Warbler day here at Heron Pond. A Nashville Warbler (I think, which would be a lifer), an adorable little bird that my wife Lisa believes is an immature Black-Throated Green Warbler (based on the yellow head, streaked flanks and white chest) and lastly a bird with an eye ring, gray face and wing bars that has me totally stumped.

The consensus is that my mystery bird is an immature Chestnut-side Warbler. I agree now that its been pointed out to me. The other IDs were confirmed as well.

What a day...3 new life list birds seen at home.
