191 1. Burns, Frank L,. A Monograph of the Broad- 

 winged Hawk (Buteo platypterus) . By Frank L,. Burns, with the 

 co-operation of over one hundred American ornithologists, and the 

 compilation of the world's literature. Wilson Bulletin, Volume 

 XXIII, Nos. 3 and 4. 



The September and December numbers, covering pages 143 to 

 320, of the Wilson Bulletin, are devoted entirely to the presentation 

 of Mr Burns' exhaustive study of the Broad-winged Hawk. 



We find diagnosis of genus, species and subspecies, description 

 and synonymy of species and subspecies, vernacular names, geo- 

 graphical and local distribution, flight, food, voice, enemies, disposi- 

 tion in presence of other birds, disposition in presence of men, 

 disposition in captivity, migration, station, mating, nidification, 

 incubation, young, moult and renewal, and bibliography. Mr. 

 Burns has given much credit to authors consulted and to his own 

 correspondents. We may perhaps wish that he had generalized 

 more from the large mass of data examined. The bibliography 

 occupies nearly thirty-seven pages, and the author mentions that it 

 contains more than seven hundred titles. Fourteen half-tone figures 

 also accompany the paper. 



That Mr. Burns' work is exhaustive can hardly be doubted.

Mr. Beebe here discusses the history, name, distribution, gen- 

 eral appearance, parasites, field notes in Venezuela and British 

 Guiana, food, nests and eggs, enemies, photographing Hoatzins, 

 and odor, and concludes with a bibliography of forty-eight titles. 

 Seven half-tone plates illustrate the paper. It also contains a map 

 showing the known distribution of the bird.
