Anorrhinus Reichenbach, 1849


Avium systema naturale pl.XLIX

Anorrhinus is a genus of hornbills (family Bucerotidae) found in forests of south-east Asia (just barely extending into adjacent parts of India and China). They are social and typically seen in groups, but only the dominant pair are believed to breed, while other group members act as helpers.


This genus is sometimes limited to the Bushy-crested Hornbill, in which case the two remaining species, which sometimes are considered conspecific, are placed in the genus Ptilolaemus.

* Austen's Brown Hornbill, Anorrhinus austeni
* Tickell's Brown (or Rusty-cheeked) Hornbill, Anorrhinus tickelli
* Bushy-crested Hornbill, Anorrhinus galeritus
