A Wonderful Bird Is the Pelican



American White Pelicans (Pelecanus erythrorhynchos) breed in the Northern Plains and in Canada, according to Lives of North American Birds, by Kenn Kaufman, and winter along the California and US Gulf of Mexico coasts. Their large size (wingspan is 9’), notable in the above photo by Dick Malnory, and distinctive bill make them easy to recognize and the subject of cartoons and parodies such as this one by Dixon Lanier Merritt:

“A wonderful bird is the pelican, 
His mouth can hold more than his belly can,
He can hold in his beak
Enough food for a week.
I’m damned if I know how the hell he can!”

That famous bill has some interesting characteristics. It allows for catching and storing fish and is sufficiently sensitive that the birds can locate fish at night by touch. The bill allows water to be drained before the fish is swallowed. According to The Sibley Guide to Bird Life and Behavior, pelicans exercise the pouch to maintain elasticity. And during breeding season the pouch become brightly colored.


The next photo, taken by Jack Chiles, shows an American White Pelican seen at Hagerman National Wildlife Refuge in springtime. Jack notes that the bird is showing the horny knob on the upper mandible displayed by both sexes during the breeding season. These knobs are believed to be a target for other adults when they arrive at the communal breeding grounds and fight for territories, Once eggs are laid, the knobs fall off.



Another interesting aspect of the American White Pelican is their coordinated fishing. They can be seen swimming in one or more lines, “herding” fish into the shallows for an easy catch. Most often found in fresh water, they eat primarily fish and crayfish.


These magnificent birds will be passing through HNWR during the next few weeks on their way to their winter grounds. On the Tuesday Bird Census for October 10, 2017, 1034 American White Pelicans were listed, but only 54 on October 17.   There are surely many more to come this Fall!

Pelican Update



In September, 2012, we blogged about the Fall migration numbers of the American White Pelican at Hagerman National Wildlife Refuge.   Let's take another look, two years later.  The following entries have been excerpted from the  Hagerman NWR Weekly Bird Census  by Jack Chiles, Master Naturalist:

2012
Sept. 4 - 0; Sept. 11 - 0; Sept. 18 - 0; Sept. 25 - 1000
Oct. 2 - 54; Oct. 9 - 10; Oct. 16 - 260; Oct. 23 - 25
Oct. 30 - 7
Nov. 6 - 127; Nov. 13 -300; Nov. 20 - 100; Nov. 27 - 25

2013
Sept. 3 - 3; Sept. 10 - 3; Sept. 17 - 4; Sept. 12 -24
Oct. 1 - 2080; Oct 8 & 15- shutdown/no census;  Oct. 22 - 1250; Oct. 29 - 1500
Nov. 5 - 75;Nov. 12 - 56; Nov. 19 - 50; Nov. 26 - 7



Thanks to Jack’s reports we have a picture of the swings in population of the American White Pelican at Hagerman NWR during the fall migration.  Pelicans were sighted circling overhead at HNWR last weekend, so the 2014 fall migration is now underway.
