April, occasionally to the end of the month (April 28, 1904, 

 Kansas City, Bryant). Those seen in April are generally in 

 pairs. In fall migration they reach us early in October, are 

 common from October 10 to November 20; some hnger on the 

 southeastern waters well into winter. 



Some writers use the term "wintering " when a species is seen 

 in every month of winter, but this is misleading. Many birds 

 stay with us until the first part of January when the severest 

 period of winter begins, are gone for over a month, but return to 

 us before the end of February, at which time the strength of win- 

 ter is broken and the ice of the rivers has moved out.

In Missouri the Green-winged Teal is a very common transient 

 visitant. It returns to the southeast soon after the middle of 

 February, to the marshes of north Missouri and the western part 

 of the state about the first of March. The bulk is present from 

 March 10 to 25, but the last has not left the state before a month 

 later. In autumn the first begin to reappear between September 

 15 and 22 and from the end of the month to the middle of No- 

 vember they may be found in many parts of the state. The}^ are 

 mostly all gone by the middle of December, but in mild winters 

 a few may be found in January.
