Hawks and Eagles (Accipitridae)

Hook-billed Kite (Chondrohierax uncinatus) - HBW 2, p. 109

French: Milan bec en croc German: Langschnabelweih Spanish: Milano Picogarfio

Taxonomy: Falco uncinatus Temminck, 1822, Bahia, Brazil.
Large billed forms have been suggested to form a separate species (C. megarhynchus), but this view now discredited; race wilsonii of Cuba also recognized by some as full species. Mexican birds traditionally awarded separate race, aquilonis, but considerable individual variation (both in Mexico and elsewhere) indicates that subspecific status is not merited. Three subspecies recognized.

Subspecies and Distribution:

  • uncinatus (Temminck, 1822) - W Mexico (Sinaloa) and extreme S USA (S Texas) S through Central America, Trinidad, the Guianas and Brazil to E Peru and E Bolivia, Paraguay and N Argentina.
  • mirus Friedmann, 1934 - Grenada (Lesser Antilles).
  • wilsonii (Cassin, 1847) - E Cuba.
