Hich. — The whole of North and South Auierica, breeding north of tlie United

This, the smallest of our Sandpipers, occurs in Pennsylvania only 

 as a transitory visitor in the spring and fall migrations. According 

 to my experience, it is rare in spring, but quite Irequently found in 

 the autumn, at which time it is often seen in company with other spe- 

 cies of its family. Sometimes these birds are found about our rivers 

 and ponds in good sized flocks. Near West Chester, about six years 

 ago, in the latter ijart of August, an acquaintance of mine found a 

 flock of probably one hundred feeding on the muddy bottom of a mill- 

 dam from which the water had been allowed to escape. 



Food. 



In my notes I find that no records appear of food-materials of these 

 birds, although 1 have obtained several in Pennsylvania and killed 

 many along the Atlantic coast and elsewhere. Nuttall tells us that 

 '' for the discovery of their i'ood their flexible and sensitive awl-like 

 bills are probed into ihe mire, marshy soil, or wet sand, in the manner 

 of the Snipe and Woodcock, and in this way they discover and rout 

 from tiieir hidden retreats the larvce and soft worms which form a 

 principal part of their fare. At other times they also give chase to 

 insects, and pursue their calling with amusing alacrity."
