The Birds of Colorado. 



Colymbus auritus. Horned Grebe. — Two near Barr, May 5, 1906 

 (Hersey and Rockwell). 



Larus californicus. California Gull.— One seen in 1905 at Coventry 

 (Warren). 



Larus franklini. Franklin's Gull. — One October 17, 1907, at Barr 

 (Hersey and Rockwell).

Sterna forsteri. Forster's Tern. — Twelve pairs were found breeding 

 at Barr, May 19, 1900 (Felger). 



Sterna hirundo. Common Tern. — The second supplement prophecied 

 that this species would sometime be added to the list of Colorado birds, 

 since it is a regular visitant to Kansas and Nebraska and has been taken at 

 Cheyenne, Wyo. This prophecy is now fulfilled by the capture of a speci- 

 men, May 14, 1908, at New Windsor by G. E. Osterhout. The bird was 

 sent to the Biological Survey for identification. 



Phalacrocorax vigua mexicanus. Mexican Cormorant. — The first 

 record for Colorado is a specimen taken October 15, 1899, at Smith's Lake 

 near Denver (Felger). 



Mergus serrator. Red-breasted Merganser. — A mounted specimen 

 was seen at La Veta (Gary), and the catalogue of the National Museum 

 records a specimen taken at Fort Massachusetts [= Fort Garland]. These 

 are the second and third records west of the front range. 



Marila americana. Redhead. — This species can now be added to the 

 list of the breeding birds of Colorado as it is known to have nested at Barr 

 Lake, Adams County (Hersey and Rockwell). 



Marila vallisneria. Canvas-back. — This also joins the breeding birds, 

 since eggs were found July 4, 1900, at Barr Lake (Felger).
