Complementary to the fall southward flight is the northward post- 

 breeding wandering, which in no species is more strikingly illustrated 

 than with these birds as indicated by the returns from young banded 

 on June 16, 1923, at the colony at Sandy Neck, Barnstable, Massa- 

 chusetts. Data from these birds have been secured from points in 

 New Hampshire, Vermont, Maine, Ontario, and Quebec, through the 

 months of August and September while one (Biological Survey num- 

 ber 233871) was recovered at Amherst Island, Ontario on November 1, 

 1923. Several returns have come from points on the St. Lawrence 

 River, the most northerly being number 233847, recovered on Sep- 

 tember 9, 1923, within a few miles of the city of Quebec. 



That all birds from any colony do not undertake these wanderings 

 to the North is illustrated by returns from other birds, banded at the 

 same time and place and which evidently moved directly south. 

 Thus number 233601 was returned from Napanoch, New York, on 

 August 27, 1923; number 233764, from Now Holland, Pennsylvania, 

 on August 22, 1923, and number 233845 from the mouth of the White 

 Oak River, North CaroHna, on October 9, 1923. The wintering 

 grounds of the bulk of the New England birds may possibly be indi- 

 cated by the return record of number 233845, which was killed in the 

 cypress swamps in northern Lee Country, Florida, on December 25, 

 1923, and by number 233743, which was killed in Hanover County, 

 Jamaica, early in November, 1923.
