280 Felger, Colorado Water Birds. [f$L 



132. Anas platyrhynchos. Mallard. — Resident. In summer, com- 

 mon; in migration, abundant; in winter common locally. A common 

 breeder along the Barr Lake Chain. A goodly number of this species 

 remain all winter about the lakes with some open water and along the 

 South Platte River. Common on Barr Lake and Upper Barr Lake in 

 winter. 



134a. Anas fulvigula maculosa. Mottled Duck. — Migrant; rare. 

 (March 15-?; Oct. 10-about Dec. 10.) Cooke refers to but three speci- 

 mens; one of which was taken by Wm. Osburn near Loveland, and the 

 other was reported by H. G. Smith as presumably coming from Colorado. 

 Aside from these, one was killed in the fall of 1895 by Vic. Kennicott at 

 Kennicott Club Lake, 3i miles east of Longmont, and I have one killed 

 just prior to Nov. 13, 1904, near Loveland. C. A. Kendrick says that they 

 are rare about the lakes on which he shoots near LaSalle, Weld County, but 

 that one is occasionally taken there. 



135. Chaulelasmus streperus. Gadwall. — Resident. In summer, 

 common; in winter, not uncommon; in migration, abundant. Common 

 breeder along the Barr Lake Chain. 



137. Mareca americana. Baldpate. — Resident. In summer, not 

 common; in winter, not uncommon; in migration, abundant. Only a 

 few pairs breed along the Barr Lake Chain. 



139. Nettion carolinensis. Green-winged Teal. — Resident. In sum- 

 mer, not uncommon; in winter, not uncommon; in migration, abundant. 

 Breeds along the Barr Lake Chain, but not in such large numbers as the 

 two following species. 



140. Querquedula discors. Blue-winged Teal. — Summer resident. 

 (April 5-Dec. 1.) In summer, common; in migration, abundant. Mr. 

 Durward Luper and Mr. L. B. Meek each shot a Blue-winged Teal on 

 Upper Barr Lake on Dec. 1, 1905. Occasionally a Blue-winged Teal is 

 found straggling along with a flock of Green-wings in its migratory flights, 

 sometimes as early as February and as late as December, but I know of 

 none that has remained during the winter. Have found by June 21 eggs 

 that were nearly ready to hatch and fresh eggs on June 26. 



141. Querquedula cyanoptera. Cinnamon Teal. — Summer resident. 

 (March 26-Nov. 1 to 15.) In summer, not uncommon locally, but not as 

 common as the former species; in migration, not uncommon locally. 

 While this species is regularly taken along the Barr Lake Chain, at some 

 of the other lakes in this area it seems to be rare. C. A. Kendrick stated 

 to me during the fall of 1908 that he had not seen one on the club lakes at 

 La Salle for four years. At that place between Nov. 1 and Nov. 15, 1903, 

 he shot two of this species during a hard snow storm and while standing 

 in one foot of snow. La Salle lies only 3 miles east of a north and south 

 line through Barr, so it seems strange that this species should not occur at 

 the former place more frequently, even though it is a western species 

 finding its extreme limit in eastern Colorado. Have found fresh eggs 

 June 13 and eggs advanced in incubation July 27.
