Abstract

Background: The sternum is one of the most important and characteristic skeletal elements in birds, highly adapted for flight and showing a diverse range of morphogenesis. The Asian koel (Eudynamys scolopaceus) is a member of the Cuckoo order of birds, found in the Indian sub-continent, China and Southeast Asia. The present study was carried out as anatomical data on the sternum of this species is scanty.  
Methods: Carcass of Asian koel brought to the Department of Wildlife Science, Madras Veterinary College, Chennai after the post-mortem examination was biologically macerated, cleaned, dried and morphological and morphometric studies were performed. 
Result: Gross morphological and morphometric data of the sternum of Asian koel was compared with other avian species. The sternum of Asian koel was large, broad, quadrilateral shaped and highly pneumatized bone with well developed sternal crest, craniolateral and caudolateral processes. These features provide protection to the viscera and facilitates superior flight.
