The Brown Pelican (Pelecanus occidentalis), an endangered species, feeds on schooling fish near the ocean's surface by plunging beak-first from the air. The chemical DDT almost caused the demise of the brown pelican back in the 1960's. Pelicans exposed to DDT laid eggs with thin or non-existent shells, which broke during nesting, thus reducing the number of surviving offspring. Since DDT was banned in 1972, brown pelicans have made a remarkable recovery. There are permanent brown pelican nesting colonies on both Anacapa and Santa Barbara Islands.
