We conducted a capture-recapture study on the population size and trends of the Ashy Storm-petrel (Oceanodroma homochroa) on Southeast Farallon Island (SEFI), California, based upon data collected in 1971, 1972, and 1992. From March through August, birds were lured to fixed-site sampling locations using taped vocalization playback. Using program JOLLY, we estimated population size and evaluated statistical models using goodness-of-fit and Likelihood Ratio tests. On the southwestern slope of…

Seabirds as part of migratory owl diet on Southeast Farallon Island, California

The introduction of non-native mammals is often a primary factor in the decline or extirpation of seabird populations on islands worldwide (Croxall et al. 2012). The Farallon Islands (hereafter,

Rhinoceros Auklet (Cerorhinca monocerata) Burrow Counts, Burrow Density, Occupancy Rates, and Associated Habitat Variables on Protection Island, Washington: 2008 Research Progress Report

Unlike many species of seabirds that use the Salish Sea (Puget Sound, Georgia Basin and Strait of Juan de Fuca) during migration or for over-wintering, rhinoceros auklets (Cerorhinca monocerata)

Ashy Storm-Petrel Oceanodroma homochroa mist-netting and capture rates in the California Channel Islands, 2004-2007

The Ashy Storm-Petrel Oceanodroma homochroa (ASSP) is endemic to the California Current System (CCS) and nests only on Californian islands, islets and rocks (including the Pacific coast of northern


In 1995-1998 and 2005-2007, reproductive performance of the ashy storm-petrel (Oceanodroma homochroa) was measured at four sea caves and one offshore rock at Santa Cruz Island, California. In


We report the first known nesting of the Ashy Storm-Petrel and Cassin's Auklet in Monterey County, California, on offshore rocks around Castle Rock and Hurricane Point. Four nests and 13 mist-netted

Storm-petrels of the Eastern Pacific Ocean: Species Assembly and Diversity along Marine Habitat Gradients

from about 50°N to 50°S and out along the equator, are 26 distinct taxa of storm-petrels (Hydrobatidae), a diversity far greater for this group than in any equivalent stretch of the world ocean. We

Range-wide conservation and science of the Ashy Storm-Petrel Oceanodroma homochroa

The Ashy Storm-Petrel Oceanodroma homochroa (hereafter, ASSP) is endemic to the California Current System (CCS) and breeds among the limited number of islands and coastal rocks available along the

A Model Approach for Estimating Colony Size, Trends, and Habitat Associations of Burrow-Nesting Seabirds

A prototype monitoring strategy for estimating the density and number of occupied burrows of burrow-nesting seabirds at single- or multi-island scales is presented and suggests that the Salish Sea population has increased, despite greater human effects on that ecosystem.

Recapture processes and biological inference in monitoring burrow-nesting seabirds

It was found that the recapture probability varied over time and among methodologies, and the differences found in survival seem to depend on the biological variability between sites (e.g. predation pressure), and not on the recaptures methods.



Late Spring Observations on Birds of South Farallon Island, California

The Farallon Islands, situated about 27 miles west of San Francisco, have long attracted the attention of ornithologists because of their enormous breeding colonies of sea birds and the rather

Upper trophic level predators indicate interannual negative and positive anomalies in the California Current food web

P perturbations in the marine food web of the Cal~fornia eastern boundary current system, as indicated by the availability of food to seabirds, are much more complex than is generally appreciated, and are not conf~ned only to negative excursions from normalcy.
