(Kneeland); breeds; nests in May in trees; " took set of five eggs at Plymouth, April 24, 

 1892 " (J. B. Purdy); "breeds commonly in Kent county" (S. E. White); F. M. Falconer 

 took two eggs from a nest in the spring of 1892, and later took five from the same nest; 

 "K. R. Willhelm of Kalamazoo climbed to nine nests from twenty to forty-five feet high 

 in one day and secured twenty -three eggs" (Dr. M. Gibbs); eggs two to six, undis- 

 tinguishable from those of the Marsh Hawk; free to visit poultry yards. I have known 

 one to dart down and carry off a chicken within a rod of where I stood; Dr. A. K. 

 Fisher, than whom there is hardly better authority, writes me: "The true Hen Hawk, 

 quite injurious, destroys pigeons and poultry, probably the only common harmful 

 hawk." Prof. A. W. Butler writes me to the same effect. It is sometimes known as 

 blue hawk, blue darter (South) and blue-tailed hawk. 



147-334-(496). Accipiter atricapillus {Wils.). American Goshawk. 



Occasionally seen in summer; more frequently in winter; more common north, 

 where it breeds; Dr. M. Gibbs writes me that it surely breeds in Wexford Co.; one in 

 our museum from Berrien Co.; taken by A. H. Boies in Hillsdale Co., and by S. E. 

 White in Kent Co., and Mackinac Island; one killed north by Elmer Durfee; Mr. Levi 

 Broas has a fine one in his collection taken by him in Ionia Co.; "this and the two 

 preceding species are the most harmful of the hawks, the others rarely prey upon 

 poultry" (Prof. J. A. Allen). 



Genus BUTEO Cuv. 



Red-tailed Hawk, natural size. 



148-337-(516). Buteo borealis (GmeL). *Red-tailed Hawk; Red-tailed Buz- 

 zard; Hen Hawk. 

 Very common; throughout the state; "Iron Mountain" (E. E. Brewster); "Macki- 

 nac Island" (S. E. White); "Keweenaw Point" (Kneeland); this and the next species 

 are among our most common hawks; "this species and the Red-shouldered are very valu- 

 able in destroying noxious rodents and insects, and when hard pressed, take a few of
