298 Warren, Birds of the Elk Mountain Region, Colo. [j,J|y 



Hillside Lake, October 28, 1899. When on Muddy Creek, in July, 1901, 

 Adams and Hooker spoke of seeing a " Wood Duck " with a brood of young 

 swimming in the creek. From the description they gave of the bird it 

 appeared to be this species. They called it Wood Duck because it nested 

 in trees. 



Anas platyrhynchos. Mallard. — Fairly common in migi-ation about 

 Crested Butte. Seen as late as October 14, 1905. In 1901 and 1902 the 

 species seemed common on the numerous little ponds found in the high 

 ground between Muddy Creek and Ragged Mountain, and were no doubt 

 breeding there. November 2, 1901, three were seen on Muddy Creek, 

 not far below the Botsford Ranch. 



Nettion carolinense. Green-winged Teal. — Not uncommon in 

 migration about Crested Butte. Carl Bergman told me that a teal of 

 some species raised a brood of young at the Hillside Lake in 1914, but he 

 could not say if it was the present or the following species. 



Querquedula discors. Blue-winged Teal. — Probably not uncom- 

 mon in migration. I have one record for Marble, a freshly killed bird 

 which I found dead in Yule Creek, October 4, 1902. 



Spatula clypeata. Spoonbill. Shoveller.— Has been taken at 

 Hillside Lake. 



Marila americana. Redhead. — I saw three which were killed on 

 Hillside Lake, October 18, 1902. 



Erismatura jamaicensis. Ruddy Duck. — One was killed on Hillside 

 Lake, May 31, 1899. 



Botaurus lentiginosus. Bittern. — I saw one which had been killed 

 at Green Lake, above Crested Butte, October 22, 1900. 



Nycticorax nycticorax naevius. Black-crowned Night Heron. — 

 One was killed near Crested Butte some time in May, 1915. I saw the 

 mounted specimen. No one there had ever seen such a bird. 



Grus mexicana. Sandhill Crane. — • In 1901, '02 and '03 there were 

 a few Cranes about the little ponds near Muddy Creek, already mentioned 

 in speaking of the Mallard. June 5, 1903, C. F. Frey and myself found a 

 nest with two eggs. A full description of this was published in the Condor, 

 VI, No. 2, March, 1904, p. 39. The nest was on one of several tussocks of 

 grass which lay more or less in a line on a mudbank or island, and made of 

 swamp grass, irregular in shape, and about two feet across, a mere platform. 

 On this lay the two large eggs, looking, as Frey said, Hke turkey eggs. 

 While I was taking pictures of the nest on the seventh the parent birds, 

 and the female (I suppose) especially, kept flying about, uttering their 

 outlandish notes. 



Porzana Carolina. Sora. — One seen at Hillside Lake, September 23, 

 1900. 



Fulica americana. Coot. — Common migi-ant about Crested Butte. 

 I saw a " Mudhen " on Hillside Lake, June 20, 1915, and the people at the 

 ranch had noticed it a few daj'S previously. 



Catoptrophorus semipalmatus inornatus. Western Willet. —
