l'>7-lib2 (o^ii). Haliivetus leiicocoplialiis (Linn.). *Bald Eagle. 



Not rare especially in the uninhabited regions of the north; "rare in Monroe Co.. 

 but a pair have their nest on the Raisin River near its mouth" (Jerome Trombley); 

 all months of the year; two in our museum killed in January, one from Ingham 

 and the other from Shiawassee Co.; found common at Bay City by N. A. Eddy (O. 

 and O. Vol. IX, p. 4); '"one old pair has nested for past twelve or fifteen years in 

 same patch of woods, seven miles north of Port Sanilac. If tree with nest falls 

 they build in another" (O. W. Oldfield); "Grand Traverse Co." (Dr. M. L. Leach); 

 N. A. Eddy is satified that it breeds on the islands of Saginaw Bay; "common 

 in- the Upper Peninsula" (S. E. White); "rare now, but said to be quite common 

 at St. Joseph previous to 1870, though now common at Palmer, Marquette Co. where 

 it breeds and is frequently taken in traps" (O. B. Warren); "quite common in the 

 Gogebic region of the Northern Peninsula" (H. Nehrling); breeds; "a pair of young 

 taken from nest at Byron in spring of 1892" (J. B. Purdy); "breeds in Cheneaux 

 Island, Mackinaw Straits" (Dr. M. Gibbs); "breeds on Keweenaw Point" (Kneeland); 

 nests in tall trees, "using the same nest year after year" ^. J. Davis); eggs two, 

 rarely three, nearly spherical, dirty white. The late Prof. W. K. Kedzie secured two 

 of the young here in 1868. which he reared to maturity; "I have caught them alive 

 in steel traps mounted on top of poles" (S. E. White). We have only these two 

 eagles in the United States. The young differ so widely from the adult that many 

 suppose that we have several species. 



Subfamily FALCONIN.^. Falcons. 



Genus FALGO Linn. 



158-354a-(498). Falco rusticolus gyrfalco (Linn.). *Gyrpalon ; Jerfalcon. 



"Said to have been taken ' in the state in winter" (Gibbs' Birds of Michigan); 

 "probably on Keweenaw Point" (Kneeland); "south to the United States in winter" 

 (Jordan). Dr. Gibbs writes me that he should retain this, as his authority was the 

 late Dr. G. B. Wilson. 



159-356-(503). Falco peregTiuus anatiim (Bonap.). *Duck Hawk; Peregrine 

 Falcon. 



Rare; taken by Dr. Atkins at Locke, Nov. 2, 1881; throughout the state; "rare at 

 Ann Arbor" (Dr. J. B. Steere); "one specimen taken in Monroe Co. in 1886" 

 (Jerome Trombley); "two Michigan specimens in the collection of the Kent Scientific 

 Institute at Grand Rapids" (E. L. Moseley); Davie says it has been known to breed 

 in Michigan; rather common northward, and doubtless found in spring, summer and 

 fall but not in winter; "breeds at Michigamme" (Davie, p. 187); "breeds on southern 

 shore of Lake Superior" (Prof. Ludwig Kumlein). This species is given in Sager's 

 list of 1839. 



160-357-(50o). Falco coliimbarius Linn. *Pigeon Hawk. 



Rare; throughout the state; "occasional at Ann Arbor" (Dr. J. B. Steere); all 

 seasons, or at least a summer resident'; "taken at Grand Rapids" (E. L. Moseley); 

 ■'Monroe Co., rare" (Jerome Trombley); "Mackinac Island" (S.E.White); "Kewee- 

 naw Point" (Kneeland); taken by Mr. A. H. Boies in Hillsdale Co., where he has
