Semipalmated Sandpiper 117 



ashy aud streaked. Young birds are very similar to the summer 

 adults, but have the belly spotted with black, not with a continuous 

 black patch. 



Distribution. — Breeding chiefly on the Barren Grounds from 

 Hudson Bay to northern Alaska and Siberia, migrating chiefly along 

 the coasts to winter in south California, the Gulf and South 

 Atlantic States. 



A very rare migrant in Colorado, only twice recorded. There was 

 an adult in winter dress in the Maxwell collection supposedly from 

 Colorado, and W. G. Smith obtained two examples at Loveland, April 

 28th and May 9th. 



Genus EREUNETES. 



Bill about as long as the tarsus, rather stout for the family ; toes 

 bagally webbed and broadly margined ; in other respects like Pisohia. 



Two North American species closely allied to one another, comprise 

 this genus. Both are recorded from Colorado.

Description. — Adult in siunmer — Above, including the upper tail- 

 coverts ashy-brown with dusky centres and some tawny edges ; central 

 tail-feathers and primaries plain dusky ; below white with a few small 

 dusky streaks on the lower-neck and chest ; iris dark brown, bill and 

 legs greenish-black. Length 5-5; wing 3-65; tail 1-5; culmen -80; 

 tarsus -75. 



In winter the upper-parts are nearly plain ashy-grey, and the spots 

 on the breast faint or obsolete ; young birds have a slight wash of 

 buffy but no spots on the breast, and a good deal of white edging on 

 the scapulars. It can be distinguished at once from P- minutilla, 

 which it closely resembles in plumage by its basally- webbed toes. 



Distribution. — Breeding from Labrador and Hudson Bay to northern 

 Alaska, south through the United States east of the Rocky Mountains, 

 to winter in the Gulf States, West Indies and eastern South 

 America. 



This Uttle Sandpiper is not unconmion on migration in eastern 

 Colorado, chiefly on the plains but ranging up as high as the naountain 

 parks ; it has been noticed by Carter in South and Middle Parks. It 

 reaches Colorado about the end of April or beginning of May, and has
