Vireo philadelphicus (Cassin)
Philadelphia Vireo

Uncommon transient.

First authoritatively listed for "Michigan by Gibbs (1879 : 485).

SPRING.-The Philadelphia Vireo passes northward through Michigan in the latter part of May.

Lower Peninsula.-L. W. Campbell (1940: 134, 193) found the species a rare migrant during mid-May in the Toledo-Erie marsh area, and Swales (1904: 38) listed it as a rare and irregular migrant in the Detroit area. There is a specimen in the Max M. Peet collection taken by Peet near Ann Arbor on May 11, 1918; 2 others (U.M.M.Z.) were taken in the same locality in May: 1 by Walter Koelz on May 17, 1918; 1 by L. D. Case on May 12, 1937. The Philadelphia Vireo was inadvertently omitted from the re- port on the Berrien County expeditions (N. A. Wood, 1922) ; the species was found to be the most numerous of the vireos in the county from May 20 to 27, 1918, and 5 specimens (U.M.M.Z.) were secured. Gibbs (1885: 68) re- cords a specimen taken at Kalamazoo May 23, 1882; Barrows (1912: 569) mentioned 2 collected at East Lansing, Ingham County, on May 9, 1897; and D. W. Douglass secured 1 (U.M.M.Z.) at Sand Point, Huron County, on May 22, 1932.

Upper Peninsula.-Christofferson has recorded this vireo after the second week in May in the vicinity of Blaney, Schoolcraft County (2 on May 16, 1937; 6 on May 20, 1938; 6 on May 22, 2023). N. A. Wood (1914;70) collected 1 (U.M.M.Z.) on Whitefish Point, Chippewa County, May 27, 1914, and A. Murie secured 1 (U.M.M.Z.) on Isle Royale June 11, 1930.

FALL.-Fall migrants are reported from the last week of August to the end of the third week in September.

Upper Peninsula.-One Philadelphia Vireo was seen on Isle Royale September 1, and 2 on September 12 (Peet, 1909: 372), and 2 (U.M.M.Z.) were collected there by N. A. Wood on September 17, 1929. Ira N. Gabrielson secured 1 in the Huron Mountains, Marquette County, on September 21, 1936. Christofferson records the main flight through Blaney, Schoolcraft County, during late August and early September (August 31, 1937, 5 seen; September 4, 1933, 12 seen), noting the first arrivals in early August (August 2, 1937, 1 seen).

Lower Peninsula.-Max M. Peet secured a specimen (Max M. Peet collection) September 15, 1940, at Burt Lake, Cheboygan County, and "Walter Koelz collected 1 (U.M.M.Z.) August 29, 1919, near Alpena. Two specimens (U.M.M.Z.) were taken by George M. Button near Pinckney, Livings- ton County, 1 on September 7, and 1 on September 14,1940. J. Claire "Wood (1909 : 46) collected several (U.M.M.Z.) in September, 1905 (1 each day on September 3, 10, and 24) in Wayne County, and Taverner secured 1 (U.M.M.Z.) in the same county on September 27, 1908. There is 1 October record for Jackson County: a specimen (U.M.M.Z.) taken by L. D. Case at Portage Lake, October 1, 1939.
