Some birds migrate E in broad front across taiga. Southward migration takes place in large folocks, and at night. Some Alaskan breeders fly 4500 km nonstop across Pacific Ocean to Hawaiian Is in Aug. Arrival in Fiji in early Sep, New Zealand in Oct. E Africa and E Asia probably reached by overland migration across W Siberia.Status and Conservation.Not globally threatened.
