Black-throated Bushtit (Aegithalos concinnus, 红头长尾山雀).
In Autumnal Changsha, in the forests and by the lakes and river, one can find mixed flocks of cinereous tits, yellow-bellied tits, Pallas's leaf warblers, and black-throated bushtits. The latter are easiest to find by the water, hunting insects and spiders.
