Marine bird attraction to thermal fronts in the California Current System
Hoefer, C.J. (2000) The Condor, 102(2):423-427
Abstract
I relate marine bird density to the 55 strongest thermal fronts encountered during a survey of much of the eastern portion of the California Current and the adjacent coastal upwelling region. Elevated densities were recorded for all marine bird taxa except the Leach's Storm-Petrel (Oceanodroma leucorhoa). The variance explained by the regression models ranged from 3% for the Leach's Storm-Petrel to 85% for all marine birds. The response observed is notably stronger than previous analyses with similar data.

Key words: California Current System, Leach's Storm-Petrel, Oceanodroma leucorhoa, pelagic ecology, seabird distribution, thermal fronts.
