BIRDS 
NEWTON, ALFRED, AND GApDOow, Hans. A Dictionary of Birds. Adam & Charles 
Black, London. 1893-1896. 1058 pages. 
As the title indicates, the subjects such as “Feathers,” “Flight,” “Finches,” “Swal- 
lows,” etc., are arranged alphabetically, not systematically. Contains general information, 
not descriptions of species. Authoritative and very useful. 
Evans, A. H. The Cambridge Natural History. Vol. IX, Birds. The Macmillan 
Co. 1899. 
A general treatise on structure and habits of the various groups, more particularly 
for advanced students. Does not describe species. 
BrEEBE, C. WittiAM. The Bird: Its Form and Function. Henry Holt & Co. 1906. 
496 pages. $3.50. 
One of the most important recent books for general students of birds, containing much 
not found elsewhere in so accessible a form, concerning structure and adaptation thereof 
to habits. Not a descriptive work on anatomy, but rather on the relation of parts, with 
inquiry as to reasons therefor, taking up in order the feet, wings, bills, etc. Very useful 
for anyone fond of nature, and helpful in understanding like features in other groups, 
such as mammals, reptiles, etc. 
KEYSER, LEANDER S. Birds of the Rockies. A.C. McClurg & Co. 1902. 345 pages. 
$1.50. 
The title seems a misnomer. It does not describe birds or their habits to any great 
extent, but tells of the author’s interesting experiences in Colorado in search of birds. Its 
chief ornithological value is a briefly annotated list of Colorado birds in the back of the 
book.
