1893. — The Hawks and Owls of the United States 

 in their relation to Agriculture, by A. K. Fisher, 

 U.S. Department of Agriculture, Washington. One Volume, 

 containing 201 pages of text and 25 beautifully coloured plates. 

 This is a most interesting and useful work, showing that the 

 birds of prey are more useful to agriculture than otherwise. 

 X'o less than 2690 stomachs have been examined by Mr. 

 Fisher, and the contents are enumerated in the tables accom- 

 panying the species. Of these, 169 contained the remains 

 of poultry and game birds, 463 of other birds, 397 of 

 mammals, and 623 of insects. If the stomachs of the six 

 species which feed largely upon game and poultry are 

 eliminated, we have a total of 2212 stomachs. Of these 

 78, or 3 J per cent., contained the remains of poultry or 

 game; 257. or 11 percent., of other birds ; 945, or 41^ per 

 cent., of mice; 309, or 1 1 per cent., of other mammals; 

 and 599, or 27 per cent., of insects. 



With the help of this excellent book, the farmer will be 

 able to know which birds he may call his friends or his foes. 

 It is very desirable that similar publications should be made 

 in Europe and elsewhere, not only on the Birds of Prey, but 

 on all birds in general. I am certain that in doing so 

 many new facts will be discovered, and show that many of the 

 species of birds, which are considered now as injurious, will 

 turn out to be some of the best auxiliaries to Agriculture. 



During my expeditions in North, Central, and South 

 America, I have examined several thousands of stomachs of 

 birds, killed and skinned by me ; but unfortunately, I have 

 not made notes of their contents, excepting those of Humming- 

 birds, which always consisted of minute insects and honey.
