Satellite Tracking of Migratory and Ranging Behavior of Immature Great White Pelicans

Waterbirds, 2002
Abstract Because migration routes and stopover sites of the endangered Palearctic migratory Great White Pelican (Pelecanus onocrotalus) are poorly known, satellite tracking was used to map spring and autumn migration routes, stopover sites and ranging areas in Europe, Israel and Africa.

Importance of Great Salt Lake to Pelagic Birds: Eared Grebes, Phalaropes, Gulls, Ducks, and White Pelicans

2020
Utah’s Great Salt Lake (GSL) is so saline that the only invertebrates that survive in the open water are brine fly larvae and brine shrimp. In the absence of competition from other invertebrates, they are incredibly abundant. Only a few avian species can take advantage of their abundance because a bird cannot eat them without also ingesting salt ...
