Terns - Northern sea (1 Viewer)

[Nikolai Kolev]

I have some blury pictures of terns for identifiction, which i made before few days(7-8.05.2023). The pictures a made from the ship between Cuxhaven and Helgoland island(Germany). I am wondering, if all of them a common terns, or arctic/roseate with which i don't have experience. Also on the last picture, are they whiskered terns? I received a comment on observation.org, that this species is rare in the area.

Hello Nikolai,
do you have more pictures?

001: is a Common Tern, I think a single picture is enough for confident ID.
002:: there is at least one Common Tern. I am not so sure about the left bird: it might be a Common Tern, the third bird from left might be an Arctic Tern by extravagant long tailed jizz and shape, the right bird might be an Arctic too (??? More pictures please)
003: difficult bird for me. This seems one example imo, where motion blurre might well shift shape towards Arctic, with a slender, full breasted body and exagerrating the long tail. But if more pictures confirm, that the secondaries are darkish, then its a Common Tern imo.
004 Common Tern: ??? More pictures please!
005: More pictures, please! I see birds that look good for Black and Whiskered Tern.
