SNIPES AND SANDPIPERS 243 
With the Plovers they constitute the great group known as Shore 
Birds or Bay Birds, and with few exceptions they are rarely found far 
from the vicinity of water. Generally speaking, they are more abundant 
on the coast than in the interior, but many species are quite as 
numerous inland as they are near the sea. Asa rule, they migrate and 
pass the winter in flocks, but they are not gregarious during the nesting 
season. 
Their long bills serve the purpose of both probes and forceps. Most 
of the species probe the soft mud for food, while some are known to 
have the power of moving the upper mandible independently of the 
lower one, curving it at the tip as one would a finger. 
Snipes are not supposed to be song birds, but during the breeding 
season many species are highly and peculiarly musical, and at other 
times of the year they utter characteristic whistles, to an imitation 
of which the birds are quick to respond.
