Double-crested Cormorants are common breeders through south coastal Alaska west to the eastern Aleutian Islands. In the Pribilofs however, they are merely casual visitors. Often these cormorants will linger around the island for weeks when they arrive. Any cormorant seen on one of the islands freshwater lakes should be scrutinized carefully, as Red-faced and Pelagic Cormorants do not come inland. On adult or second year birds look for the large size, orange lores and throat and dark flank to separate this species from the regular Pribilof cormorants. Younger Double-crested Cormorants will show whitish underparts, a feature not shared by Red-faced or Pelagic Cormorants.
