The blue gloss can be seen on the bird's feathers. The Raven tore pieces off the meat carcass and hid them in various places, to return to later.

Also called the Common or Northern Raven, its range covers most of the northern hemisphere. Like crows (and humans), these long-lived birds (up to some 20 years) congregate in gangs as juveniles before (unlike humans) mating for life; they may rejoin flocks if single in old age.
