ico, Michoacan and Jalisco ; common also in the Bahamas 

 and rare in Cuba, Jamaica and Honduras. It has been 

 recorded on the islands of Carriacou, Grenada and Toba- 

 go, of the Lesser Antilles. 



It is one of the most abundant ducks throughout the 

 southwestern United States during winter. It is a hardy 

 duck and in general remains as far north as it can find open 

 fresh water. Thus it winters in western Montana (Great 

 Falls), central Utah, southern Nebraska, southern Iowa, 

 central Illinois, central Indiana (rarely Lake Michigan), 

 western New York and Rhode Island. It is accidental in 

 Massachusetts in winter, and one was found at Halifax, 

 Nova Scotia, Jan. 14, 1890. The principal winter home in 

 the Mississippi Valley lies south of 37° latitude. 



Spring Migration. — The green-winged teal is one of the 

 early migrating "river ducks," but not quite so early, by 

 about five days, as the mallard. Along the Atlantic slope 

 it passes north of its winter home in early March, and the 

 average date of its arrival in southern Pennsylvania is 

 March 16 ; southern Connecticut, April 6 ; Montreal, Can- 

 ada, April 27 ; Prince Edward Island, April 26. 



The average date of the first arrivals in central Mis- 

 souri is Feb. 26; central Illinois, March 7; English Lake, 

 Ind., March 15; Keokuk, la. (average for twelve years), 

 March 3; central Iowa (fourteen years), March 11; Her- 

 on Lake, Minn, (six years), March 24 (earliest, March 6, 

 1887.) In its migration along the eastern border of the 

 plains the green-winged teal is noted at Onaga, Kans., 

 March 8; northern Nebraska, March 12; central South 

 Dakota, March 20; northern North Dakota, April 6; 

 Aweme, Man., April 16, and southern Saskatchewan, 

 April 19. These dates indicate the rather slow rate of
