The Jamaican blackbird (Nesopsar nigerrimus) is a species of bird in the New World blackbird and oriole family Icteridae. It is the only species (monotypic) in the genus Nesopsar. [2] The species has sometimes been included in the genus Agelaius , but molecular systematics have shown it not be closely related to any living New World blackbird or grackle. [3] The species is endemic to Jamaica, where it is restricted to Cockpit Country, some central areas and the Blue and John Crow Mountains.

Description

The Jamaican blackbird is a small icterid with all black plumage. [4] It has a short tail that is often flayed.

Habitat

It is strictly arboreal and has a wheezing call. Pairs occupy large territories in a variety of wet montane forest types, including elfin and mist forests, that have substantial epiphytes and mosses on the trees. The Jamaican blackbird's habitats are confined to areas of above 575m and are rarely seen in lowland areas.

Ecology

In the absence of specialised tree probers such as the woodcreepers, ovenbirds and woodpeckers (Jamaica does have a species of woodpecker, the Jamaican woodpecker, but it is a generalist that typically feeds away from tree trunks), which occur in similar forests on the mainland, the Jamaican blackbird has convergently evolved to fill this ecological niche. [5] The majority of the food taken by this species is found on the trunks of trees and their inner branches, feeding on animal prey, mostly insects, which it finds in bark or in bromeliads. It has shorter legs and longer claws that typical icterids, uses its tail for support when climbing tree trunks, both of which are adaptations to its niche, and has a longer bill and stronger jaw muscles than other New World blackbirds used for probing, spreading and hammering. It utilises a different niche from the other (semi) endemic icterid, the Jamaican oriole, which forages mainly in the outer branches of the trees.

Conservation

The principal threat to the Jamaican blackbird is habitat loss. [4] There are numerous threats to Jamaican forests, including bauxite mining, charcoal production, forestry, farming and development. This species is particularly vulnerable because it is dependent on large trees which support many epiphytes. Because of these threats it is listed as Endangered by the IUCN. It is protected in the Blue and John Crow Mountains National Park, and efforts are underway to stop bauxite mining in Cockpit Country.

Icterids or New World blackbirds make up a family, the Icteridae, of small to medium-sized, often colorful, New World passerine birds. The family contains 108 species and is divided into 30 genera. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. The name, meaning "jaundiced ones" comes from the Ancient Greek ikteros via the Latin ictericus. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas, and caciques.

<span class="mw-page-title-main">Baltimore oriole</span> Species of bird

The Baltimore oriole is a small icterid blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the coat-of-arms of 17-th century Lord Baltimore. Observations of interbreeding between the Baltimore oriole and the western Bullock's oriole Icterus bullockii, led to both being classified as a single species, called the northern oriole, from 1973 to 1995. Research by James Rising, a professor of zoology at the University of Toronto, and others showed that the two birds actually did not interbreed significantly.

The common grackle is a species of large icterid bird found in large numbers through much of North America. First described in 1758 by Carl Linnaeus, the common grackle has three subspecies. Adult common grackles have a long and dark bill, pale yellow eyes, and a long tail. Adults often have an iridescent appearance on their head, especially males. Common grackles can be found widely across North America east of the Rocky Mountains.

The Carib grackle is a New World tropical blackbird, a resident breeder in the Lesser Antilles and northern South America east of the Andes, from Colombia east to Venezuela and northeastern Brazil. There are eight subspecies, of which the most widespread is the nominate subspecies of Trinidad and the South American mainland. This subspecies was introduced to Tobago in 1905 and is now common there.

<span class="mw-page-title-main">Great-tailed grackle</span> Species of bird in North America

The great-tailed grackle or Mexican grackle is a medium-sized, highly social passerine bird native to North and South America. A member of the family Icteridae, it is one of 10 extant species of grackle and is closely related to the boat-tailed grackle and the extinct slender-billed grackle. In the southern and southwestern United States, the grackle is sometimes referred to simply as a "blackbird" or (erroneously) a "crow" due to its glossy black plumage; however, grackles form their own unique genus that is separate from other "blackbirds", such as the red-winged and Brewer's blackbirds, despite being in the same family (Icteridae). Superficially, Brewer's blackbird is one of the most visually similar species to grackles.

<span class="mw-page-title-main">Gleaning (birds)</span> Feeding behavior of plucking invertebrates from solid surfaces

Gleaning is a feeding strategy by birds in which they catch invertebrate prey, mainly arthropods, by plucking them from foliage or the ground, from crevices such as rock faces and under the eaves of houses, or even, as in the case of ticks and lice, from living animals. This behavior is contrasted with hawking insects from the air or chasing after moving insects such as ants. Gleaning, in birds, does not refer to foraging for seeds or fruit.
