104 Wll.D AXIMALS OF GLACIER NATIONAL I'AKK. 



examined in the files of the Bnreau of Biolo<>ical Survey, and lists 

 of birds observed during short visits to the park have been kindly 

 turned over to me by Mr. Harold C. Bryant, of California, and Mr. 

 P'dward E. Warren, of Colorado. To these gentlemen, as to Mr. 

 E. S. Bryant, taxidermist, of Columbia Falls; Mr. Walter Scott 

 Gibb, assistant chief ranger of the park; Mr. William C. Gird, park 

 guide; Mr. Harry P. Stanford, taxidermist, of Kalispell; and Mr. 

 Donald H. Stevenson, formerly a park guide, I Avould extend my 

 sincere thanks for much valuable information. Records of a hundred 

 and eighty-seven species have been obtained altogether, but nuiny 

 more doubtless remain to be discovered by future workers in the park. 

 The illustrations are from photographs by Messrs. Vernon Bailey, 

 A. C. Bent, E. J. Cameron, J. E. Haynes. H. W. Nash, H. & E. 

 Pittman, Robert B. Rockwell, J. Rowley, Hon. George Shiras, 3d, 

 and Mr. E. R. Warren; and drawings by Maj. Allan Brooks and 

 by Messrs. Louis Agassiz Fuertes, Bruce Horsfall, John L. Ridgway, 

 Robert Ridgway, and Ernest Thompson Seton; and in the main 

 have appeared previously in the publications of the Bureau of Bio- 

 logical Survey, U. S. Department of Agriculture, and the National 

 Association of Audubon Societies ; in Bird-Lore ; and the Handbook 

 of Birds of the Western States, published by the Houghton Mifflin 

 Company. 



The classification and nomenclature used in the report are those of 

 the 1910 Check List of the American Ornithologists' Union, the Six- 

 teenth Supplement, and the proposed changes in The Auk, up to 

 April, 1918. 



II. WHERE THE SUMMER BIRDS MAY BE FOUND. 



The park with its heavy forest cover and its snow banks and glaciers 

 would seem an unlikely place for birds to spend the summer, as few 

 species care for either deep forests or snow-clad mountains; l)ut 

 while general conditions limit the abundance of birds found within 

 the boundaries of the park, certain local conditions increase their 

 numbers, so that by knowing where to look one may find a richly 

 varied bird population. AYhile birds breed within fairly definite 

 boundaries governed by temperature during the breeding season, 

 many of thi>m wander widely afterwards, and in the late summer 

 may be encountered almost anywhere in the park. 



BIRDS OF THE LOWEIi LEVELS. 



Around the warm outer margins of the park — in the Lake INIc- 



Dontild and the North Fork of the Flathead regions on the west, 



and the St. IVIary, Sherburne I^ake. and Belly River regions on the 



. east — islands and tongues of Transition Zone prairie together Avith 



swampy meadows, sloughs, and large lakes affording more or less
