BAIED SANDPIPER 199 



the Great Lakes, to the coast of New England, whence thej- appar- 

 ently migrate over the ocean to South America. Others migrate 

 southward through the extreme western States. 



Mr. Brewster (1925) says that they "visit Lake Umbagog 

 (Maine) early in September, appearing oftenest during the first 

 week in the month." My Massachusetts dates run from August 7 

 to September 15. E. W. Hadeler records it in his Ohio notes from 

 September 2 to October 11; and Edward S. Thomas has seen it there 

 as early as August 12. It is an abundant migrant in Manitoba ; we 

 collected adults there on July 29; and C. G. Harrold tells me that 

 birds passing through in August and September are practically all 

 juveniles. Professor Kowan refers to it as probably the most plenti- 

 ful wader in Alberta in the first half of September; he has taken it 

 there as late as November 8. J. A. Munro calls it a regular fall 

 migrant at Okanagan Landing, British Columbia; his earliest and 

 latest dates are July 16 and September 18. J. H. Bowles (1918) 

 observed it on the Tacoma Flats, Washington, from July 26 to Sep- 

 tember 5, and says: 



They were found in singles, pairs, or trios, most often associating with the 

 semipalmated plover (Aegialitis semipalmata) when any were to be found. 

 When flying with a company of the other small sandpipers they would separate 

 as soon as the flock alighted to feed, the Baird's going to comparatively dry 

 ground for their food while the others waded about in the water and at the 

 water's edge. They could not have been called common, but from one to three 

 or four were to be found on almost any day. 



John T. Nichols has observed Baird sandpipers on the Pacific 

 Ocean and writes to me as follows : 



August 6, 1926, 52° 19' N., 137° 42' W., three to six birds of this species 

 came about a ship bound southeast for Seattle, flying with and parallel to her 

 course. One, apparently misjudging her speed, was killed by striking the 

 rigging forward. Perhaps the Baird sandpiper is comparatively scarce on the 

 Pacific coast due to an offshore migration route. 



Winter. — According to Prof. Wells W. Cooke (1912) this sand- 

 piper reaches its winter home in September. Chile seems to be its 

 principal winter home, where it has been taken repeatedly in the 

 high mountains at 10,000 to 12,000 feet and once at over 13,000.
