Appearance:

Very similar to Balearic Warbler but breeding range does not overlap. Also easily confused with sympatric Dartford Warbler due to similar build with long tail, high crown, short wings and spiky bill. Told from latter by all over lead-grey plumage, lacking vinous underparts. Female similar to male but lacks dark lore and throat is paler . Immature birds are very similar to immature Dartford Warbler and are best identified by call, but have less brown back, paler throat and dirtier and greyer underparts.

Sound:

Song hurried and similar to both Sardinian, Dartford and Spectacled Warbler, but is softer with more tinny timbre. Interwoven soft rolling "trrrrtrrr" usually become more prominent towards the end of each phrase which often is concluded by 3-4 clear whistling "wit". Alarm call a short, Stonechat-like and grating "treck", very different from both Balearic and Dartford Warbler.

Appearance:

Differs from Arctic Tern in longer head, and more orangy red, rather than deep red, bill. Tip of bill usually black. Legs longer, but tail streamers shorter than AT. Underparts of primaries with diffusely bordered dark trailing edge (sharply bordered in Arctic Tern). Upper side of primaries with dark wedge (less apparent in winter). Secondaries opaque. Crest more apparent than in Arctic Tern and underside whiter. Juveniles with buff back.

Sound:

Similar to Arctic Tern but deeper. Lacks latter's high pitched "tip-tip-tip" call, and the drawn out "kree-aaahh" call falls more distinctly in pitch.
