Ravens are omnivorous, consuming a wide variety of both
plant and animal matter. They are notorious scavengers and
are common visitors to garbage dumps, although at times
they are also predatory on small animals. Ravens will hide
or cache food supplies, and will raid other ravens’
caches, creating social dynamics involving disguising
caches and creating fake caches.
They also have the habit,
like most hawks and owls, of regurgitating undigestible
food in the form of a pellet. An analysis of hundreds of
raven pellets from Umiat, Alaska, indicated that 50
percent of the raven's winter diet consisted of live prey
(mostly small mammals) captured by ravens. Diets consist
of grains, berries, fruit, small invertebrates,
amphibians, reptiles, small mammals and birds.
