觀察細節
Photographed. Not the same individual listed here as Thayer's/Iceland. This bird had medium-dark eyes. Relatively large-billed for this species. I considered Herring x Glaucous-winged because the bill seemed large, but settled on Thayer's (probably male given the bill size) due to the whitish underside of the far P10, the greenish bill base, the relatively large white tongue-tips on P7-P8, and the lack of any black smudging on the bill. Thayer's is also more likely here than Herring x Glaucous-winged.
