Seabirds depend on nearshore and coastal habitats for foraging, roosting and breeding. As top predators, seabirds serve not only as vital components of marine ecosystems but may also be important indicators of ocean conditions. This project will focus on five species of seabirds that breed and nest within the North Coast region: Common Murre, Brandt's Cormorant, Double-crested Cormorant, Pelagic Cormorant, and Western Gull. Abundance, reproduction, and foraging habits will be documented over two years to establish a baseline of conditions for seabirds in the region. In addition, a region-wide census of seabird breeding populations will be taken through aerial surveys, and trends in seabird breeding populations will be assessed using existing photographs taken from 1996-2013. Researchers will also assess how seabirds use habitat in the region as well as rates of human disturbance at major breeding colonies. This project is a collaboration among academic scientists, non-profits, consultants, and federal agencies.
