There was a wonderful assortment of birds this morning on Black Butte Ranch. WILSON'S SNIPE, WILSON'S PHALAROPE, WILSON'S WARBLER, YELLOW WARBLER, WILLOW FLYCATCHER and another EMPIDONAX sp. were among the most cooperative.
FEMALE YELLOW WARBLER:
The two flycatchers were about 1/2 mile apart. Unfortunately, neither bird vocalized. Both bobbed their tails up first, then down helping me rule out Gray. I noted off-white wing bars, olive-gray upperparts, white to yellow-tinged underparts, and a faint eye-ring on the first bird. The second bird's posture was more erect than the first and it was darker overall, with whiter wing bars and had a longer primary-projection. I've tentatively identified the first bird as a WILLOW FLYCATCHER, and the second as a DUSKY FLYCATCHER.
