Appearance:

Glossy black hood and plain, pale brown upperparts. Cheeks brownish towards nape. Small, rounded, black bib. Small pale spot on base of upper mandible (often surprisingly visible, despite small size). Very similar to Willow Tit, especially British sub.sp. Willow tit has bigger head, not so glossy cap, whiter cheeks, larger bib and pale wing panel.

Sound:

Most easily identified by sound. Especially in areas where plumage is less distinct compared to Willow Tit, like in Britain. Most typical call an explosive, sneeze-like "pee-choo", starting high-pitched and ending on a lower note.

Also calls "chaa chaa chaa" but not so nasal and drawn-out as willow tit. Song: A simple one or two note call repeated in series. Usually rising slightly in pitch, and with a "liquid" quality. Sometimes also a ringing, vibrating song. Generally has a much sharper tone than the soft song of willow tit. Other calls: Various high pitched sound. Often quite explosive.
