Green-winged Teal 41 



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 Ailcen collection 

 taken at Falcon on May 3rd, and Horsey and Rockwell include it as 

 a 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 GadwaU 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.
