This glossy Tachycineta swallow has a green head and back, blue upper wings, a black tail and wingtips, and a white belly and chin.

[6] T. cyaneoviridis is endemic to the Bahamian pineyards, though they are somewhat capable of adapting to urban habitat.

Although they do not breed in marshland and fields, they need such habitat to forage; like all swallows, they feed on flying insects.

Bahama swallows nest in old West Indian woodpecker (Melanerpes superciliaris) holes in Caribbean pine (Pinus caribaea var.

bahamensis), using pine needles, twigs of trees from the genus Casuarina (introduced species in the Bahamas), and grass to make the nest, and they line it with feathers from other passerines.
