in the fall about the last days of September. Mr. E. W. Nelson 

 says, in his "Birds of Northeastern Illinois" (1876) : "Not a 

 very rare summer resident." His report would also indicate 

 that these ducks nested in this region at that time, for he says : 

 "It nests about the borders of marshes and prairie sloughs." 



The range of this species includes North America from the 

 Arctic Ocean south to Guatemala, and it breeds nearly throughout 

 its range.

Mud Teal. 



A common migrant, and is said to winter in the southern part 

 of the state. Our records show the earliest spring arrival to 

 be early in March and the first fall arrival to be September 26. 

 Mr. E. W. Nelson says that it "breeds sparingly. I have known 

 of a few instances of its nest being found, and have myself ob- 

 served several pairs of the birds in this vicinity during the breed- 

 ing season." Mr. Robert Ridgway says :* "Although stated by 

 Kennicott to breed in the northern part, (of Illinois) there appears 

 to be no recent record of its doing so." As Mr. Kennicott died 

 May 13, 1866, his notes regarding this species must have been 

 made previous to that time. Mr. Ridgway also records in his 

 "Catalogue of the Birds Ascertained to Occur in Illinois,"! the 

 following note: "Resident, but most abundant during migra- 

 tions : breeds only in the prairie districts, and winters chiefly in 

 the lagoons of the heavily timbered bottoms." 



The Green-winged Teal breeds chiefly north of the United 

 States, but its geographical range includes the whole of North 

 America.
