and Geese at such times. They usually fly low after landing, sweeping 
slowly over the ground, apparently looking it over, generally standing 
motionless for quite a while after alighting, which, owing to their 
general color approximating so closely to the withered grass, renders 
it difficult at times to perceive them. . . . The only note I ever heard 
them make is a kind of squeak, very much like one of the cries of 
Wilson's Tern (i Sterna hirundo), only finer in tone." (Mackay, Auk , 
1892, 16-21, 1893, 79; 1894, 75; 1897, 212; 1899, 180.) The Eskimo 
Curlew is now believed to be on the verge of extinction. The latest 
records appear to be Newburyport, Mass., Aug. 27, 1908 (Thayer, J. E., 
Auk, 1908, 77) and Waco, Nebr., Mch. 22, 1911, two females (Aug. Eiche). 
A specimen of the European Curlew (. Numenius arquatus ) said to 
have been taken on Long Island in 1853, is in the New York State Museum 
at Albany. (Dutcher, Auk, IX, 1892, 390.) 
The Whimbrel {267. Numenius phceopus), an Old-World species, is 
of accidental occurrence in Greenland and has been once recorded from 
Nova Scotia. 
27. Family Charadriid^e. Plovers. (Figs. 42c, d; 43c, d.) 
The seventy-five odd species contained in this family are, as a 
whole, of less boreal distribution than the Snipes, and during the nest- 
ing season are distributed throughout the world. Only eight species 
are found in North America. Their habits in a general way resemble 
those of the true Snipes, but their much shorter, stouter bills are not 
fitted for probing, and they obtain their food from the surface. Probably 
for this reason several species are as frequently found on the uplands 
as near the shores.
