maica and the Bermudas. The winter range extends to 

 the southern end of Lower California, to Mazatlan and 

 the City of Mexico. In northern Mexico the species is 

 common through the winter, and birds have been found 

 paired in May, the late date indicating that they intended 

 to remain and breed. Thence it extends commonly to 

 Utah and Oregon, rarely to Washington and British 

 Columbia. 



Spring Migration. Only a few notes on the migration 

 of this species have been recorded. The average date 

 when the first spring migrants reach southern Iowa is 

 March 18 (earliest, March 10, 1896), it thus being one of 

 the earlier ducks in this part of its range. It reached 

 Heron Lake, Minn., April 1 (earliest, March 17, 1886) ; 

 Loveland, Colo., March 6, and Terry, Mont., about April 

 1. The first migrant was seen at Aweme, Man., April 23, 

 1898, and at Indian Head, Saskatchewan, April 18, 1892, 

 and April 24, 1904. Eggs have been secured at St. Clair 

 Flats, Ontario, about May 30; in western Minnesota, June 

 14, 1879; northern North Dakota, June 15, 1901; Mani- 

 toba, June 5, 1894; Crane Lake, Saskatchewan, June 9, 

 1894; Nevada, May 29, 1868, and incubated eggs in Los 

 Angeles County, California, April 16. 



Fall Migration. The first arrived at the southern end 

 of Lower California Sept. 27, 1887; in northern New 

 Mexico the species was abundant the last days of Sep- 

 tember, 1904. The average date when the last left cen- 

 tral Minnesota was Nov. 14.
