Breeds in muskegs and freshwater marshes in open boreal forests and forest/tundra transition habitats. Often nests in drier, more densely vegetated habitats than sympatric Greater Yellowlegs (Tibbitts and Moskoff 1999). Nesting habitat is typically a combination of shallow wetlands, trees, shrubs, and open water. Forages in boreal forest wetlands, saltmarsh ponds, and intertidal areas.
