432. Selasphorus platycercus (Swainson) — Broad-tailed Hummingbird. 



During the summer of 1891, Bruner saw on several occasions on 

 the Pine ridge in Sioux and Dawes counties a species of humming- 

 bird which he identified as this one, and a later intimate acquaintance 

 with it in Colorado confirmed his identification. The hummingbird 

 reported by J. M. Bates in Bruner's list from Cherry county (Valen- 

 tine) according to his own judgment also belongs here since he later 

 identified the Broad-tailed at Bassett, Sept. 10, 1899, thus establish- 

 ing its range half way across the state. (See Proc. N. 0. U., I, pp. 

 16-17.) In the adjacent states of Wyoming and Colorado this species 

 is common. 



EXTRALIMITAL: 433. S. rufus (Gmelin), the Rufous Humming- 

 bird, is a western species which is fairly common in Colorado and has 

 been taken at Cheyenne, Wyo., only about 6Q miles from the Nebraska 

 line.
