 green band on each side, uniting and blackening on the nape; under

 and Honduras. 



Nest, on ground in grass. Eggs, 6-12 (16-1.8, Ball.); buff or green- 

 ish; 1.75 by 1.30. 



Common migrant; also, winter resident; may be locally a rare sum- 

 mer resident in northern part of the State. 



Some winters the Green-winged Teal remains on Lake Michigan and 

 the larger streams. With the first bird wave, usually in February, they 

 may be noted returning from the south. In 1887 they were reported 

 from Terre Haute, January 30, 'and next, February 5 (Evermann). 

 From Vincennes in 1888, March 5; in 1889, February 20. They pass 

 northward as the ice melts, but sometimes they reach the northern 

 part of the State while the streams and lakes are still locked in ice. 

 Mr. Ruthven Deane informs me the first were shot at English Lake 

 March 18, 1886. Six were shot there March 17, 1889. A small flock 

 seen February 27 and 28, 1892. Noted March 11, 1894. They do not 

 linger long in the southern part of the State, and most of them must 

 have left our northern marshes before April 1. I have taken it at 

 Brookville April 3 (1883). It has been taken in Carroll County April 

 8 (1885, Evermann), and at Kouts April 12, 1895 (Parker). 



It is not known to breed in the State. It formerly did to a limited 

 extent in Illinois (Nelson's Birds N. E. 111., p. 140), and is reported 

 as breeding at St. Clair Flats and St. Joseph, Mich. (Cook, Birds of 

 Mich., p. 39). Although Kennicott found it to be very rare 

 on the Yukon, its breeding range extends far north. Turner 

 found it common in Alaska and among the Aleutian Islands, where 

 it is resident (Contr. to Nat. Hist, of Alaska, p. 132). Breeds com-
