64 Lincoln, Birds of the Clear Creek District, Colo. [j" n . 



Hydrochelidon n. surinamensis. Black Tern. — Rare. A single 

 bird of this species was seen over a small pond close to the Creek, August 

 19, 1910. 



Anas platyrhynchos. Mallard. — Not common. A few seen regu- 

 larly throughout the winters. 



Chaulelasmus streperus. Gadwall. — Not common. Feeds in the 

 water-cress ponds in small numbers during the winters. 



Nettion carolinense. Green-winged Teal. — Common at times 

 during the fall migration. Occasionally found in irrigation ditches or even 

 on the swiftly moving creek. 



Querquedula discors. Blue-winged Teal. — Although this little 

 duck nests commonly within twenty miles of Clear Creek, they are never 

 common here, a few pair usually making up the complement for the season. 



Spatula clypeata. Shoveller.— Mr. Rett noted a flock of about 30 

 individuals feeding in a field, flooded by an overflow, April 7, 1918. 



Charitonetta albeola. Bufflehead. — Accidental. On November 

 3, 1912, I saw three females and one male at the edge of one of the lakes 

 at Berkeley. This was within thirty feet of the rails of the electric road 

 but they paid but scant attention to the passing cars. This duck is rarely 

 more then common anywhere in Colorado. 



Botaurus lentiginosus. Bittern. — Rare. One secured from a 

 willow patch bordering one of the seepage streams, August 29, 1910. 



Ardea h. herodias. Great Blue Heron. — Summer resident; nests 

 near the Creek and the solitary figure of this bird is a regular feature of the 

 Clear Creek landscape. From two to four would be noted d lily. 



Nycticorax n. naevius. Black-crowned Night Heron. — Common 

 summer resident although I have never found their nests in this vicinity. 



Rallus virginianus. Virginia Rail.— Resident and fairly plentiful. 

 More specimens have been taken in the winter than summer months. 

 Adult and three downy young seen July 30, 1910. 



Porzana Carolina. Sora. — Rare. But two records are available; 

 one by myself on August 27, 1911, and another from the same section 

 taken May 29, 1912, in the Museum collections. 



Fulica americana. Coot. — A plentiful summer resident on the small 

 akes in the valley. 



Gallinago delicata. Wilson's Snipe. — Resident, but very erratic 

 in its time of greatest abundance. Generally, however, it is more numer- 

 ous in the fall or in mild winters. One secured March 26, 1913, from an 

 irrigation ditch not two feet wide running through a sandy country. 



Totanus melanoleucus. Greater Yellowlegs. — Rare. An occa- 

 sional example noted with flocks of T. flavipes. 



Totanus flavipes. Yellowlegs. — Fairly common during fall migra- 

 tions; rarely seen in the spring. 



Helodromas s. cinnamomeus. Western Solitary Sandpiper. — 

 On August 23, 1910, I secured one specimen of this bird from a flock of
