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 casqueextending 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. 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
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. The female has a more
yellowish bill with black on the basal half and on the casque.
The call is a squealing
call somewhat like that of a black kite. The flight is heavy and involves flapping
interspersed with glides.
