Range. - A common Old World species, but regarded as rare in eastern North America and northern Alaska.

A bird of slighter build, but similar coloration to the Knot; smaller (length eight inches) and with a slightly decurved bill. Until within recent years, eggs of these birds were rarely seen in collections, and I believe they have not yet been taken in this country, although a few pairs nest along our Arctic coast. Their eggs are very similar to those of the Red-backed Sandpiper, but average somewhat larger. Size 1.50 x 1.05. Data. - Kola, northern Lapland, June 15. 1898. Four eggs laid in a grass-lined hollow in the ground. Collector, J. Ramberg.
