Birds as indicators of change in marine prey stocks

  • Chapter
Birds as Monitors of Environmental Change

Abstract

For millenia humans have followed birds at sea to locate fish and mammals. Seabirds are highly visible wide-ranging upper trophic level consumers that can indicate marine productivity and biotic interaction. Compared with fish, marine mammals, and other animals that live primarily or exclusively underwater, seabirds are easy to survey, census and study. This chapter reviews the types, utilities and limitations of avian indicators of the condition of fish stocks and recommends research needed to improve understanding of avian trophic relationships.
