Saunders on the birds of Montana. 



[A distributional list of the birds of Montana, with notes on the 

 migration and nesting of the better known species. By Aretas A. 

 Saunders. Pacific Coast Avifauna of the Cooper Ornithological Club, 

 no. 14, pp. 1-194 ; map and 35 hgs. from photos. Berlieley, California, 

 1921.] 



The State of Montana is nearly three times the size of 

 England ; it lies along the northern boundary of the United 

 States, and its western third is traversed by the Rocky 

 Mountains, which, however, do not rise above an elevation 

 of 11.000 feet, while its eastern two-thirds consists of 

 plateau land forming the prairies. Settlement of jMontana 

 came rather late, but much development has taken place 

 during the last ten years and has brought about many 

 changes in the bird-life. The Trumpeter-Swan, the Sand- 

 hill and Whooping Cranes, the Sage-Hen and Long-billed 

 Curlew, formerly common, are now becoming rare owing to 

 closer settlement, and Mr. Saunders has done well to place 

 his observations and those of his predecessors on record. 



A short introduction is followed by a chapter on dis- 

 tributional areas in Montana, illustrated by a sketch-map. 

 The list of species with their status and selected breeding 

 and migration records occupy the greater part of the volume, 

 and after this comes the introduced species and hypothetical 

 list. The number of species recorded is 333. The work 

 appears to have been very carefully done and will doubtless 

 form a standard list of the birds of the State for some time. 

 The text is enlivened by a number of photographs of nests, 

 eggs, and birds by various contributors excellently well 

 reproduced.
