368 The IVater-fowl Family 



Closely resembling the forms just described, 

 the habits of the Pribilof sandpiper are similar to 

 its relatives'. 



On the Pribilofs this bird is abundant and 

 tame, living on the moss-covered tundra, on the 

 shores of the pools, and in late summer along the 

 beaches. The young leave the nest as soon as 

 hatched and are well protected by the resemblance 

 of their upper parts to the colors of the vegetation 

 around. When they are approached, the mother, 

 feigning lameness, attempts to draw the intruder 

 away, while the young, flat on the ground with 

 outstretched necks, will allow themselves to be 

 touched rather than betray their location by a 

 movement.
