Appearance:

Similar to Common Whitethroat but, with greyish fringes on secondaries and shorter tail and wings. Forehead less steep than in Common WT. Upperparts evenly dark brown with no contrast between shoulders and back. Head grey with slightly darker ear-coverts. Throat and belly white. Legs dark. Tail dark with white edges.

Sound:

Song typically consists of two parts. An indistinct chattering and warbling, subsong-like part similar to Whitethroat, which is usually followed by a dry, fast and rattling trill. The trill carries much further than the chattering part. May be difficult to identify if trill is omitted. Warning call a hard "check" similar to Blackcap but slightly softer

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.
