Winter Food Habits of Ravens on the Arctic Slope of Alaska
Analysis of 684 pellets from a winter roost of ravens (Corvus corax) at Umiat, Alaska, indicated that during the winters of 1966 and 1967 ravens obtained half of their energy income through predation and half through scavenging. Microtine rodents provided the bulk of the predatory half of the raven&...
