On 20 July 1970, Stephen E. Ross, then a student at UMBS, picked up a fledgling vireo dead in a road that traversed a beech-maple woods back from the Lake Superior shoreline, about one mile west of the parking area for Grand Sable Falls in Alger County. The young bird must not have been out of its nest for more than a day or so since its tail was still very short. In "A Distributional Check-list of the Birds of Michigan" by Dale A. Zimmerman and Josselyn Van Tyne (Occ. Papers of the Museum of Zoology, U. of Michigan, 1959), the Philadelphia Vireo is listed as an uncommon transient in Michigan, with one reported nesting in Crawford County, but "no positive mid-summer records ...from any part of the State." Stephen Ross's find thus appears to be the first positive evidence that the species breeds in Michigan.
