Do Rhinoceros Auklet, Cerorhinca monocerata, Fledglings Fly to the Sea from Their Natal Burrows?
Keywords:Rhinoceros Auklet, Cerorhinca monocerata, fledgling departure, Washington
AbstractThe mode of departure of Rhinoceros Auklet fledglings from their nest burrows has remained uncertain. Both walk-down and fly-down hypotheses have been proposed. Here we use the unique geography of Protection Island, Washington, to evaluate the fly-down hypothesis. Some fledglings raised on Protection Island do appear to walk to the water, but our results suggest that many of the island’s fledgling Rhinoceros Auklets fly to the sea.
