Due to their existence at the boundary layers of the atmosphere and the ocean, seabirds are the most conspicuous of all marine organisms which rely on surface and near-surface ocean habitats. Seabirds also are less exploited than other upper-level predators such as fish and mammals. Owning these and other characteristics, seabirds have been put forth as reliable ecological indicators of coupled physical-ecological change. In this project, we are investigating changes in the abundance, distribution, and spatial organization of seabirds in the California Current. In this study Farallon Institute biologists make counts of seabirds from fisheries research vessels.
