Gross Anatomical Studies on the Sternum of House Crow (Corvus splendens)

Abstract

Domestic crow is the most commonly observed passerine bird throughout India. For the present research six dead crows were utilized and the sternal bone was processed by the maceration process. The sternum of the crow was quadrilateral in shape and presented pneumatic foramina in the anterior half of the median groove. The craniolateral process was short and the caudolateral process, enclosing a lateral notch, was well developed. Through and through pneumatic foramen was replaced by a notch in fifty percent cases. The rostrum was typically Y shaped and the keel was strongly built. From the present study we conclude that the sternum of crow showed typical features of passerine birds. However, the sternum unlike the birds like bulbul, sparrow and myna presented well developed pneumatic foramina.
