The American White Pelican (Pelecanus erythrorhynchos) is a huge bird!  With an 8 to 9 1/2 foot wingspan and weighing in at up to 30 pounds, it rivals the California Condor for size and weight.  They occur mainly in western and southern portions of North America, breeding inland in colonies on remote islands and wintering along warm southern coasts1.

Large flocks of these amazing birds are sometimes seen gracefully flying overhead in formation or soaring high on thermals.

In breeding plumage, adult American White Pelicans have a distinct “centerboard” or “horn” on the ridge of their bill.  I was lucky enough to catch this photo of an adult in flight at the Sacramento National Wildlife Refuge back in February showing the horn and their distinctive black and white plumage.

Two weekends ago, I took a little jaunt to Eagle Lake hoping to see the complete courtship display of the Western and Clark’s Grebes but alas, I was too late.  They are already nesting.  I did see several American White Pelicans though, including this immature bird (click on photos for full sized images).

The immature bird has a dusky wash on the head, neck and wings, fading to white by late summer or fall.

Unlike the Brown Pelican, the American White Pelican scoops up fish while swimming.

They begin feeding by dipping that huge bill into the water and scooping prey into their pouch, water flowing out of the pouch as they raise it back up to horizontal.

Then they raise their heads up to swallow their catch.

This youngster obviously has something pretty big in there

As the swallowing commences the pouch deflates again …

until the last of it goes down the gullet.

Apparently, nocturnal feeding is common during breeding season (but not during the winter) requiring the birds to feel the prey as it contacts the beak.   During the day prey is probably located by sight.

One interesting fact about the American White Pelican is that they sometimes forage in cooperative flocks, driving fish toward the shore where they are more easily caught.  I found this great video showing the cooperative foraging activity plus it shows the pelican in flight, a beautiful thing to see!

Larry Jordan was introduced to birding after moving to northern California where he was overwhelmed by the local wildlife, forcing him to buy his first field guide just to be able to identify all the species visiting his yard. Building birdhouses and putting up feeders brought the avian fauna even closer and he was hooked. Larry wanted to share his passion for birds and conservation and hatched The Birder's Report in September of 2007. His recent focus is on bringing the Western Burrowing Owl back to life in California where he also monitors several bluebird trails. He is a BirdLife Species Champion and contributes to several other conservation efforts, being the webmaster for Wintu Audubon Society and the Director of Strategic Initiatives for the Urban Bird Foundation. He is now co-founder of a movement to create a new revenue stream for our National Wildlife Refuges with a Wildlife Conservation Pass.
