La Palma de Nicoya, Guanacaste, western Costa Rica.
In past, sometimes considered conspecific with M. cinerascens, but differs in mouth-lining colour, vocalizations, rectrix pattern, wing formula, and morphometrics; no evidence of hybridization between the two. Form flavidior may be a separate species, differing from others in voice and habitat, as well as plumage#R; presumed sympatry of flavidior with nominate in S Mexico (Oaxaca), S Nicaragua and Costa Rica (Guanacaste) and intergradation with inquietus over larger zone in Oaxaca require reinvestigation. All three taxa have been thought to occur in both pure and hybrid forms in Oaxaca; complex pattern of zones of contact between races has not been assessed since 1961, and study urgently needed. Three subspecies recognized.
