Hummingbirds (Trochilidae)

Broad-billed Hummingbird (Cynanthus latirostris) - HBW 5, p. 581

French: Colibri circé German: Blaukehl-Breitschnabelkolibri Spanish: Colibrí Piquiancho
Other common names: Doubleday’s Hummingbird (doubledayi); Lawrence’s Hummingbird (lawrencei)

Taxonomy: Cynanthus latirostris Swainson, 1827, tableland of Mexico; error = Valley of Mexico near Mexico City.
Possibly forms a superspecies with C. sordidus; a reported hybrid of these two apparently refers to variation within adult male of that species. Hybrids with Agyrtria violiceps and Eugenes fulgens documented suggest possible close relationship between these genera and Cynanthus. Race doubledayi sometimes considered a separate species; proposed race toroi represents specimens from zone of intergradation between propinquus and doubledayi; proposed race nitidus is synonym of doubledayi. Race lawrencei has also been cons.. View all taxonomy...

Taxonomy: Cynanthus latirostris Swainson, 1827, tableland of Mexico; error = Valley of Mexico near Mexico City.
Possibly forms a superspecies with C. sordidus; a reported hybrid of these two apparently refers to variation within adult male of that species. Hybrids with Agyrtria violiceps and Eugenes fulgens documented suggest possible close relationship between these genera and Cynanthus. Race doubledayi sometimes considered a separate species; proposed race toroi represents specimens from zone of intergradation between propinquus and doubledayi; proposed race nitidus is synonym of doubledayi. Race lawrencei has also been considered a distinct species. Racial differences mainly in male head coloration, though this may vary clinally, so number of valid races uncertain. Five subspecies recognized.
