ズグロコセイインコ Psittacula himalayana

A medium-sized parakeet with a bluish-gray head, green body, red bill, and yellow-tipped tail. Males and females are alike, except that males have a red patch on the shoulder. Often found in large flocks which feed on fruits, blossoms, and crops. The call is a harsh, grating screech with a metallic quality. Similar to Gray-headed Parakeet, but Slaty-headed Parakeet has a darker head, an indistinct black collar, and a different call.
