Summary
Description
Previous studies have raised concerns about the organochlorine pesticide concentrations in the eggs of tern species in Southern California including the California least tern Sterna antillarum browni, Boardman 1988 and Caspian tern Sterna caspia, Ohlendorf et al. 1985. The eggs analyzed in this study were eggs which failed to hatch at several San Diego Bay colonies. All black skimmer, Caspian tern, Forsters tern, elegant tern, gullbilled tern, and western snowy plover eggs were from the Salt Works located in south San Diego Bay. One of the California least tern eggs was also collected there. The contents of these eggs were tested for analytes and eggshell thickness was recorded.
