The American white pelican is a large aquatic soaring bird from the order Pelecaniformes. It breeds in interior North America, moving south and to the coasts, as far as Costa Rica, in winter. Adults are usually silent. In aggressive and sexual encounters at the colony site, they emit frequent low, brief grunts. Chick embryos squawk before hatching to express discomfort if conditions get too hot or cold. The begging calls (described as a "whining grunt") of hundreds of older young in the colony can be raucous. Here is a link to their grunts.
