    Blue-gray Gnatcatcher / Polioptila caerulea

    : May and late Aug/early Sep, with from late Apr and to late Nov, in open deciduous woods, scrubby edges, and areas where migrants concentrate. There are several mid-summer records that are hard to characterize but it seems possible Blue-grays could breed here at some point.

    Miscellany: Blue-gray Gnatcatcher had been a bird of the southern swamps north to Delaware and S. New Jersey but beginning in the 1940s and 50s it expanded its range north and east. In the late 1970s it began breeding in southern Maine.
