482 THE BIRDS OF MANITOBA THOMPSON. 



as the rivers are open ; not so frequently obtained in the autumn, prin- 

 cipally, I think, because it confines itself to the large lakes, seldom 

 visiting the creeks or sloughs at that season ; it remains until it is fro- 

 zen out; in 1884, first seen April 16 (Xash, in MSS.).
