suggesting that geese may have a role in local WN virus ecology (7).
