The pale-vented pigeon (Patagioenas cayennensis) is a large pigeon (family Columbidae) found in the tropical American. Formerly often placed in Columba, it actually belongs to a clade of the older New World genus Patagioenas. With its relatives it represents an evolutionary radiation extending through most of the warm-temperate to tropical Americas. Grey-hued birds, even their males generally lack iridescent display plumage, although the present species has some coppery gloss on the nape.
It is a resident breeder from southern Mexico south to Bolivia and northern Argentina and on Tobago and Trinidad, although it is very localised on the latter island. Vagrants are occasionally seen in adjacent regions; for example, the species is noted to stray into Uruguay from Argentina and occasionally from Brazil, but it has never been noted to breed or even maintain a permanent presence in the former country.
The pale-vented pigeon is 30–32 cm long and weighs normally 230–250 g. Adult males have a mainly dull purple head, breast and upperpart plumage, with copper glossing on the nape and a whitish throat. The lower back and tail are dark grey and the lower underparts are pale grey. The bill is black and the legs, iris and eyering are red. The female is similar, but duller than the male, and immatures are greyish-brown, very dull, and mainly greyish brown.
The southern subspecies P. c. andersoni has white lower underparts, rather than the pale grey of nominate P. c. cayennensis.
