Black-faced Grassquit
Tiaris bicolor

 

Another small bird common throughout the island is the Black-faced Grassquit. Keep an eye open around the hotels, because you may not hear them—this species is quiet and unobtrusive and could be overlooked if you aren’t on the look-out for it. Males are a dull greenish color on the back with black undersides. Females are browner overall with lighter underparts. Both males and females sing.
