Appearance:

Unmistakable. Very small, mouselike bird with short rounded wings, short neck and upright tail. Upperparts chestnut brown and finely barred. Underparts light buff. Forages in thick undergrowth and low bushes, crevices and holes for insects. Easily overlooked, but betrays its presence by its big voice. One of the smallest bird in northern Europe.

Sound:

Song surprisingly loud. A high-pitched stream of clear notes resembling Robin and Dunnock in timbre. Differs from those in showing frequent shifts in pitch with much larger register than Dunnock, and by the unique, numerous, interspersed long trills. Warning call a short hard "teck", like banging two rocks together. Often repeated in series when excited to form machine-gun-like "firing".

Appearance:

Differs from Common Tern in shorter head, and blood-red bill. Legs shorter, but tail streamers longer (extends well past wings in sitting birds). Underparts of primaries with sharply bordered dark trailing edge (diffusely bordered in Common Tern). Both primaries and secondaries transparent to sunlight. Crest less apparent than in Common Tern and underside greyer. Cheeks white just below the black cap, often in contrast to grey lower cheeks. Juveniles lacks buff coloured back.

Sound:

Similar to Common Tern but higher pitched. Typical call a series of high pitched "tip-tip-tip", and longer, ringing, high-pitched "kriiiiii" calls. The drawn out "kree-aaahh" call falls less distinctly in pitch than Common Tern.
