Image 15128, Brown pelican.  This large seabird has a wingspan over 7 feet wide. The California race of the brown pelican holds endangered species status, due largely to predation in the early 1900s and to decades of poor reproduction caused by DDT poisoning.  In winter months, breeding adults assume a dramatic plumage with brown neck, yellow and white head and bright red gular throat pouch.
