Hummingbirds (Trochilidae)
Azure-crowned Hummingbird (Agyrtria cyanocephala) - HBW 5, p. 598
French: Ariane à couronne azur
German: Blaukopfamazilie
Spanish: Amazilia Coroniazul
Other common names: Red-billed Azurecrown; Mosquitia Hummingbird (chlorostephana)
Taxonomy: Ornismya cyanocephalus Lesson, 1829, Brazil; error = Veracruz, Mexico.
Genus usually merged into Amazilia. Race chlorostephana has been suggested as possibly approaching species status, but nominate (in E of range) shows clinal variation in crown colour towards chlorostephana. Birds from Belize S to N Nicaragua formerly separated as race guatemalensis, but specimens from C & E Guatemala, including type locality of guatemalensis, Dueñas, show strong intergradation with nominate birds from Chiapas (S Mexico).

Genus usually merged into Amazilia. Race chlorostephana has been suggested as possibly approaching species status, but nominate (in E of range) shows clinal variation in crown colour towards chlorostephana. Birds from Belize S to N Nicaragua formerly separated as race guatemalensis, but specimens from C & E Guatemala, including type locality of guatemalensis, Dueñas, show strong intergradation with nominate birds from Chiapas (S Mexico). Proposed species “A. microrhyncha” (Honduras, Nicaragua), known from two specimens and separated in part on basis of unusually short bill, does not merit even subspecific recognition because characters appear to be based on individual variation or juvenile, probably of nominate. Two subspecies recognized.
Subspecies and Distribution:
- cyanocephala (Lesson, 1829) - E & S Mexico to E Honduras and NC Nicaragua.
- chlorostephana (Howell, 1965) - Mosquito Coast of E Honduras and NE Nicaragua.
