While this species is to be found in the state throughout the 

 year, it is by no means a resident of one particular locality for this 

 time. It is a fairly common migrant and winter resident along the 

 coast, while in the interior it is a summer resident and breeder on 

 some of the lakes in the northern part of the state.

This species is quite a common resident along such parts of the 

 coast as belong to the Canadian Fauna, and also occurs as a sum- 

 mer resident on some of the interior lakes. In the Alleghanian 

 Fauna it occurs as a migrant, or winter resident. For notes on 

 the breeding of this species along the coast see Knight, The Auk, 

 Vol. 12, p. 387.
