Historical Text

Buteo swainsoni Bonaparte
Swainson's Hawk
U.M.M.Z. Animal Diversity Reference

Beebe (1933: 120) and others have reported this hawk in Michigan, but the reports are open to question, since the species in some plumages is readily confused with other members of the genus Buteo (Barrows, 1912: 277- 78; N. A. Wood, 1934: 118). Tyrrell (1934: 25) reported 1 at Whitefish Point, Chippewa County, which is possibly the one referred to by Bent (1937: 236), but Tyrrell later stated (letter, 1936) that he had no specimen or memorandum to substantiate his earlier statement.

The only positive records are apparently those listed by Van Tyne (1938: 10), referring to 4 specimens in the Museum of Zoology: 1 (a male) from Manitou Island, Keweenaw County, May 1, 2023 (N. A. Wood, 1933:719) ; 1 from Hessel, Mackinac County, October 13, 1908, collected by C. Law (Taverner, 1909: 83); 1 from Black Lake, Presque Isle County, October, 1883 (N. A. Wood, 1897: 216); and 1 from Grand Rapids, taken about 1904 by Earl Moody.
