Karl Overman: Birds and more

 
 

Historically speaking, Worm-eating Warbler is a relatively recent addition to Michigan’s  avifauna with the first record coming from the Cranbrook Campus in Oakland County on May 20, 1961.  Alice Kelley, Birds of Southeastern Michigan and Southwestern Ontario 68 (1978).  Once it crossed that important threshold, it has become an annual bird in Michigan presumably as overshoots in spring migration.  When it has been suspected of breeding in the state, it has been in western counties such as Allegan and Berrien.  Perhaps that pattern is changing.  The Oakland County bird below is on territory and two have been reported from this locale near Holly.  Also on the east side of the state, a bird was on territory in the Lapeer State Game Area, even further north than this bird, in late May and early June of 2011.
