Nashville Warbler
Vermivora ruficapilla
This is an uncertain identification. Tveten has
no similar bird pictured or described.
Alsop (418) writes that "the only North American
warbler with a yellow throat, no wing bars, a white eye ring,
and a blue-gray head" is the Nashville Warbler. This bird
appears to have all four of those marks.
Lockwood & Freeman (169) write of the Nashville
Warbler, "Uncommon to abundant migrant throughout most of
the state, generally more common in fall than in spring."
So the geography does not exclude it being a Nashville Warbler.
