The Grey Plover, as this bird is called in England, is only a winter visitor to Central 
America, when it migrates along both coasts on its journeys to and from the Arctic 
Regions. It also wanders inland, and has been observed occasionally on the Missis- 
sippi River in large flocks, and, according to Herrera’, passes through the Valley 
of Mexico on migration. 
In winter S. helvetica travels generally along the coast to the extreme south of both 
continents, migrating either singly or in family-parties, returning generally with the 
black breast of the nuptial plumage partially or fully developed. 
The species is very shy, both in its breeding-haunts and on migration. Its food 
on the sea-shore consists of small crustacea, but during the nesting-season it devours 
berries and locusts, and is said then to be very palatable as food. 
CHARADRIUS.

(1896). 
Charadrius, as at present restricted, includes the Golden Plovers, which differ from 
Squatarola chiefly by the absence of the hind toe. It resembles the latter genus in 
having a black breast during the breeding-season, and is remarkable for its spangled 
golden plumage. ‘The species are not so distinctly Arctic in their choice of nesting- 
quarters, since they breed in the northern temperate zones, as well as in the tundras 
of the north. 
Three species are recognized, two belonging to the Old World and one to America 
in general.
