Large-billed Crow (Corvus macrorhynchos)

The large-billed crow is relatively large all-black corvid. It is 46–59 cm (18–23 in) in length and 450–1,000 g (16–35 oz) in weight. It has a large black bill with an arched culmen. The base of the culmen is hidden by a layer of overlapping black rictal bristles. The glossy black plumage has a purple sheen. The bases of the neck feathers are pale grey. The throat has elongated hackle feathers. The irises are dark brown and the legs are black. The sexes are similar in plumage but the female, on average, is smaller than the male and has a less arched culmen. Voice: The voice is similar to the house crow to which it is closest, but deeper and usually more resonant and described as the usual loud "caa-haa-caa". However, it makes a range of calls, some which could be described as "cau cau" and others that could be mistaken for a woodpecker drumming.
