72 LIMICOL^): Shore-Birds 



BAIRD SANDPIPER 



(241. Pisobia bairdi) 1\ in. 



Upper parts rusty and gray, feathers dusky-streaked cen- 

 trally on head and fore-back, spotted on wing-coverts; chest 

 buffy, dusky-speckled and streaked; breast and belly white. 



Except for larger size and brown wash of chest this bird is 

 easily confused with the Least Sandpiper. 



Habitually feeds and rests back from the water's edge, where 

 it associates with Snowy and Semipalmated Plovers. 



LEAST SANDPIPER 



(242. Pisobia minutilla) 6 in. 



Back black, widely edged with rusty; white below, chest dark 

 gray with dusky shaft-lines. Rusty edging of back is nearly 

 absent in winter, when chest-band is less distinct. 



In any plumage the dark chest-band is conspicuous and 

 distinguishes the species from the Western (of nearly equal size.) 



WESTERN SANDPIPER 



(247. Ereunetes mauri) 6| in. 



Upper parts rusty; back feathers with broad black marks, and 

 gray edges, arranged in " streaky" pattern; white below, whole, 

 head, neck, chest, and sides finely black-streaked. A white stripe 

 along wing shows in flight. 



In winter, gray above, white below, with chest gray-washed, 

 or faintly streaked. (Compare with Least Sandpiper, which has 

 dark gray chest, dusky-lined, at all seasons.) 



SANDERLING 



(248. Crocethia alba) 8 in. 



Head, neck, and chest rusty, with fine dusky spotting; rusty 

 predominates on back, where feathers show black centrally and 

 gray edges; primaries black; a white wing-stripe shows in flight. 



Winter: Ashy above, with darker central streaks; white below. 



In summer dress the Sanderling appears conspicuously red- 

 dish. White belly distinguishes it from Knot and Dowitcher.
