 the season of migration. It has a wide breeding range through- 

 out the United States and British America. At the St. Clair 

 flats it has often been seen at midsummer, but so far I have no 

 record of its nest or eggs having been found there. It seems 

 rather tender, and is one of the first to retire to the south in the 

 fall.

This dainty little duck visits us in considerable numbers 

 in April ; and in September is again seen while on its way south. 

 It was found by Professor Macoun breeding in Grand Valley 

 near the Assinaboine, and most likely does so in intermediate 

 districts, though to what extent is not at present known. It is 

 one of the first to return from the north, and is eagerly sought 

 for at the shooting stations on account of the delicacy of its flesh.
