    Breeding: Clutch size: 4-10 buffy eggs with large brown spots; laid in late May and early June. Incubation: 21-23 days. Young fledge 10 days after hatching.
    Nest: Well-concealed depression in the ground; lined with dry grasses, leaves, and twigs. Nest often under low branches of spruce, jack pine, or white pine; in brush; in deep moss; or adjacent to a tree trunk or stump.

Management Considerations: Generally, preservation of large tracts of coniferous forest. Recreational incursions into remote areas are a disturbance factor. This species has cyclic population swings.
