Nesting
Breeds in mixed colonies with other seabirds. In display, male perches with head over back, bill pointed up, moving head up and down, while quickly raising and lowering tips of folded wings so that white patches on flanks are rapidly covered and exposed, appearing to flash on and off. Nest: site is on ledge (wide or narrow) of cliff or steep slope above water. Nest is mound of grass, seaweed, moss, debris, with deep hollow in center, sometimes lined with feathers. Nest may be re-used in subsequent years.
Climate Vulnerability
Conservation Status
Population in Aleutians thought to have been increasing for several decades. Since late 1950s has expanded range east along south coast of Alaska, becoming very common east to Prince William Sound. Despite increase, remains vulnerable to oil spills and other pollution.
