151-35J7-(51(»). IJiiteo horoalis {Gmel.). * Red-tailed Hawk; Red-tailed 

 Buzzard; Hen Hawk. 



Very common; throughout the state; "comuion at Port Sanilac where it nests 

 in April"' (W. A. Oldtiekl); "Iron Mountain" (E. E. Brewster); "rare summer 

 resident at Mackinac 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 valuable in destroying noxious rodents and insects and 

 when hard pressed, take a few of the less active fowls" (Dr. A. K. Fisher); 

 seen soaring high up in the air; "less common than the next species at Morrice" 

 (Dr. W. C. Brownell); found at all months, "but not common in winter, indeed 

 much less so than the next species" (P^. L. Moseley); "a very common friend at 

 Albion and St. Joseph, and not rare at Palmer, Marquette Co." (O. B. Warren); 

 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 large; eggs two to four, 

 white, often soiled, nearly always spotted with reddish brown. 



152-339 (520). IJiiteo lineatiis (Gmel.). * Red-shouldered Hawk; Red- 

 shouldered Buzzard; Hen Hawk. 



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

 "abundant at Albion and St. Joseph" (O. B. Warren); "common and breeds at 

 Port Sanilac" (W. A. Oldtield); "usually rare, but occasionally a common summer 

 resident at Mackinac Island" (S. E. White); "more common than the last species 

 at Bay City" (N. A. Eddy); general and nesting habits and eggs much as in the 

 preceding species except the eggs are a trifle smaller and more coarsely specked; 

 B. H. 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. 



153-342~(523). Bnteo svvaiusoiii (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); "I have never seen or heard of it in Monroe Co." (Jerome Trombley)^ 

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



15-l:-343-(524). Biiteo latissimus {Wils.}. Broad-winged Hawk. 



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

 dale and Lenawee Counties" (A. H. Boies); "a retired bird, found only in deep 

 woods" (Dr. M. Gibbs); E. E. Brewster thinks this species rather common at 

 Iron Mountain; "one seen at Mackinac Island September 1, 1889" (S. E. White); 

 breeds; Dr. Gibbs took the eggs near Kalamazoo, May 27, 1875; nests and eggs taken 

 by Jerome Trombley at Petersburg, in Monroe 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); "have taken two birds but no nest at Port Sanilac" (W. A. 

 Oldfield).
