1 The only American specimens of this form that I have seen are five from Kadiak (breeding birds) and 

 the same number from Quebec (winter specimens). It cannot, of course, be stated where the latter came from, 

 their migration from the northwestward or from the eastward (possibly Newfoundland) through the St. 

 Lawrence Valley being equally possible.
