Bananaquit

The bananaquit was formally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Certhia flaveola. Linnaeus based his description on the "black and yellow bird" described by John Ray and Hans Sloane, and the "Black and Yellow Creeper" described and illustrated by George Edwards in 1751. The bananaquit was reclassified as the only member of the genus Coereba by Louis Pierre Vieillot in 1809. The genus name is of uncertain origin but may be from a Tupi name Güirá for a small black and yellow bird. The specific epithet flaveolus is a diminutive of the Latin flavus meaning "golden" or "yellow". Before the development of techniques to sequence DNA, the relationship of the bananaquit to other species was uncertain. It was variously placed with the New World warblers in the family Parulidae, with the buntings and New World sparrows in the family Emberizidae, or in its own monotypic family Coerebidae. Based on the results of molecular phylogenetic studies, the bananaquit is now placed in the tanager family Thraupidae and belongs with Darwin's finches to the subfamily Coerebinae. It is still unclear if any of the island subspecies should be elevated to species, but phylogenetic studies have revealed three clades: the nominate group from Jamaica, Hispaniola, and the Cayman Islands, the bahamensis group from the Bahamas and Quintana Roo, and the bartholemica group from South and Central America, Mexico (except Quintana Roo), the Lesser Antilles and Puerto Rico.

The bananaquit is a small bird, although there is some degree of size variation across the various subspecies. Length can range from . Weight ranges from . Most subspecies of the bananaquit have dark grey (almost black) upperparts, black crowns and sides of the head, a prominent white eyestripe, grey throat, white vent, and yellow chest, belly, and rump. Coloration is heavily influenced by melanocortin 1 receptor variation. The sexes are alike, but juveniles are duller and often have partially yellow eyebrows and throat. In the subspecies bahamensis and caboti from the Bahamas and Cozumel, respectively, the throat and upper chest are white or very pale grey, while ferryi from La Tortuga Island has a white forehead. The subspecies laurae, lowii, and melanornis from small islands off the coast of northern Venezuela are overall blackish, while the subspecies aterrima and atrata from Grenada and Saint Vincent have two plumage morphs, one "normal" and another blackish. The pink gape is usually very prominent in the subspecies from islands in the Caribbean Sea. The tongue is paddle-shaped, with an extremely long paddle section. == Distribution and habitat==

, Costa Rica It is resident in tropical South America north to southern Mexico and the Caribbean. It is found throughout the West Indies, except for Cuba. == Behaviour and ecology ==

National Park in Dominica The bananaquit has a slender, curved bill, adapted to taking nectar from flowers, including mistletoes. Nectivory is probably an independent innovation in Coereba. Since then C. flaveolas tongue shape has shown convergent evolution with other birds feeding on the same flowers, and its source flowers have shown convergence to accommodate its tongue. It also feeds on fruits - including mistletoe fruits, other berries, and ripe bananas (hence the common name and bananivora for the Hispaniolan subspecies). It has been observed taking fruits' sweet juices by puncturing fruit with its beak and it will also eat small insects (such as ants and flies), their larvae, and other small arthropods (such as spiders) on occasion. While feeding, the bananaquit must always perch, as it cannot hover like a hummingbird. It may also build its nest in human-made objects, such as lampshades and garden trellises. The birds breed all year regardless of season and build new nests throughout the year. == References == == Literature cited ==
