[243.] Trlnga alplna Linn. [539.] 



Dunlin. 



Hab. Europe, accidental in North America. 



The Purre or Dunlin has a wide distribution in the northern parts 

 of the Old World. By far the most abundant of the British Sand- 

 pipers, being equally distributed in the marshes, on the borders of 

 mland lakes, and along all the seashores from the most northern 

 island to the southern coast of England. The birds usually feed in 

 great numbers after the retiring tide, or on the oozy flats of soft sand 

 or mud, which cover the low-lying shores of the islands. In the spring 

 they separate into pairs, retiring to the marshes and shores of inland 

 lakes and muirs to breed. Their nests are made at the foot of a small 

 bush or tuft of grass, often so concealed as to be very difficult to find. 

 A few bits of grass or moss form the lining of the slight cavity, in 

 which usually four eggs are deposited. They vary in ground color 

 from greenish-white, yellow, gray and often inclining to light blue • 

 they are spotted and blotched irregularly with reddish-brown ; the 

 spots becoming more numerous toward the larger end. Four speci- 

 mens measure 1.54x1.14, 1.53x1.08, 1.59x1.15, 1.51x1.10.
