In the shortness of its bill this genus resembles Aphriza, but differs from it in wanting 
the hind toe. In appearance the species of Ochthodromus are very similar to the 
Sand-Plovers (Zgialitis), but are distinguished from the latter by their heavy bill. 
Hight species are recognized, of which two are resident in Australia and New Zealand, 
and the other six breed in the temperate regions of the north, and migrate south in 
winter. One of them, O. wilson, is peculiar to the New World.

Wilson’s Plover nests on the southern Atlantic seaboard of the United States, and 
occasionally straggles northwards to Long Island and Nova Scotia. On the western 
side of North America it is found in California only, nesting abundantly in the southern 
portion of that State!’. Salvin also found nests on Grassy Cay, one of the islets off 
the coast of Belize®*®. 0. wilsoni appears to migrate along both shores of Central
