Least Concern

Grey-headed Chachalaca (Ortalis cinereiceps)


Taxonomy

French: Ortalide à tête grise German: Graukopfguan Spanish: Chachalaca cabecigrís
Taxonomy:

Ortalida cinereiceps

“north-west coast of America”; error = probably Pearl Islands, Panama

.

Closely related to O. garrula, of which has been considered a race, but differs in voice and plumage, and, despite claims of sporadic hybridization in wild, the two are separated by stretch of dense forest probably unsuitable for any Ortalis. Several races (frantzii, mira, olivacea, chocoensis) proposed on basis of colour tone, but differences slight and essentially clinal. Monotypic.

Distribution:

E Honduras (Mosquitia), E & C Nicaragua, Costa Rica (except drier NW), Panama (including I del Rey, in Pearl Is, where perhaps introduced by native American Indians) and adjacent NW Colombia (Chocó).
