Sivarth on Arizona Birds. 



[A distributional list of the Birds of Arizona. By Harry S. Swarlh. 

 Cooper Ornithological Club. Pacific Coast Avifauna, number 10. 

 Pp. 1-133. Hollywood, Cal., 1914. 8vo.] 



For some years past the author of this Avork has been 

 engaged in field-work among the birds of the State of 

 Arizona, which we may remind our readers lies just to tbe 

 east of California aud to the north of the Mexican boundary- 

 line, in the south-western part of the United States. 

 Throughout the greater part of Arizona, which is nearly 

 equal in area to the whole of the British Isles, desert con- 

 ditions prevail, aud the rainfall is probably less than in any 

 State in the Union. 



Notwithstanding this the author has been enabled to 

 compile a list of 362 species and subspecies occurring within 

 the State. With each of these is given a brief outline of 

 the status or method of occurrence, as well as of the dis- 

 tribution withiu the State. An analysis of the avifauna and 

 a discussion of the life-zones, illustrated by a map, follows 

 the list, and the whole is completed by a careful bibliography, 

 the titles of which are arranged chronologically ; the first 

 one of these, by William Gambel, only dates from 18J3, 

 showing how comparatively recent the exploration of this 

 State has been. The work appears to have been very 

 accurately done, and will be of great service to all workers 

 in North American ornithology.
