Field Marks and
Identifying Characteristics:
Was leading a Great Salt Lake Audubon field trip, first thing in the morning 30 feet from our parking area, a group of 8-10 warblers started actively foraging in the southern-most line of vegetation lining the north side of Douglas Corrigan Way. This bird stood out. Actively calling and foraging, mostly out in the open. Very cooperative bird. We actually had a participant who was ten minutes late and we were able to stay on the warbler until she arrived and get her looks. Pale overall, greenish yellow wing bars, bold eye ring, tail cocked, distinctive upper side color. Minimal "chestnut" coloration on the flanks, making me think it is a HY Male.
(see photos)
Song or call & method of delivery: Calling constantly. Sounded like a loud version of a Yellow Warbler chip
Behavior: Actively feeding in Willows, Russian Olives and pines. Calling the whole time. Often cocking tail
