Green-winged Teal 4] 
The only definite account of its nesting is that of Coues, who found 
it with young birds and several other species of Duck on a small lake 
on the southern edge of North Park, probably about 8,000 feet, shortly 
after the nesting-season ; there is an adult male in the Aiken collection 
taken at Falcon, on May 3rd, and Hersey and Rockwell include it as 
@ summer resident at Barr. It was seen on the San Luis Lakes in 
June by Warren. 
On migration it was noticed by W. G. Smith at Loveland, March 
10th to 13th, and seen by Carter in Middle Park (Cooke), while Sullivan 
reports it as plentiful in the fall but scarce in the spring at Grand 
Junction (Rockwell). Felger states that it is not uncommon in winter 
at Barr. 
Habits.—Like the Mallard and Gadwall this is a shoal- 
water Duck, preferring the edges of lagoons and grassy 
lakes to large pieces of water, and feeding chiefly on 
vegetable matter, so that it is generally good eating. 
Goss states that they rob Canvas-back and other 
deep-water Ducks of the vallesneria grass which grows 
in deep water, and which they cannot procure for them- 
selves as they do not dive. The eggs, 6 to 12 in number, 
are pale buff to nearly white, and measure 2°05 x 1°45.
