PIED-BILLED GREBE PREDATION ON A COMMON YELLOWTHROAT

Abstract

The Pied-billed Grebe (Podilymbus podiceps) is an opportunistic forager preying on a wide variety of aquatic organisms, including annelids, crustaceans, insects, mollusks, fishes, amphibians, and a snake (e.g., Wetmore 1924, Muller and Storer 1999, Storer 2000, Fjeldså 2004). In addition to live prey, it ingests copious quantities of its own feathers (Wetmore 1924). In this note we report the first observation of a Pied-billed Grebe preying upon a bird.
