STATE AGRICULTURAL COLLEGE BULLETINS. 



149 333-(49o). Accipiter oooperi (Bonap.). * Cooper's Hawk; Chicken Hawk. 



Very common; throughout the state; May to October; E. L. Moseley shot one at 

 Grand Rapids, March 27, 1886; '•common at Port Sanilac, where it is said to breed, 

 though I have never taken a nest'' (W. A. Oldtield); "common migrant at Macki- 

 nac Island" (S. E. White); "Kevieenaw Point" (Kneeland); breeds; nests in May in 

 trees; "took set of five eggs at Plymouth, April 24, 1892" (J. B. Purdy); "breeds 

 commonly in Kent Co." (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); "the common Hen Hawk and an enemy 

 at St. Joseph and Albion" (O. B. Warren); eggs two to six, undistinguishable 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 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. 



15^-334 (4J)(>). 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.; "rare at Albion" (O. B. Warren); "young male 

 taken at Heisterman's Island, Saginaw Bay, August 6, 1888" (N. A. Eddy); taken 

 by A. H. Boies in Hillsdale Co., and by S. E. White in Kent Co., and seen by him 

 at 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).
