Appearance:

A small, tit-like passerine with brown back, grey head and diagnostic black mask. Plumage comparable to Red-backed Shrike, but build and behaviour very different. Male with broader mask than female. Juveniles with pale, uniform plumage, lacking mask altogether. May be confused with Bearded Reedling if mask not seen, but note shorter tail with no graduation. Tit-like behaviour, but less inquisitive.

Sound:

Call a sharp clear high pitched whistle "pju-eee-uu", with the middle part accented and with a raised pitch Or just an all descending whistle "pjuuuuuuu".
