Article abstract: The University of California at Irvine (UCI) manages the UCI Ecological Preserve, a 60 acre area of natural habitat located on the main UCI campus. The Preserve has been subject to ongoing avian surveys and ecological restoration efforts for over a decade. In 2002, UCI contracted Harmsworth Associates to conduct surveys for the California gnatcatcher (Polioptila californica californica) and cactus wren (Campylorhynchus brunneicapillus) to determine the number and location of breeding pairs of each species at the Preserve. This report summarizes the results of surveys for gnatcatcher and cactus wren for the 2005 season.
