DISTRIBUTION.

‘Deducting these, there are 58 species of shorebirds that belong to 
the regular avifauna of North America north of Mexico. Not all of 
these, however, occur in the. United States. The sharp-tailed sand- 
piper is a regular migrant through Alaska, but is not found elsewhere 
in North America. The Pacific godwit, bristle-thighed curlew, and 
Pacific golden plover breed in Alaska and migrate thence to ‘Asia and 
the Pacific islands. The ringed plover breeds in northeastern North 
America and migrates to Europé. The turnstone breeds in both 
northeastern and northwestern Arctic America, but migrates to 
Europe, Asia, and the Pacific islands without coming regularly to 
the United States; while the Aleutian and the Pribilof sandpipers 
both breed and winter in Alaska. A further deduction of these 8 
species leaves 50 species which regularly visit the United States 
during some part of the year. 7 . . 
The shorebirds as a group are far northern breeders. The ma- 
jority of them breed in the region of the Arctic Circle, and several 
range north to the known limits'of land. The majority do not breed 
so far south as the United States, and hence are known there only as 
migrants, or in the winter season.
