Cannibalism is uncommon in birds, and instances of adults killing and eating other adults are especially rare. Cases of intraspecific predation among passerines constitute a very small percentage of published reports, and many of the cases are based on circumstantial evidence. In July 2001, I witnessed a group of Northwestern Crows (Corvus caurinus) kill and consume a conspecific adult in Olympic National Park, Washington. I am aware of no other published reports of adult-adult cannibalism for this species or the Corvidae family.
