Abstract
I summarized data from 889 intensive 2-hour morning surveys between 1992 and 1997 to determine the distribution of marbled murrelets (Brachyramphus marmoratus) in suitable habitat (mature and old-growth forest stands) on the Roseburg District of Bureau of Land Management in southwestern Oregon. Murrelets were detected on 17 surveys at 6 sites. Three sites were considered occupied, as defined by the Pacific Seabird Group (PSG), Marbled Murrelet Technical Committee guidelines (Ralph et al. 1993; 1994), all were less than 59 km from the coast. The farthest inland site with detections was 61 km from the coast. Two potential variables are discussed, which may influence the patterns of distribution and abundance in the study area: energetics and predation. Using the PSG protocols, surveys in southwestern Oregon should be conducted in all suitable habitat located 60 km inland from the coast rather than the guidelines for 80 km
