Skua - Dutch coast (IJmuiden) - Sept 29, 2023 (1 Viewer)

[Frank-birding]

Last Friday I saw this Skua chasing a (Herring?) Gull, very far out at sea. I wonder if it's an Artic or Pomarine Skua. It's size (as large as chased gull) and perhaps (in some images) broad wings and square tail remind me of the latter. The former being much commoner here however. The rounded wingtips in the first few images amaze me in any case by the way, this I have never seen before (can a skua's wing display rounded wingtips at all, of is it some sort of artefact?)
I'm afraid the images are too small to tell, but I do hope I'm too pessimistic?

I doubt this is identifiable with certainty but the extensive white flash and apparent double white in 298 suggest pom

Thank you for helping me with this ID. Too distant to be certain indeed, as is often the matter with the seabirds I see unfortunately... And good tips for future IDs of pomarine vs artic. Regards, Frank
