Silberkehl-Schwanzmeise Aegithalos glaucogularis

An energetic little bird with a tennis ball body and a long tail. Dark above and pale below with a dark gray patch on throat. Usually found in small flocks of its own species, foraging noisily and acrobatically in temperate forests and parks. In the far northern part of its range, overlaps marginally with Northern Long-tailed Tit, which lacks the gray throat patch.
