White Pelicans can be some of the largest North American birds with a 9 foot wingspan and weighing between 9.2 to 30 pounds. They are identified by having large heads and yellow huge bills. For feeding the pelicans dip their bills to swallow fish. Historically White Pelicans were threatened with extinction due to DDT pesticides during the 1950s and 1960s but returned back to health due to stricter environmental protection laws. White Pelicans generally live in the lakes, marshes, and salt ponds most of the time. The birds are similar to Brown Pelicans except they are larger and don’t dive from the air for fish.
