Races form two groups, N “white-bellied group” (first four races listed) and S “yellow-bellied group” (last four races). Latter group sometimes treated as separate species, differing in its yellow vs white belly (3); pale chestnut vs rufous crown (1); lack of repetition of identical notes in song, but with a cline towards this where it approaches white-bellied group and with such repetitions fully present in race salvini (ns)#R; narrow white collar-line behind ear-coverts, a character of white-bellied group, also present in yellow-bellied salvini (ns). Interbreeding between the two groups apparently extensive in Guatemala, and possibly also in S Mexico (SE Chiapas), El Salvador and Honduras. Proposed race flavigaster (N Oaxaca) synonymized with nominate race. Eight subspecies recognized.
