The white-crowned pigeon (Patagioenas leucocephala) is a fruit and seed-eating species of bird in the dove and pigeon family Columbidae. It is found primarily in the Caribbean.
John James Audubon painted these pigeons, including the watercolour painting in his work, Birds of America , published in the early 19th century.
In the first half of the 18th century the white-crowned pigeon was described and illustrated by several naturalists including John Ray in 1713, [3] Hans Sloane in 1725 [4] and Mark Catesby in 1731. [5] When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the white-crowned pigeon with all the other pigeons in the genus Columba . Linnaeus included a brief description, coined the binomial name Columba leucocephala and cited the earlier authors. [6] The specific epithet combines the Ancient Greek leukos meaning "white" and -kephalos meaning "-headed". [7] Although Linnaeus gave the location as North America, the type locality is taken to be the Bahamas following Catesby. [8] The species is now placed in the genus Patagioenas that was introduced by the German naturalist Ludwig Reichenbach in 1853 with the white-crowned pigeon as the type species. [9] [10] The species is monotypic: no subspecies are recognised. [10]
The white-crowned pigeon can measure 29–35 cm (11–14 in) in length, span 48–59 cm (19–23 in) across the wings, and weigh 150–301 g (5.3–10.6 oz). It is around the same size as the common rock pigeon, but weighs a bit less since it is generally less chunky and has a relatively longer and more square tail. [11] Adult birds' plumage varies from a slate gray to an almost-black color. Its iridescent collar-patch is notably only seen under good lighting, shining a barred white pattern with green. Their distinct crown-patch can vary in shade of color from a more bright white in males to a more gray-white in most females. [12] Juveniles can have a grayish-brown color for They have 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. Their call is a loud, deep coo-cura-coo or coo-croo. 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). [13] [14]
It is a resident breeder mainly in the Bahamas, Cuba, Jamaica and Antigua. It breeds in smaller numbers in Hispaniola (the Dominican Republic and Haiti), 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, Everglades, and the southern tip of mainland Florida. [15] They will often spend the winter in the Caribbean islands.
The white-crowned pigeon primarily lives and breeds in nest colonies or individually in low lying, coastal, mangrove forests, and will travel inland to feed on the fruits and seeds of a wide variety of plants. In Florida, the white-crowned pigeon has historically been documented nesting exclusively on remote, tidally inundated mangrove islands in wildlife refuges. Recent observations have confirmed nesting on the southern tip of mainland Florida. [16]
With few exceptions, this species requires isolated offshore mangrove islets with limited disturbance for breeding. [15] These tidally inundated mangrove islands which provide some protection from predators such as raccoons. However, several instances of white-crowned pigeons nesting in heavily trafficked, urban areas, such as downtown Key West and Miami Florida, have recently been observed. This could be due to habitat loss as a result of hurricanes, and/or increased predation pressure in their historic nesting habitat. [16]
A main threat to this species is loss of habitat due to deforestation and habitat degradation. 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. In Florida, white-crowned pigeons often feed on the fruit of poisonwood ( Metopium toxiferum ). Unfortunately, this native plant causes severe human dermatitis and is often removed.
The white-crowned pigeon is also hunted, often illegally, throughout much of its range. Although, changes have been made to hunting regulations in the Bahamas, illegal hunting is still a problem for these pigeons.
Other threats to this species include (in Florida) a major cause of mortality is collision with man-made objects; and pesticide use. [15]
Like the extinct passenger pigeon, this species illustrates a very important principle of conservation biology: it is not always necessary to kill the last pair of a species to force it to extinction. These birds are "threatened by the slaughter of nesting birds on its Caribbean breeding grounds"; they may play a vitally important, yet not fully understood, role in the seed dispersal of West Indian flora. [17]
The stock dove or stock pigeon is a species of bird in the family Columbidae, the doves and pigeons. It is widely distributed in the western Palearctic.
The common wood pigeon, also known as simply wood pigeon, is a large species in the dove and pigeon family (Columbidae), native to the western Palearctic. It belongs to the genus Columba, which includes closely related species such as the rock dove. It has historically been known as the ring dove, and is locally known in southwest England as the quist, or in southeast England as the "culver"; the latter name has given rise to several areas known for keeping pigeons to be named after it, such as Culver Down and Culver Hole in South Wales. It has a flexible diet, predominantly feeding on vegetable matter, including cereal crops, leading to them being regarded as an agricultural pest. Wood pigeons are extensively hunted over large parts of their range, but this does not seem to have a great impact on their population.
The red-headed woodpecker is a mid-sized woodpecker found in temperate North America. Its breeding habitat is open country across southern Canada and the east-central United States. It is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered species, having been down-listed from near threatened in 2018.
