Columba flavirostris Wagler, 1831 |
The Red-billed Pigeon, Patagioenas flavirostris (see Johnson et al. 2001), is a relatively large pigeon which breeds from southern Texas, United States, and northwestern Mexico south to Costa Rica. It belongs to a clade of Patagioenas which generally lack iridescent display plumage, except some vestiges in the Pale-vented Pigeon.
It is found in open country with some trees, large clearings and cultivation in lowlands and middle altitudes to 2100 meters. It builds a rudimentary platform nest out of twigs in a tree about 4-25 meters above the ground, usually on a horizontal branch or on a palm crown, and lays one white egg.
The Red-billed Pigeon is 30 centimeters long and weighs 230 grams. It is mainly wine-purple, becoming browner on the back, and with a grey tail, lower belly and flight feathers. The bill is white with a red base, and the legs and eyes are red. Juvenile birds are duller than adults and the plumage is brown-tinged.
It is normally seen alone or in pairs and rarely forms flocks. It feeds on the ground, seeking acorns, berries and buds.
The Red-billed Pigeon has a loud kuk c'c'coooo call that is given in rows; the initial short kuk is characteristic for this group of Patagioenas (Mahler & Tubaro 2001).
