Vindicated!

According to eBird, other people have since spotted my mystery bird at Presqu'ile and come to the same conclusion I did, so I think it's safe to say that I did indeed find a Prothonotary Warbler. Well outside of what is considered its usual range, as far as I know. But as a friend recently reminded me: it's migration, weird crap happens.

The obligatory bad photos:











A warbler with a bright yellow head and breast, grey wings, white undertail coverts, and no other visible markings (e.g., eye ring, wing bars, streaking). It probably should have been a no-brainer from those clues, but hey, when you find an Endangered species in a place where it really shouldn't be, you can't help but second (and third, and fourth) guess yourself.
