This is the most swift and graceful of this family in flight. Similar to the last species, but the central pointed tail-feathers extend eight or ten inches beyond the others. It is more often found in the lighter phase.
Nest.—Their eggs are either laid on the bare ground or in a slight depression, scantily lined with grass (2.10 × 1.50).
Range.—Arctic America; south in winter to South America.