The red-bellied woodpecker is a medium-sized woodpecker of the family Picidae. It breeds mainly in the eastern United States, ranging as far south as Florida and as far north as Canada. Though it has a vivid orange-red crown and nape it is not to be confused with the red-headed woodpecker, a separate species of woodpecker in the same genus with an entirely red head and neck that sports a solid black back and white belly. The red-bellied earns its name from the pale reddish blush of its lower underside.
The purple finch is a bird in the finch family, Fringillidae. It breeds in the northern United States, southern Canada, and the west coast of North America.
The eastern meadowlark is a medium-sized blackbird, very similar in appearance to sister species western meadowlark. It occurs from eastern North America to northern South America, where it is also most widespread in the east. The Chihuahuan meadowlark was formerly considered to be conspecific with the eastern meadowlark.
The mourning dove is a member of the dove family, Columbidae. The bird is also known as the American mourning dove, the rain dove, colloquially as the turtle dove, and it was once known as the Carolina pigeon and Carolina turtledove. It is one of the most abundant and widespread of all North American birds and a popular gamebird, with more than 20 million birds shot annually in the U.S., both for sport and meat. Its ability to sustain its population under such pressure is due to its prolific breeding; in warm areas, one pair may raise up to six broods of two young each in a single year. The wings make an unusual whistling sound upon take-off and landing, a form of sonation. The bird is a strong flier, capable of speeds up to 88 km/h (55 mph).
The bird genus Columba comprises a group of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. Columba species – at least those of Columba sensu stricto – are generally termed "pigeons", and in many cases wood-pigeons. The rock dove, has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon.
The emerald dove or common emerald dove, also called Asian emerald dove and grey-capped emerald dove, is a widespread resident breeding pigeon native to the tropical and subtropical parts of the Indian Subcontinent and Southeast Asia. The dove is also known by the names of green dove and green-winged pigeon. The common emerald dove is the state bird of the Indian state of Tamil Nadu. The Pacific emerald dove and Stephan's emerald dove were both considered conspecific.
The common ground dove is a small bird that inhabits the southern United States, parts of Central America, the Caribbean and northern South America. It is considered to be the smallest dove that inhabits the United States. As its name suggests, the bird spends the majority of its time on the ground walking but still has the ability to fly.
The black-faced grassquit is a small bird. It is recognized as a tanager closely related to Darwin's finches. It breeds in the West Indies except Cuba, on Tobago but not Trinidad, and along the northern coasts of Colombia and Venezuela.
The scaled pigeon is a large New World tropical dove. It is a resident breeder from southern Mexico south to western Ecuador, southern Brazil, northern Argentina, and Trinidad.
The Cuban amazon also known as the Cuban parrot and the rose-throated parrot, is a medium-sized mainly green parrot found in woodlands and dry forests of Cuba, the Bahamas and Cayman Islands in the Caribbean. Although they have been observed in the wild in Puerto Rico, they are probably the result of escaped pets, and no reproduction has been recorded.
The jambu fruit dove is a smallish colourful fruit dove. It is a resident breeding species in southern Thailand, Malaysia, Brunei and the Indonesian islands of Kalimantan, Sumatra and Java.
The zenaida dove is a member of the bird family Columbidae, which includes doves and pigeons. It is the national bird of Anguilla, where it is locally referred to as "turtle dove".
The ruddy quail-dove is a species of bird in the dove and pigeon family Columbidae. It breeds throughout the West Indies, Central America, and tropical South America. It has appeared as a vagrant in Florida and southern Texas. It lays two buff-colored eggs on a flimsy platform built on a shrub. Some nests are built on the ground.
Patagioenas is a genus of New World pigeons whose distinctness from the genus Columba was long disputed but ultimately confirmed. It is basal to the Columba-Streptopelia radiation. Their ancestors diverged from that lineage probably over 8 million years ago. While the biogeographic pattern of this group suggests that the ancestors of the typical pigeons and turtle-doves settled the Old World from the Americas, Patagioenas may just as well be the offspring of Old World pigeons which only radiated into different genera later, given that the cuckoo-doves (Macropygia) of Southeast Asia also seem to be closely related.
The Caribbean dove is a species of bird in the family Columbidae. It is found in Belize, the Cayman Islands, Colombia, Honduras, Jamaica, and Mexico. It has been introduced to the Bahamas.
The blue-headed quail-dove, or blue-headed partridge-dove, is a species of bird in the pigeon and dove family Columbidae. It is monotypic within the subfamily Starnoenadinae and genus Starnoenas.
The Greater Antillean bullfinch is a species of bird in the family Thraupidae.
