The Barbados bullfinch (Loxigilla barbadensis) is a seedeater bird that is found only on the Caribbean island-nation of Barbados, where it is the only endemic bird species.

Taxonomy

The Barbados bullfinch was previously considered a subspecies of the Lesser Antillean bullfinch (Loxigilla noctis), which is found on neighboring islands.[2] Despite the misleading nature of its name, the Barbados bullfinch is not a bullfinch at all but a seedeater. The bird is known locally as a Sparrow.

Description

The Barbados bullfinch is a small bird, 14–15 cm (5.5–6 in). The upperparts are a dark olive-grey, the wings are mostly brown, underparts are greyish, while the under tail-coverts are tawny. The species is not sexually dimorphic, with females and males having similar plumage. The birds' calls include simple twittering, an occasional harsh petulant note, and a sharp trill .

Distribution and habitat

The Barbados bullfinch is found only on the island of Barbados. The birds' habitat includes shrubbery and forest undergrowth; the species has adapted well to humans, often being found in close proximity to areas of human habitation, such as gardens.

Reproduction

Barbados bullfinches construct a globular nest, with a side entrance, in a tree or shrub. The species lays two to three spotted eggs.

Behavior

Barbados bullfinches are extremely innovative[3][4][5] and tame birds. Barbados bullfinches living in urban environments were found to have better problem-solving skills and a better immunocompetence than the ones living in rural areas of Barbados[6]. As for their temperament, urban Barbados bullfinches were found to be bolder but more neophobic than their rural counterparts[6].
