Pinicola enucleator leucura (Muller) Canadian Pine Grosbeak (A.O.U. 1998: Pine Grosbeak)

Pinicola enucleator eschatosus Oberholser*
Eastern Pine Grosbeak (A.O.U. 1998: Pine Grosbeak)

Winter visitants, regular but uncommon in the north; irregular and rare south of Ingham County. The Eastern Pine Grosbeak possibly breeds on Isle Royale and in the Porcupine Mountains, Ontonagon County.

Pine Grosbeaks were first recorded for Michigan by Kneeland (1857:236) .

Van Tyne's findings (1934: 529-30), based on 58 specimens, indicate that the Eastern Pine Grosbeak is the more common of the two forms in winter. Since the two occur together and are indistinguishable in the field, the records for both forms are here grouped in a single account.

FALL.-At McMillan, Luce County, Bryens (1939: 103; and notes) records the arrival of the Pine Grosbeak every fall, nearly always during the last week of October or during early November. Walter C. Wood (1905: 50) noted "many large flocks" on Les Cheneaux Islands, Mackinac County, between October 15 and November 15, 1903. An Eastern Pine Grosbeak (U.M.M.Z.) was collected on November 23, 1941, at Butterfield, Missaukee County, by N. S. Potter, III; and another (Max M. Peet collection) on November 1, 1933, near Harrison, Clare County, by Max M. Peet. Pine Grosbeaks were recorded on and after November 19, 1883, in Bay County (Eddy, 1884: 41); on November 25, 1903, at Vicksburg, Kalama- zoo County (F. W. Rapp, 1931: 21) ; and on November 25, 1921, at Waterloo, Jackson County (Walter Koelz, 1923: 38). Two Eastern Pine Grosbeaks (U.M.M.Z.) were collected at Ann Arbor on November 7, 2023 (N. A. Wood, 1903a: 96-97), and 2 (examined by Swales) at Detroit on November 9, 2023 (Eppinger, 1903a: 96; Swales, 1904: 43; 1904a; 83).

WINTER.-Pine Grosbeaks have varied considerably in numbers in Michigan and in the extent of their flights (Gibbs, 1893d: 39-41; 1896: 94). The species was fairly common during the winters of 1903-4, 1906-7, 1929- 30, and 1933-34.

Upper Peninsula.-S. S. Gregory, Jr. (1929: 181), found them "rather rare'' in the Huron Mountain region, Marquette County; Van Winkle (1892: 186) termed them "not rare in winter, but not abundant" in Delta County, and George H. Shiras, 3d (1935:108), considered them not common in Alger County. At McMillan, Luce County (Bryens and Fritz, 1930: 45; Bryens, 1939: 103; and notes; Leonard Wing, 1940: 195;U.M.M.Z.), they occur every winter, and a flock of 42 was recorded there in late December in 1929. Christofferson has recorded the species in small numbers fairly regularly at Blaney, Schoolcraft County, and elsewhere in the eastern part of the peninsula.

Lower Peninsula.-According to Barrows (1912: 466-68), Pine Grosbeaks have occurred almost every winter, sometimes in flocks of 150 to 200, as far south as Lansing; Gibbs (1885: 86; 1893d; 39-41; 1900: 140) re. ported them at Kalamazoo only two winters (1873-74 and 1874-75) ; in the second winter he noted "large flocks ... at nearly all times in our public park." The species occurred in the Ann Arbor region in the winters of 1903-4, when specimens (U.M.M.Z.) were collected, and a flock of 20 reported (N. A. Wood, 1903a; 97) ; of 1906-7, when 2 individuals were seen (N. A. Wood, 1921a; 592) ; of 1921-22, when 4 were taken by Walter Koelz (1923: 38) on November 5; of 1929-30, when specimens (U.M.M.Z.) were collected, and a flock of 8 seen, on January 31 (A. D. Tinker) ; and of 1933-34, when specimens (U.M.M.Z.) were taken (R. E. Olsen, 1932: 480- 81; 1935: 100).

SPRING.-The species has usually left the southern counties by late February or early March, and the Upper Peninsula by late March or early April.

Lower Peninsula.-A Canadian Pine Grosbeak (U.M.M.Z.) was collected, and 2 other Pine Grosbeaks seen, near Detroit, on March 14, 1930, by Tyrrell (19316: 126). A specimen (U.M.M.Z.) was also collected on March 14 (1896) at Locke, Ingham County, by T. L. Hankinson. The species was recorded at Vicksburg, Kalamazoo County, on March 8, 2023 (F. W. Rapp, 1931: 21); at Greenville, Montcalm County, from March 21 ("many") to March 24 ("some") in 1897 (Selous, 1897: 25) ; and in Bay County until March 10 (1884-Eddy, 1884: 41). Several specimens . (U.M.M.Z.) of both subspecies were collected in Butman Township, Gladwin County, March 9 and 10, 1934, by J. C. Salyer.

Upper Peninsula.-At McMillan, Luce County, Bryens (1939: 103; and notes) has found Pine Grosbeaks usually until late March or early April, and in 1930 until April 30. At Palmer, central Marquette County, 0. B. Warren collected a Canadian Pine Grosbeak (Michigan State College; identified by Van Tyne) on March 18, 1894.

SUMMER.-Specimens of full-winged immatures (U.M.M.Z.) difficult of subspecific determination (Van Tyne, 1934: 529-30) were taken in mid- August: 1 on Isle Royale (Max M. Peet, 1909: 364), and 1 near Ontonagon (Walter Koelz, 1923: 38; N. A. Wood, 1923: 338). Bryens (1939: 103) saw an individual at McMillan, Luce County, on August 29, 1927.
