La paloma de collar (Patagioenas fasciata)​ es un ave de tamaño mediano de América.


Se encuentra desde la Columbia Británica, Utah y el sur de Colorado en las elevaciones más altas a través de México y América Central hasta el norte de Argentina. En otoño migra fuera de la parte de su distribución al norte de California, Nuevo México y el oeste de Texas. Las poblaciones del sur de Costa Rica a veces es considerada una especie separada, P. albilinea. Se encuentra en altitudes de 900 a 3600 m, generalmente en rodales de encino, pino-encino y bosques de coníferas. Se alimenta de semillas, sobre todo bellotas.

Band-tailed pigeon

The band-tailed pigeon (Patagioenas fasciata) is a medium-sized bird of the Americas. Its closest relatives are the Chilean pigeon, passenger pigeon and the ring-tailed pigeon, which form a clade of Patagioenas with a terminal tail band and iridescent plumage on their necks. There are at least 8 sub-species, and some authorities split this species into the northern band-tailed pigeon (Patagioenas fasciata)and the southern band-tailed pigeon (Patagioenas albilinea).

It ranges from British Columbia, Washington, Oregon, California, and southern Arizona south in higher elevations through Mexico and Central America to northern Argentina. In autumn it migrates out of its permanent resident range into northern California, New Mexico, and parts of Utah and Colorado. It is found from almost sea level to 3,600 m (12,000 ft), generally in oak, pine-oak, and coniferous forests. It feeds on seeds, notably acorns, as well as berries and small fruits.


It is the biggest pigeon in North America, measuring 33 to 40 cm (13 to 16 in) long and weighing 225–515 g (7.9–18.2 oz). The coastal subspecies P. f. monilis (averaging 392 g (13.8 oz)) is larger than the inland subspecies (averaging 340 g (12 oz)). The plumage is gray, somewhat darker above. The head and underparts have a faint pink cast, especially in the adult male; the belly is nearly white. The distal half of the tail is also pale (except in the subspecies of Baja California), whence the English name. The bill and feet are yellow, good identification marks at sufficiently close range. Adults have green iridescence on the back of the neck, adjacent to a thin white collar on the nape. Juvenile birds have white feather edges above, giving a scaly appearance.

Behavior and ecology

This species is relatively quiet for a pigeon. Its voice is low-pitched and owl-like, often in two-syllable calls that rise and then fall (huu-ooh) with even spacing between calls.

It builds a rudimentary platform nest out of twigs, in which it lays one or two eggs. Outside the breeding season it forms flocks, sometimes over 50 birds, and often becomes nomadic, following the acorn crop or moving to lower altitudes or other areas outside its breeding range. They commonly congregate at and drink from mineral springs, although it is not fully understood why. In addition to acorns and other seeds, the band-tailed pigeon will seasonally consume fruits such as Pacific madrona and Toyon berries. This species often visits bird feeders.

The parasitic louse Columbicola extinctus, believed to have become extinct with the extinction of the passenger pigeon, was recently rediscovered on the band-tailed pigeon. The band-tailed pigeon is the closest genetic relative of the passenger pigeon and has been investigated for being used in efforts to bring back that extinct species.
