256 LONG-BILLED RUNNING BIRDS. 



ling are the only birds with which, because of their 

 somewhat similar changes of colour, the Knot may be 

 confounded. 



DUNLIN— 8 inches; central tail-featheis longer than the 

 others, whilst the tail of the Knot is square at the end ; 

 rump brown, hut whitish, flushed with chestnut, in the 

 Knot; form slighter in the Dunlin. In summer the 

 Dunlin is infallibly recognised :by its black stomach- 

 patch. 



CURLEW- SANDPIPER— 8 inches; rump white at all 

 times, and bill clearly curved downwards. 



SANDERLING— 8 inches. Lacks the white or whitish

 length to the head, blackish ; legs blackish. Winter : 

 light ashy-gray above, white below. Spring and 

 autumn migrant.

 the water-line, and behaving generally as they behave,
