The California Brown Pelican, a subspecies of the Brown Pelican (Pelecanus occidentalis), is the smallest member of the pelican family. On the Pacific Coast, Brown Pelican adults have red skin on their throats in the breeding season. On the Atlantic and Gulf Coasts, Brown Pelicans are slightly smaller and their throat skin is greenish black. The only breeding colonies of California brown pelicans in the western United States are within Channel Islands National Park on West Anacapa and Santa Barbara islands. The California brown pelican is a permanent resident of the coastal marine environment on the Pacific Coast and the range extends from British Columbia, Canada, south to Nayarit, Mexico. Five subspecies of the brown pelican are recognised – californicus, carolinensis, occidentalis, murphyi, and urinator.
