觀察細節

I thought this might a Willow Flycatcher, but since that species understandably got flagged (rarer as a spring migrant,), I will leave it as WWPE until I can get some opinions. A medium sized flycatcher with no eye ring, a yellowish belly and extensive yellow on the lower mandible. I thought the undertail coverts looked pretty clean cream/yellow, but maybe slight smudging upon review of photo. Weak wingbars. Unfortunately I never got a look at the primary projection. Photographed: The posture was fairly upright, maybe more like a WWPE.
