(Description:) Field Marks and Identifying Characteristics:	While following a brightly colored Cassin's Vireo in the trees near the hummingbird feeders, I noticed a large warbler foraging nearby. Initially I got a glimpse of two bright white wingbars which immediately grabbed my attention. I followed the bird and saw the long crisp white undertail coverts making the tail look short and thick, faint streaking on a drab yellow breast and immediately realized it was a Blackpoll Warbler. Cameron Cox and Allison Anholt were nearby and I called them over to confirm the sighting, as they both have extensive experience with eastern warblers. Cameron noted the pinkish legs and slightly lighter yellow/orange feet. We followed the bird around the picnic area for a good 15 minutes or so and got a few ID photos. We birded around the Ranch for about 45 minutes and were about to leave when the Blackpoll popped out in the sun in the same tree that we initially spotted it. Cameron got an excellent photo, and we watched it forage for another minute or so. Other notes: faint broken eye-ring with a dark eye-line and long wings. (see photos)
Song or call & method of delivery:	Did not notice chip or flight call during sighting, but easily could have missed it with all the warbler commotion at the ranch.
Behavior:	Foraging/gleaning insects 10-25 ft. up in planted trees, mostly the elms in the picnic area at the ranch.
Habitat:	Elm canopy at the ranch.
Similar species and how were they eliminated:	Non-breeding Bay-breasted are a brighter yellow, usually with some yellow near the vent and have less streaking with black legs and feet. Adult Pine Warblers are a brighter yellow, show little to no streaking with black legs and feet. Immature PIWA would be gray or a more dull yellow overall.
Previous experience with this & similar species:	I have extensive experience with eastern/boreal warbler species although it has been a few years since I have seen them. I saw two Blackpoll Warblers in Utah last fall - one at the exact same location only two days later, and one at Bountiful Pond.
