Blackfeet Indian Reservation Professional Review and Guide
"Any birding trip on the Blackfeet Reservation begins in Browning. In town look for House Sparrow and Black-billed Magpie. Also stop in at the Museum of the Plains Indian, open from June through September, on the north end of town. North and east of town, the Browning Landfill is seldom visited by birders but offers good opportunities for viewing gulls (Ring-billed Gull, California Gull) and corvids (American Crow, Common Raven) besides Horned Lark and Northern Shrike during migration.
Along U.S. 2 between Browning and East Glacier, the Blackfeet Potholes harbor a diversity and abundance of birds. Species likely to be seen here include Horned Grebe, Eared Grebe, Mallard, Northern Shoveler, American Wigeon, Canvasback, Redhead, Ring-necked Duck, Lesser Scaup, Ruddy Duck, Northern Harrier, Virginia Rail, Sora, American Coot, Common Snipe, Wilson’s Phalarope, Black Tern, Barn Swallow, Sprague’s Pipit, Western Meadowlark, and Yellow-headed Blackbird."
