Wikipedia Abstract

The black-faced grassquit (Tiaris bicolor) is a small bird formerly placed with the Emberizidae. It is now recognized as a tanager closely related to Darwins finches. It breeds in the West Indies except Cuba, on Tobago but not Trinidad, and along the northern coasts of Colombia and Venezuela. Males on the South American mainland have more extensively black underparts, shading to a grey belly. The black-faced grassquit feeds mainly on seeds, especially of grasses and weeds. It is often found in small groups, but is solitary at evening roosts.
