Tyrant-flycatchers (Tyrannidae)

Nutting's Flycatcher (Myiarchus nuttingi) - HBW 9, p. 437

French: Tyran de Nutting German: Pazifischer Schopftyrann Spanish: Copetón de Nutting
Other common names: Pale-throated Flycatcher

Taxonomy: Myiarchus nuttingi Ridgway, 1882, La Palma de Nicoya, Guanacaste, western Costa Rica.
In the 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. Nominate race intergrades with flavidior in S Mexico (Oaxaca), S Nicaragua and Costa Rica (Guanacaste), and with inquietus over larger zone in Oaxaca; all three races 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.
