The Robin-snipe or Gray -back, as the Knot is called by hunters on 

 the Atlantic coast of New Jersey, where it is abundant during- migra- 

 tions, is a regular and somewhat common visitor about the lake shore 

 and at Erie bay, in Erie county, during the spring and fall migrations. 

 In other parts of the state the Knot is seldom seen.

Habitat. Northern portions of Northern Hemisphere , in North America chiefly 

 the northeastern portions, breeding in the high north, migrating in winter to the 

 eastern and middle states, the great lakes and the shores of the larger streams in 

 the Mississippi valley. 



This species I have never met with in Pennsylvania, where it occurs 

 only as a very rare or casual migrant. Mr. George B. Sennett, of Erie 

 city, mentions it as a straggler in his locality. The late Judge Libhart 

 records in his report the capture of a Purple Sandpiper in August (year 

 not given) in Lancaster county. A specimen in the U. S. National 

 Museum was taken many years ago near Philadelphia.
