The Cuban Grassquit (Tiaris canorus) is a small bird formerly placed with the Emberizidae. It is now recognized as a Tanager closely related to Darwin’s Finches. It is found in Bahamas, Cuba, and Turks and Caicos Islands.
Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, subtropical or tropical dry shrubland, and heavily degraded former forest. [Wikipedia]
The Cuban Grassquit is small with olive upper parts, and conspicuous yellow crescent divides face and breast. Males are characterized by their black mask and breast patch that strongly contrast with the orange and yellow collar that reaches to just behind the eye and their gray crown and belly. Females are similar in their color patterns but have a more washed out version of the male’s colors with fewer mark on their faces. [Psu.edu]
