Blue-headed Vireo - Mountain Road, Gill, Franklin Co., MA. October 2nd, 2013.
The prize, however, or perhaps another near miss, was a Connecticut Warbler which began calling spontaneously as I walked on the track under the powerlines. It stayed low in dense undergrowth offering just one, all-too-brief, dorsal view but showed uniform olive upperparts, brownish head and a conspicuous white eye-ring. I was able to track the bird through the undergrowth by following its calls but never got another look, never mind an image. It seemed to slip away with a Ruby-crowned Kinglet and that was that. Despite the migration window for this species coming to an end in Massachusetts, I'll keep plugging away as I'm still optimistic about photographing a Connecticut Warbler before the season for them is over.
