Foraging Ecology and Post-Breeding Dispersal of the Xantus' Murrelet in the Southern California Bight
Entry ID: brdwerc003

[ Update this Record ]

Abstract: The Xantus' Murrelet is one of the rarest seabirds in the world with a
population of less than 10,000 breeding individuals. It is distributed in a
restricted area from the Channel Islands of southern California to Guadalupe
Island in northwestern Mexico. The species is vulnerable to a host of threats
including oil spills in shipping and drilling areas, discharge from the Los
Angeles area, non-native predators, and military activities.

Purpose: APPLICATION OF RESEARCH: This radio telemetry project was designed to
examine murrelet at-sea ecology and distribution, as well as, colony attendance
and post-breeding dispersal.
