Other common names: Mexican Grassquit

Taxonomy: Emberiza olivacea Linnaeus, 1766, Dominica = Hispaniola.
Genus may belong in tanager family (Thraupidae); appears to be part of a clade which also includes several Caribbean genera (Euneornis, Loxipasser, Melopyrrha, Loxigilla, Melanospiza), Bananaquit (Coereba flaveola), and “Darwin’s finches” (Certhidea, Platyspiza, Pinaroloxias, Camarhynchus, Geospiza). Molecular data suggest that genus as currently constituted is polyphyletic; further research required. Proposed race coryi (described from Cayman Brac, in Cayman Is) is synonymized with nominate.
