觀察細節

Drab individual but showing complete white eye ring, gray head, yellow throat, yellow undertail coverts, whitish patch around legs, and olive upperparts without wing bars. Feeding, like so many of our lingering Nashvilles this season, in Siberian elms, visiting sapsucker wells and apparently gleaning minute arthropods from the still-green leaves of this Eurasian tree species. Very active and kinglet-like, also occasionally flicking its tail.
