Vertebrate prey handling in the Indian Grey Hornbill Ocyceros birostris (Aves: Bucerotiformes: Bucerotidae)

Abstract

Most hornbills are omnivorous, but there are few specific records of how vertebrate prey are handled by hornbills, particularly in Asia. I describe an observation of a pair of Indian Grey Hornbills Ocyceros birostris handling a large vertebrate prey item (Garden Lizard Calotes versicolor) which included both manipulation (crushing) in the bill and repeated wiping on the branch of a tree, the latter technique undescribed for this or other species of hornbill. Likely reasons for this behaviour are discussed.
