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.
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.
Barbados bullfinches are extremely innovative 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. As for their temperament, urban Barbados bullfinches were found to be bolder but more neophobic than their rural counterparts.
Barbados bullfinches construct a globular nest, with a side entrance, in a tree or shrub. The species lays two to three spotted eggs.
