Icterine Warbler (Hippolais icterina)
Common Tern (Sterna hirundo)
Green upperparts and yellow underparts. Sides of bill yellowish, legs slate grey. Short yellow supercilium which connects to yellow lore. Long wings and relatively short tail. The flat crown and long bill gives it a different head profile from Sylvia warblers. Often raises crown feathers. Very similar to Melodious Warbler, but differs from this in pale wing-panel and longer wings. Folded wings reaches tip of under tail coverts, and primary projection is as long as tertials. Juveniles paler than adults, with whitish supercilium. The pale wing-panel extends to fringes of greater coverts in addition to secondaries. Alert and agile bird. Usually hidden in foliage, also when singing.
Sound:Contact call distinct. A hard, trisyllabic "che-che-fink" , or "che-che-weet" with upward inflection. Song very virtuous and varied. Most similar to Marsh Warbler, but timbre and attack harder and more powerful. Tempo varied with many pauses, but includes longer, and more flowing sequences than Marsh Warbler. Song frequently interrupted by characteristic, nasal, high-pitched squeaks unlike Marsh Warbler. Master of mimicry. Imitations are often repeated several times before changing to melodious motifs or more "noisy" phrases.

CCDiffers 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.
