Open, generally barren country, avoids forests (Beason 1995). In B.C., breeds at elevations up to 2,800 m in open space uncluttered with trees, shrubs, or even tall forbs, typically above timberline in mountainous regions (Campbell et al. 1997). In the Yukon, nests on dry alpine tundra, often near exposed rocky areas or stony heath; or on dry tundra in coastal areas, often on hilltops or ridges where gravel and rock is exposed (Salter et al. 1980, Alexander et al. 2003).
