Iberian Magpie (Cyanopica cooki)
Common Tern (Sterna hirundo)
Build like a Magpie, but slightly more slender. Black hood, white throat, buff body and beautiful azure-blue wings and tail. Unmistakable if seen well. In unfavorable conditions the long tail in combination with the black hood and contrasting pale throat is diagnostic. Sexes alike. Flight similar to Magpie, but less staccato and more decisive. Behaves more like a Jay than a Magpie, and usually moves about in small groups.
Sound:Most typical call is a high-pitched, finch-like, rapidly ascending "hvrriit" (similar to some Siberian Jay or Jay calls). Has a rich repertoire various social sounds of which some are more Magpie-like, like a dry and rolling "krrrrrrr".

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.
