Introduction The Double-crested Cormorant Phalacrocorax auritus (DCCO) is the most common cormorant seen on The Evergreen State College (TESC) campus coastline. The Brandt’s and Pelagic Cormorants are a rare sighting on the beaches of TESC. Of the three species, only the DCCO is commonly encountered in both salt and fresh inland waters, the other two are encountered on more open waters of the sound and the ocean. The Double-crested Cormorant is a diving bird feeding on schooling fish at mid depths. The DCCO may commonly be seen holding its wings out, this is to dry them off after diving. Populations are abundant and are perceived as a pest to some. The Double-crested Cormorant is about 33″ inches long, with a wing span of 52″ inches, and weighs 3.7 pounds. Juveniles are brownish, and the adults are almost black. They have an orange-ish yellow throat (Sibley, 2003).
