The present study aimed to throw light upon the pectoral limb bones of common hawk cukoo (Hierococcyx varius) and yellow billed babbler (Argya affinis). Typical pectoral girdle was present in both the birds. The clavicles of common hawk cukoo joined at more open angle compared to yellow billed babbler. The direction of clavicle was backward in common hawk cukoo and downward and posteriorly in yellow billed babbler. The humerus consisted of prominent tuber for muscular attachment above the pneumatic foramen in common hawk cukoo. Comparatively large interosseous space observed between the radius and ulna bones of yellow billed babbler. The lateral surface of ulna in common hawk cukoo showed the six prominences for the roots of the flight feathers. The length of ulna was larger than humerus in common hawk cukoo and that of humerus was longer than radius and ulna in yellow billed babbler. This shows poor flying capability in yellow billed babbler than common hawk cukoo.
