The White Pelican (Pelecanus erythrorhynchos) population breeding at Lavalle Lake, Prince Albert National Park, has increased since 1938. Pelicans fledged increased from 700-1500 between 1938 and 1940 to a high of 2696 in 1976. Nesting islands decreased from three to one but sub-colonies increased from 3 to I5 over that period. Nesting shifted from treeless areas to areas with an overstory of coniferous forest. Most foraging during the breeding season was outside the park at Montreal Lake.
