the less active fowls " (Dr. A. K. Fisher); ssen soaring high up in the air; " less common 

 than the next species at Mori-ice " (Dr. W. C. Brownell); founi at all months, " but not 

 common in winter, indeed much less so than the next species" (E. L. Moseley); breeds; 

 Mr. K. R. Willhelm has taken over 150 eggs in Kalamazoo Co. in four years; nests in 

 March and April, in high trees; nest very largs; eggs two to four, white, often soiled, 

 nearly always spotted with reddish brown. This is the common Hen Hawk of the 

 farmers. 



149-339(520). Biiteo liueatns (Gmel). *Red-shouldered Hawk; Red- 

 shouldered Buzzard; Hen Hawk. 

 Very abundant; throughout the state; March to Sept.; occasional in winter; 

 "Mackinac Island" (S. E. White); general and nesting habits and eggs much as in the 

 preceding species except the eggs are a trifle smaller an:l more coarssly specked; B. 

 Swales has taken a set of five eggs; K. R Willhelm has robbed over ninety nests in 

 Kalamazoo Co. Dr. A. K. Fisher states that both of these species are our friends; 

 Prof. Ludwig Kumlein writes me that this and the last species rarely take poultry, if 

 they ever do. 



150-3J:2-(523). Buteo swaiusoni Bonap.. Swainson's Hawk. 



Exceedingly rare; one killed by A. H. Boies in Hillsdale Co ; one killed in Genesee 

 Co., where it was identified by Dr. M. Miles (Miles' Birds of Michigan, p. 231); Mr. 

 Jerome Trombley writes me that he has taken the nest and eggs in Monroe Co.; "the 

 food of this bird is largely composed of lo3usts" (L. S. Foster). 



1.51-343-(52-t). Buteo latissimus (Wils.). Broad-winged Hawk. 



Common; summer resident; " common at Ann Arbor " (Dr. J. B. Steere); "Hillsdale 

 and Lenawee counties" (A. H. Boies); "a retired bird, found only in deap woods" (Dr. 

 M. Gibbs); E. E. Brewster thinks this species rather common at Iron Mountain; 

 "Mackinac Island" (S. E. White); breeds; Dr. Gibb3 took the eggs near Kalamazoo, 

 May 27, 1875; nests and eggs taken by Jerome Trombley at Petersburg, inMonroa Co., 

 where it is not uncommon; S. E. White writes that he took nest and four eggs in Kent 

 Co., June 25. 1891; Dr. A. K. Fisher writes that it destroys myriads of locusts. These 

 hawks sometimes occur in flocks of several hundred during autumnal migrations" 

 (Prof. Ludwig Kumlein). 



Genus ARUHtBUTEO Bbehh. 



152-347a-(525). Archibnteo lag-opus sancti-jokaiinis(Crmel.). *American Rough- 

 legged Hawk. 



Rare; Sept. to May; Dr. Atkins reports finding a nest in Locke, May 18, 1876, which 

 was doubtless an error; " they do not breed in the United States " (D;. A. K. Fisher); 

 "one specimen taken at Plymouth in fall of 1892" (J. B. Purdy); "ons taken by Mr. 

 .Dempel, of Hillsdale, April 7, 1892" (F. M. Falconer); "Mackinac Island and Kent Co." 

 (S.E.White); "Keweenaw Point " (Kneeland); "Iron Mountain Oct. 23. 1892" (E. E. 

 Brewster); "rare and only in winter in Mjnroe Co." (Jerome Trombley); Prof. Ludwig 

 Kumlein, of Milton College, Wisconsin, writes m3 that he has taken one nest in Dane 

 Co., Wisconsin, and one other nest in that state with two young in it, but he thinks 

 this species not a regular breeder in the limits of the United States. This species is 

 embraced in Dr. A. Sager's list of 1839. 'Feeds almost entirely on small rodents" (Dr. 

 A. K. Fisher).
