Agassiz National Wildlife Refuge

small state map showing location

Middle River, Minnesota


Agassiz National Wildlife Refuge was established in 1937 and occupies part of the bed of glacial Lake Agassiz in northwestern Minnesota. Agassiz is located within the Mississippi Flyway and is one of over 500 refuges in the National Wildlife Refuge System which extends from Canada to Mexico.

Agassiz has been designated a Globally Important Bird Area for its efforts to conserve wild birds and their habitats. The refuge hosts up to 40,000 ducks, 14,000 geese and 1,000 Sandhill Cranes during migration. It also hosts one of the world's largest colonies of Franklin's Gulls (about 25,000 to 50,000 nesting pairs), 1,500 Black Terns and 3-5,000 non-breeding American White Pelicans. Le Conte's Sparrow is common and the Clay-colored Sparrow is abundant during breeding season. Other breeding birds seen include Nelson's Sharp-tailed Sparrow, Bobolink and Yellow Rail.

This list contains 287 species which have been observed on the refuge. The information is obtained from refuge personnel and other interested birders, like yourself. Visiting birders are encouraged to share their rare or unusual sighting with refuge staff!
