Abstract

The House-swift (Apus affinis affinis, J. E. Gray) is a very rapid flier and it hawks high in the air for its food which normally comprises small insects such as mosquitoes and other dipterans. During their flight they keep their mouth open and it is closed when the prey comes in contact with the bill. A study of the functional anatomy of the feeding apparatus in this bird was undertaken to find out the adaptations which pertain to the epidermal structures of the bill, shape of the tongue, skull architecture and the cranial musculature operating the bill. Emphasis is laid on the musculature of the bill and tongue in light of the functions performed.
