Common Tern

Common Tern (eng.)
Fjordterne (da.)
Sterna hirundo (sc.)

I’m pretty sure of my indentification.
I’ve seen these Terns in Vejlerne, north of Jylland (Danmark), but the distance from me made me a little confused. They should be Arctic Terns, maybe.
The flying one is from Tibro, Örlen lake (sud Sweden).
