The present study was undertaken to provide a reference for the comparative gross anatomy of the sternum of the Black swan and the domestic fowl. The sternums of Black swan and fowl were procured from the postmortem room of the Department of Veterinary Pathology, College of Veterinary Science, Rajendranagar, Hyderabad and was macerated by wet method of maceration. The sternum showed two surfaces, two extremities and two borders. The anterior border of the sternum of swan was thick and convex while it was thin and triangular in the domestic fowl. The lateral border was concave and was seen with seven articular cylinders for the sternal ribs in swan while in fowl there were four articular facets. Craniolateral process was a short, flat and irregularly quadrilateral in Swan while it was large in the domestic fowl. The posterior extremity or metasternum also showed an irregularly quadrilateral plate with a notch in its middle while such notch was not seen in the domestic fowl. The two caudolateral processes were found in the fowl and single caudolateral process was noticed in the swan. The width to height ratio in swan was 1.57 mm in swan and 0.6mm in fowl.
