White-crowned Pigeon
Encyclopedia
The White-crowned Pigeon (Patagioenas leucocephala, formerly Columba
leucocephala) is a species of bird in the family Columbidae (dove
s and pigeons). It inhabits the northern and central Caribbean
islands and some places on the North
and Central America
n mainland. John James Audubon
painted the pigeons, including the watercolour in his work Birds of America
, published in the early 19th century.
It is 29 centimetres (11.4 in), has a wingspan of 48 centimetres (18.9 in), and weighs 0.15 kilogram (0.330693393277316 lb). The adult is dark grey, with green and white bars on the nape, a brilliant white crown to the head, a white iris, and a pale-tipped red bill. Juveniles are a less dark shade of grey, lack the nape pattern and white iris, and show only a few pale feathers on the crown. The song is row of a Mourning Dove
-like woo pop woooo calls; this species is a member of a diverse clade
of Patagioenas which vary much in appearance, but are united by their triple coos (except in the Scaled Pigeon
).
It is a resident breeder mainly in the Bahamas
, Cuba
, Jamaica
and Antigua
. It breeds in smaller numbers in Hispaniola
, Puerto Rico
, the Virgin Islands
, the Cayman Islands
, Anguilla
and other Caribbean
islands. It also breeds along the Caribbean coast of Central America
. In the United States
it is found only in the Florida Keys
and the southern tip of mainland Florida
.
The main threat to this species is hunting. In Florida a major cause of mortality is collision with man-made objects.
Another main threat to this species is loss of habitat. The White-crowned Pigeon needs two distinct habitats, one for nesting and one for feeding. They typically breed in coastal red mangroves (Rhizophora mangle
), which continue to be clear-cut for crops such as sugarcane
. Agriculture and deforestation have become a problem for the species' feeding grounds, typically inland hardwood forests. The bird is very skittish, and is known to simply abandon its nest when it is encroached upon.
