The Swan River National Wildlife Refuge (NWR) is home to many species of wildlife and provides important habitat for year-round and migratory species.

  • Waterfowl


    The Swan River NWR provides nesting habitat for 23 species of waterfowl, with the most common species being mallard, cinnamon teal, blue-winged teal, and common goldeneye. Other common species include: wood duck, ring-necked duck, bufflehead, common merganser, and lesser scaup.

  • Wading Birds and Grebes

    Great Blue Heron 150x118

    Annual flooding of the Refuge in the late spring and early summer provides excellent habitat for marsh and water birds. Careful observers may spot sandhill cranes, American bitterns, soras, great blue herons, or pied-billed, red-necked, or horned grebes.

  • Raptors


    Coniferous and deciduous forests on the Refuge offer excellent resting and loafing sites for many raptor species.  Northern harriers, Swainson's hawks, red-tailed hawks, and great horned owls are commonly observed.  Bald eagles have successfully nested on the Refuge for many years.  The eagles arrive in February to begin nesting and usually fledge one or two eaglets in mid-May.  Transient eagles also use the Refuge; up to eight eagles have been spotted at one time.

  • Grizzly Bears


    The Swan and Mission Mountain Ranges provide important habitat for the grizzly bear.  The Refuge serves as a key corridor between these two systems.  Grizzly bears are occasionally observed on the Refuge in the spring and summer.

  • Other Mammals
