Hornbills (Bucerotidae)

Sri Lankan Grey Hornbill (Ocyceros gingalensis) - HBW 6, p. 497

French: Calao de Ceylan German: Ceylontoko Spanish: Cálao Gris Cingalés

Taxonomy: Buceros Gingalensis Shaw, 1811, Colombo, Sri Lanka.
Genus sometimes combined with African Tockus, but separated by differences in feeding behaviour at nest. Sometimes considered to form a superspecies with O. griseus, or the two often treated as conspecific, but differences in bare-part colours and in some aspects of behaviour and morphology suggest better treated as separate species. Monotypic.

Distribution: Sri Lanka.
