Family Hummingbirds (Trochilidae)

Least Concern

Turquoise-crowned Hummingbird (Cynanthus doubledayi)


French: Colibri de Doubleday German: Blaugesicht-Breitschnabelkolibri Spanish: Colibrí piquiancho de Guerrero
Other common names: Doubleday's Hummingbird

Trochilus Doubledayi


, 1847,

presumably from the Rio Negro; error = Guerrero


Usually considered conspecific with C. lawrencei and C. latirostris; differs from latter in glittering turquoise-blue vs dull green crown (3); much more extensively royal-blue underparts (3); blue-black (not pale grey-white) undertail-coverts (2); fide recent authors#R#R more deeply cleft tail (seemingly so on museum specimens, but not measured; ns); shorter bill (effect size −3.94 vs latirostris; score 2); genetic evidence supports this split#R. Proposed race toroi represents specimens from zone of intergradation between C. latirostris propinquus and present species (for which a score of 2 might be given); proposed race nitidus is synonym of doubledayi. Monotypic.


Guerrero, Oaxaca and Chiapas, in S Mexico.
