| Notes | A research project was carried out over two study periods (March-September 1986, March-August 1987) to determine the nest locations and nesting habitat of marbled murrelets (Brachyramehus marmoratus) in coastal Oregon . . . A suspected nesting area was found through the identification of calling murrelets at Remmy Creek, a forested basin in Douglas County located 44 km from the ocean. This 260 ha basin contains stands of old-growth conifers, principally Douglas-fir (Pseudotsuga menziesii), and is estimated to support three to five pairs of nesting marbled murrelets. Abundance surveys indicate that at-sea murrelet abundance in the study area is patchy, in that it declines with increasing distance from the mouths of rivers and bays, and varies from day to day in the same area. Based on murrelet density estimates in the study area, the breeding population of marbled murrelets in coastal Oregon is tentatively estimated to be approximately 2,500 pairs of birds. (p.1) |
