The Birds of Monument Valley Park, Colorado Springs, Colorado. 

 By Edward R. Warren. Bird-lore for 1916.] 



Mr. Warreu is well kaowii for the excellent work he has 

 done iu extending our knowledge of the vertebrate fauna of 

 the State of Colorado, and the writer of this notice was 

 greatly indebted to hira for help when preparing his own 

 account of the birds of that State. In the first of these two 

 papers, Mr. Warren gives a list with ample field-notes of 

 the birds inhabiting part of Gunnison County, which lies 

 embedded in the main chain of the Rocky Mountains. 

 Most of tlie country to which these notes refer is situated 

 at an elevation of over 9000 feet, while many of the sur- 

 rounding peaks reach an elevation of over 14,000 feet. The 

 fauna tiierefore is essentially of a montane character, and 

 the lite-zones treated of are the Canadian, Hudsonian, and 

 Arctic-Alpine. Among interesting birds noticed at length 

 are the White-tailed Ptarmigan [Lagopus leucurus) and the 

 two Rosy Finches [Leucosticte tephrocotis and L. australis). 



In the second paper Mr. Warren gives a list of 103 species 

 of birds observed by hira in a beautiful park running along 

 the western boundary of the town of Colorado Springs, and 

 one of the many generous gifts to the town and State by the 

 late Gen. Wm. J. Palmer. Down its centre runs the Monu- 

 ment Creek, and as it is well planted with trees and bushes, 

 it forms a safe and convenient refuge for many species of 

 birds. The educational value of such places is very great, 

 and particularly in the United States, where the reckless 

 destruction of bird-life has gone on so long unchecked, 

 though now one is glad to see a very different spirit is 

 gradually spreading among the great masses of the popu- 

 lation.
