Yellow-faced Grassquit (Tiaris olivaceus) [XC704504]

Subspecies
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 is required.

Proposed subspecies coryi (described from Cayman Brac, in Cayman Is) is synonymized with nominate.

The following 5 subspecies are recognised:

  • pusillus Swainson, 1827   -  Atlantic slope of Mexico southern locally through Central America to Colombia (west of eastern Andes, excluding Santa Marta region) and north-western and eastern Ecuador, and western Venezuela (south-western Mérida and Táchira).
  • intermedius (Ridgway, 1885)   -  Cozumel I (off Quintana Roo), in eastern Mexico.
  • ravidus Wetmore, 1957   -  Coiba I (off southern Veraguas), in western Panama.
  • olivaceus (Linnaeus, 1766)   -  Cuba, I of Pines, Cayman Is, Jamaica and Hispaniola.
  • bryanti (Ridgway, 1898)   -  Puerto Rico and neighbouring islands.
