that a Downy Woodpecker taken at Holly in extreme eastern Colorado is 

 homorus, the same as the bird of the mountains.] 



Dryobates scalaris bairdi. Texas Woodpecker. — A long extension of 

 the known range to the eastward results from the finding of this species in 

 Baca County; four were taken April 17, 1905, and one May 12, 1905, near 

 Springfield (Warren). Several at Swink, October 29, 1908 (Smith). 



Centurus carolinus. Red-bellied Woodpecker. — Seen at Yuma, 

 October 1, 2 and 3, 1906 (Patten). 



Colaptes auratus luteus. Northern Flicker. — One, October 5, 1906, 

 at Yuma (Patten). One, October 24, 1904, Hall Valley, Park County, at 

 10,000 feet (Felger). 



Lieut. J. W. Abert states in his report that when he visited Colorado in 

 1846, he found the Flicker with yellow wings common all along the Arkansas 

 River in Kansas and that they continued to be common westward in 

 Colorado at least to the mouth of the Purgatory River. Abert ascended 

 the Arkansas to the site of the present town of La Junta, and then went 

 southwestward to Raton Pass. It was not until he was half way between 

 La Junta and Trinidad that he saw the Red-shafted Flicker, and here 

 both the yellow and the red forms were common. A great change has 

 taken place in the distribution of these two forms during the sixty years 

 that have elapsed since Abert's Colorado visit. Now the yellow-winged 

 form is extinct in the whole Arkansas Valley of Colorado and the red- 

 shafted form has extended its range eastward throughout this whole region 

 and far into Kansas. 



Antrostomus vociferus. Whippoorwill. — The first record for Colorado 

 is that of one taken September 14, 1903, at Fort Collins and sent to the 

 Biological Survey for identification (Burnett). 



Cypseloides niger borealis. Black Swift. — A female in the collection of 

 Geo. B. Sennett is labeled as taken at Denver, June 26, 1884. This is the 

 most northeastern record for the State. 



Aeronautes melanoleucus. White-throated Swift. — Found at 

 Pawnee Buttes in northeastern Weld County (Henderson). Common 

 breeder in Chimney Canon near Sterling (Cary). 



Selasphorus platycercus. Broad-tailed Hummingbird. — Humming- 

 birds have been seen at Springfield May 24, 1908 (Alexander) and at 

 Yuma May 31, 1905, September 5, 1908, and October 3, 1908 (Patten). 

 In each case the records probably belong to the above species, and these 

 seem to be the first records of hummingbirds from the plains of eastern 

 Colorado. 



Selasphorus rufus. Rufous Hummingbird. — One, August 27, 1904, 

 near Antonito (Bailey). 



Stellula calliope. Calliope Hummingbird. — The two previous records 

 of this species for Colorado are each of single birds; it is surprising there- 

 fore that several should have been seen in one day August 27, 1904, at 

 Antonito, by Vernon Bailey of the Biological Survey.
