Bald Eagles (Haliaeetus leucocephalus) were common on Catalina Island until the 1970s when the cumulative effects of the dumping of DDT off the Southern California Coast near San Pedro made it impossible for eagles to successfully hatch young. The eagles now on the Island are the product of a recovery effort undertaken by the Institute for Wildlife Studies on the protected lands of the Conservancy. Currently there are about two dozen Bald eagles on the Island including five nesting pairs.
The Orange-crowned Warbler (Vermivora celata) breeds widely over western and northern North America, and east across Canada. There are four recognized subspecies of this warbler. One of them, the sordida subspecies (Vermivora celata ssp. sordida), is endemic to the Channel Islands and reaches its highest density on Santa Catalina Island.
