Dendroica pinus pinus (Wilson)
Northern Pine Warbler

Uncommon migrant; summer resident south to Mason and Huron counties.

First listed for Michigan by Sager (1839: 414): "Vermivora pinus."

SPRING.-The northward migration occurs chiefly during the fourth week of April and the first half of May.

Lower Peninsula.-L. W. Campbell (1940: 195) has observed these warblers in the Toledo-Erie marsh area from the middle of April to the middle of May (April 17, 1938; May 17, 2023). In the Detroit area J. Claire Wood (1908e; 480) collected 1 (U.M.M.Z) on April 19, 1908, and Swales saw 1 at Grosse lie on April 23, 1909. A specimen (U.M.M.Z) was collected April 28, 1939, by R. L. Patterson in the Ann Arbor region, and the species is usually reported there in late April or early May, though occasionally seen in June; R. E. Olsen recorded 1 on June 10, 1934. D. W. Douglass collected 1 (U.M.M.Z.) April 18, 1933, and saw 2, April 30, 1933, on Sand Point, Huron County; R. L. Patterson saw 2 near Gaylord, Otsego County, on May 7, 1939; and William Brewster and Jonathan Dwight secured several specimens (M.C.Z.) near Oden, Emmet County, between May 10 and 24, 1888.

Upper Peninsula.-There is 1 definite spring record: S. S. Gregory, Jr. (1929 :186), listed the species in the Huron Mountains, Marquette County, on May 8.

SUMMER.-The Pine Warbler is fairly abundant locally; the young leave the nest in July.

Lower Peninsula.-N. A. Wood and Gaige (1911; 301) listed this species as the most abundant breeding warbler on Sand Point, Huron County; they noted many fledglings, and, on June 16, found 1 nest under construction. Chaney (1910: 277) mentioned a nest with 4 eggs found in western Mason County on July 12. Leonard Wing (1933: 73) found the species "abundant" in Crawford County; he collected several fledglings (U.M.M.Z.) on July 4 and several more (U.M.M.Z.) July 31 and August 1. Gibbs found it well distributed near Cadillac, Wexford County (Barrows, 1912: 624) ; at Douglas Lake, Cheboygan County, Blanchard and Nelson (MS of 1937) noted adults feeding young in late July (1919 and 1923).

Upper Peninsula.-Brodkorb occasionally observed Pine Warblers at Seney, Schoolcraft County, from June 2 to June 11, 1938; northward, in the vicinity of Whitefish Point, Chippewa County, N. A. Wood (1914:71) found the species common in the pine forests. S. S. Gregory, Jr. (1929: 186), listed it as an uncommon summer resident in the Huron Mountains, Marquette County, and 0. McCreary observed an adult feeding young in the Porcupine Mountains, Ontonagon County, on July 19 (N. A. Wood, 1905:178).

FALL.-Available information indicates that the fall migration occurs from mid-August to late September in the Upper Peninsula and to mid- October in the south.

Upper Peninsula.-On Isle Royale a Pine Warbler was seen by Walter E. Hastings on August 5, 1929, and several by Fargo between August 18 and September 6, 1924. Considerable numbers were noted at Deer Park, Luce County, by B. E. Olsen and A. D. Tinker: 10 on August 30, 20 on September 1, and 20 on September 2, 1938. Fargo saw Pine "Warblers at Whitefish Point, Chippewa County, in 1925; he found them the most numerous in September, but recorded "many" on several occasions between August 18 and September 7. Christofferson at Blaney, Schoolcraft County, noted 10 on August 5, 1936, and 8 on September 8, 1932; Bryens at McMillan, Luce County, recorded 1 on September 29,1935.

Lower Peninsula.-N. A. Wood and Gaige (1911: 301) observed the Pine "Warbler on Sand Point, Huron County, until August 3, after which none were seen until August 18, when small flocks were common on the point. Gibbs (1885a; Vol. 25, p. 304) noted the species in "some numbers" in Lake County from October 12 to 15, 1883. A Pine Warbler was seen near Ann Arbor by A. D. Tinker as late as October 25 (1938), and it has been reported by L. W. Campbell (1940: 195) from the Toledo-Erie marsh area between September 5 (1939) and October 22 (1938).
