Empidonax virescens (Vieillot)
Acadian Flycatcher

Summer resident north to Saginaw County.

First listed for Michigan by Sager (1839: 413): "Tyrannula acadica."

Since the Acadian Flycatcher is not easily distinguished from the Alder and Least Flycatchers, both more common in Michigan than the Acadian, this account of its distribution in Michigan is based chiefly on specimens. There is no verified specimen from north of Saginaw County, though various workers have listed sight records from the north: N. A. Wood, Smith, and Gates (1916: 13) and Compton (1914: 178) in Cheboygan County; S. E. White (1893: 225) on Mackinac Island; and Max M. Peet (1909a; 105) on Isle Royale. (White reported that he collected "many specimens" on Mackinac Island, but these were not examined by a qualified ornithologist.)

SPRING.-The species migrates into the southern half of the Lower Peninsula during the last half of May; Swales (1903: 36) noted its arrival about the middle of the month in the Wayne County area. Specimens (U.M.M.Z.) taken in southeastern Michigan include 1 by D. C. Worcester, May 15, 2023 (Ann Arbor), 1 by A. D. Tinker, May 14, 2023 (Hartland Township, Livingston County), and 1 by Walter Koelz, May 20, 2023 (Waterloo, Jackson County). N. A. Wood (1922: 18) saw the species daily in Berrien County from May 10 to June 1, and secured several specimens (U.M.M.Z.) there; B. F. Sykes took 1 (U.M.M.Z.) at Kalamazoo, May 21, 1879. Swales collected 1 in Atlas Township, Genesee County, on May 30, 1905, and at the Prairie Farm, Alicia, Saginaw County, G. A. Ammann observed several between May 26 (when he collected a specimen) and June 14, 1940.

SUMMER.-Although Brownell (1887: 96-97) took what he believed were eggs of this species on May 10 (in Wayne County), this early date needs confirmation, since other available records indicate a much later nesting season (June and early July). Swales found 1 nest with 3 eggs as early as May 30 (1900), and a nest with 3 young on July 19 (1903). N. A. Wood (1922: 18) noted the species during July in Berrien County and took several specimens on July 7 and 18. Gibbs (1885:134), in Kalamazoo County, and Swales (1903: 36), in Wayne County, noted it as a common summer resident; Max M. Peet took an adult male near Ann Arbor on June 12, 2023 (Max M. Peet collection); R. E. Olsen found a nest under construction in Hartland Township, Livingston County, on June 2, 1935; Fargo saw a nest with eggs near Jackson on June 10, 1923; and G. A. Ammann saw the species several times during the second week of June (1940) at the Prairie Farm, Alicia, Saginaw County.

FALL.-The Acadian Flycatcher migrates southward in August and early September. Swales (1903: 36) noted its departure in the "latter part of August" in Wayne County, and Gibbs (1885: 134) reported that it was '' rarely seen after August 1" in Kalamazoo County, but in Berrien County, N. A. Wood (1922: 18) saw the species until September 10 (1917). Fall specimens (U.M.M.Z.) have been taken in Wayne County: 1 on August 18 (1906, by Swales), 1 on August 30 (1908, by Swales), and 1 on September 11 (1904, by Taverner). J. 0. Strong collected 1 (U.M.M.Z.) in Hartland Township, Livingston County, on September 10, 1931, and Van Tyne took 1 (U.M.M.Z.) near Tompkins, Jackson County, September 13, 1930. H. B. Sherman secured specimens (U.M.M.Z.) in Berrien County: 1 on August 31 and 2 on September 5, 1917.
