ID tip
The thick-billed raven averages 64 cm (25 in) in length, with a range of 60 to 70 cm (24 to 28 in) and weighs approximately 1.15 kg (2.5 lb) in females and 1.5 kg (3.3 lb) in males on average. Its size is about the same as the largest subspecies of common raven (i.e. those from the Himalayas and Greenland/Canadian Northwest Atlantic) but some common raven subspecies are rather smaller and, going on average weights, the thick-billed raven is likely the heaviest extant passerine. Voice: Its calls include a harsh nasal croak, a low wheezy croak, a "raven-raven", and sometimes a "dink, dink, dink" sound. Like many corvids, the thick-billed raven is capable of vocal mimicry; however, this behaviour is rare in the wild, and is normally recorded only in captivity.
