54 BIRDS OF COLORADO. 



137. Anas americana. Baldpate. 



Summer resident; tolerably common, locally; in migration, 

 commonly distributed all over the State and occasionally in the 

 fall migration is locally abundant. Breeds mostly in the north, 

 but a few remain behind to breed on the prairies of Kansas and 

 eastern Colorado, while Dr. Coues found them breeding in large 

 numbers in North Park at an altitude of about 8,000 feet. (B. 

 N. O. C. II. 1877,51.) 



139. Anas carolinensis. Green-winged Teal. 

 Summer resident; common, locally; in migration, abund- 

 ant. One of the earliest ducks to migrate in the spring and on 

 the plains one of the most abundant. The bulk breed farther 

 north and it is a rare breeder on the plains, but among the 

 mountains and mountain parks it is not uncommon through the 

 summer. Henshaw found it in the San I,uis Valley breeding 

 in considerable numbers June 24, but not yet through laying. 

 Morrison reports its breeding near Fort Lewis in southwestern 

 Colorado, and Kellogg found it as a common summer resident 

 of Estes Park. 



140. Anas discors. Blue-winged Teal. 



Summer resident, common; in migration, abundant. What- 

 ever has been given above concerning the Green-winged Teal 

 would apply equally to the Blue-winged. 



141. Anas cyanoptera. Cinnamon Teal. 



Summer resident; common. A western species abund- 

 ant over all the country west of the Rocky Mountains. Many 

 cross the range and are found along the eastern foothills; farther 

 east they are rare. H. G. Hoskins writes that he found one at 

 Beloit, near the eastern boundary of the state, on October 27, 

 M895, and they have several times been taken in Kansas. There 

 is no record of their breeding far out on the plains of Colorado, 

 but judging from their known habits it is probable that a few 

 breed locally over much of the country from the mountains to 

 Kansas. In north central Colorado, at the western edge of the 

 plains, a scattered pair or two can be found breeding in most of 

 the sloughs or marshes. West of the range, Henshaw found 

 them breeding in southern Colorado in June and Dr. Coues 

 notes them as very abundant breeding at small lakes in North 

 Park. They are among the later migrants of the ducks arriv- 

 ing in northern Colorado early in April, and by the middle of 

 June have full clutches of eggs. 



142. Spatula clypeata. Shoveller. 



Summer resident; common, locallv; in migration, abund- 

 ant. This duck inhabits the whole of North America and is
