of this species, and can positively say that they' are a rare spring 

 migrant, and a common fall visitant. It is very hard to distinguish 

 them in the fall plumage from the young of Totanus flavipes. I 

 have one in the breeding plumage taken at South Chicago on the 

 Calumet River in April, 1890; also one in the light plumage taken 

 at Mud Lake, September 23, 1893. Mr. J. G. Parker, Jr., has a bright 

 female taken from a flock of four at Mud Lake, July 25, 1893; also 

 a young bird from the same locality. On August 24, 1895, Mr. 

 J. F. Ferry of Lake Forest, 111., and myself shot four Stilt Sandpipers 

 from a flock of fifty or more at Liberty ville, 111." (The Auk, Vol. 

 XIII, 1896, p. 180. ) 



Kumlien and Hollister say (Birds of Wisconsin, 1903^. 44): "It 

 is a migrant and doubtless a former summer breeder to a limited 

 extent. * * * * During the seventies they were rather common 

 about Koshkonong, especially during the latter part of July, August, 

 and well into September. We have taken young barely able to fly, 

 readily running them down. These had the head and upper neck 

 still in the natal down, and if they were not hatched at Lake Kosh- 

 konong, certainly they could have come but a short distance." 

 This is interesting from the fact that the limit of its supposed breeding 

 range is very much farther north. It will be noted, however, that 

 there is no record of the nest and eggs having been taken in the 

 state.
