Abstract

We observed a common raven (Corvus corax) flying to an electrical transmission line tower with a Wilson's warbler (Cardellina pusilla) in its beak. Upon inspection of the ground under the tower, additional warbler carcasses were discovered. Questions arise with regard to predation versus scavenging, and it is often difficult to determine. However, knowing what species are considered prey by predators is a first step. Our observations were opportunistic and our report documents the collection of Townsend's (Setophaga townsendi) and Wilson's warblers by a common raven in the Mojave Desert.
