American White Pelican - Pelcanus erythrorhynchosThe American White Pelican is one of the largest birds found in South Dakota.  They are migrants through most of the state, but do nest in some of the northeastern counties.   Unlike their cousins, the Brown Pelican, American White Pelicans do not plunge dive, but feed by dipping their large pouched bill into the water and scooping up fish.  Note the raised bump on the top of the beak (shown in bird to the right) is only present during the breeding season.

Habitat: Lakes, marshes, rivers.  Nests on isolated islands and sandbars, may feed many miles from nesting site. 

Diet: Mostly fish, also salamanders and crustaceans. 

Behavior: Feeds by dipping bill into the water and scooping up prey.  They will often forage together in groups, lining up and driving prey fish to shallower waters for easier capture.

Nesting: May through August. The nest of an American White Pelican is a depression on the ground, with a built-up rim of mud, rocks, and plants.  The female lays 2 eggs, and both parents help to incubate them.  When the eggs hatch, both parents help to feed the young.  The young fledge at about 10 weeks.

Song: Mostly silent.

Migration: Winters along Gulf Coast, California, and Mexico.  

Similar Species: Brown Pelican

Status: Due to habitat loss and disturbance at nesting colonies, populations declined substantially up through the middle part of the 20th century.  Numbers have increased in the past few decades.  The IUCN lists the American White Pelican as a species of "Least Concern".
