More northern portions of northern hemisphere, the northern limit 

 of its breeding range inosculating with the southern portion of the 

 breeding range of ^. liornemannii ex'd'qjes (Ungava to western Alaska); 

 breeding southward to islands in Gulf of St. Lawrence;^ in winter 

 south to more northern United States generally, irregularly and more 

 rarely to Virginia (Alexandria Co.), northern Alabama (Stevenson), 

 southern Ohio (Hamilton Co.), southern Indiana (Franklin, Decatur, 



^ Forty-six specimens. 



^ Thirty-four specimens. 



Specimens from Euro^je and northeastern Asia average a littl ; larger than those 

 from North America, although the difference is slight and with more nearly equal 

 series, perhaps even less than that indicated by the following averages:

The series of European specimens is much too small to afford satisfactory compar- 

 ison with North American birds. They show certain differences of coloration, which 

 may or may not prove to be constant, and comparison with larger series is therefore 

 very desirable. 



Said to breed in Nova Scotia and New Brunswick; also, according to Hatch (Birds 

 of Minnesota, p. 299), in Vermont and northeastern Minnesota.
