The Indian grey hornbill (Ocyceros birostris) is a common hornbill found on the Indian subcontinent. It is mostly arboreal and is commonly sighted in pairs. It has grey feathers all over the body with a light grey or dull white belly. The horn is black or dark grey with a casque extending to the point of curvature of the horn. It is one of the few hornbill species found in urban areas in many cities where they are able to make use of large trees in avenues.


The Indian grey hornbill is a medium-sized hornbill, measuring around 61 cm (24 in) in length.[2] The upper parts are greyish brown and there is a slight trace of a pale supercilium. The ear coverts are darker. The flight feathers of the wing are dark brown with a whitish tip. The tail has a white tip and a dark subterminal band. They have a red iris and the eyelids have eyelashes. The casque is short and pointed.[3]

The male has a larger casque on a dark bill, and the culmen and lower mandible are yellowish. The bare skin around the eye is dark in the male, but sometimes pale reddish in females.[4] The female has a more yellowish bill with black on the basal half and on the casque.[2][5][6] The juveniles lack the casque, and the bare skin around the eye is dull orange.[7]
