The largest corvids are the common raven (Corvus corax) and the thick-billed raven (Corvus crassirostris), both of which regularly exceed 1,400 grams (3.1 pounds) and 65 cm (26 in). Species can be identified based on size, shape, and geography; however, some, especially the Australian crows , are best identified by their raucous calls.
