Common Ravens (Corvus corax) Prey on Rhinoceros Auklet (Cerorhinca monocerata) Eggs, Chicks, and Possibly AdultsFaculty Publications
AbstractWe observed Common Ravens ( Corvus corax) on Protection Island, Washington that used their bills to dig into the nesting burrows of Rhinoceros Auklets ( Cerorhinca monocerata) and prey on auklet eggs. In addition, we observed a raven fly away from a burrow with an auklet chick, a raven attack and unsuccessfully attempt to capture an adult auklet, and a raven fly with and feed on a freshly killed adult auklet. Although Common Ravens have been reported to prey on Rhinoceros Auklets' eggs, to our knowledge this is the first report of a raven preying on a chick and the first report of an attempt by a raven to capture an adult auklet.
