attribute NC_GLOBAL summary String Annual breeding population estimates for Brandt's Cormorant, Cassin's Auklet, Common Murre, Double-crested Cormorant, Pelagic Cormorant, Pigeon Guillemot, Tufted Puffin, and Western Gull at the Farallon Islands. Data presented are the number of breeding adults estimated for each season.

Breeding population estimates for most species are based on either direct counts of animals or nests. Cassin's auklet estimates are based on the percent change in burrow/crevice density within a series of index plots. This relative change is then applied to the last full census from 1989 to arrive at a current population estimate. See the SEFI Research Plans and Protocols document under Research Tools for more information on how these estimates were determined.

Note: Cassin's auklet population estimate is for Southeast Farallon Island only.
