Costa's Hummingbird (Calypte costae)


French: Colibri de Costa German: Veilchenkopfelfe Spanish: Colibrí de Costa

Ornismya Costæ


, 1839,

Magdalena Bay, Baja California, Mexico


Closely related to C. anna; sometimes regarded as being closest to Archilochus, but such a relationship seems unlikely. Has hybridized with several other W North American trochilids, including C. anna, Lampornis clemenciae, Archilochus alexandri, Selasphorus platycercus and S. calliope. Monotypic.


SW USA (from C California, S Nevada and extreme SW Utah) S to NW Mexico (to S Baja California and C Sonora). Winters S to WC Mexico (at least to Nayarit).
