Crows and ravens can be tricky to tell apart by sight, but their voices are much more distinctive. Watch this video for some expert tips on the sounds these two common birds make and what those sounds mean.
American Crows and Common Ravens have a repertoire of sounds beyond their signature “caw” and “kraa” calls. The crow often makes a rattle sound along with its territorial caw and also communicates through other click and bell-like notes. Ravens broadcast their presence through deep, throaty kraa calls. Narrator Kevin J. McGowan, an ornithologist at the Cornell Lab of Ornithology, uses harmless wing tags to study crows around the Cornell Lab. In this video, he compares the calls of American Crows with those made by Common Ravens.
