Migration. — In common with many other hawks, the roughlegs 

 sometimes migrate in large loosely organized flocks. Magee (1922) 

 reports that "the line of greatest hawk migration between the east- 

 ern portion of the Upper Peninsula of Michigan and Canada is at 

 Whitefish Point." According to Fleming an immense flight occurred 

 in the latter part of October 1895 in the vicinity of Toronto, On- 

 tario, and the birds continued to pass in decreasing numbers until 

 December 5.
