I'm wondering if we can discount this bird as a possible 1st year Arctic
Tern.
The left wing is in a really bad way with a big chunk of primaries missing
in the middle.
I strongly suspect that the two fresh primaries that appear to show narrow
dark tips are primaries 3 and 4, if that was the case it is problematic for
Common which typically doesn't show dark tips until around primary 5. Note
also how transluscent the wing is, and how the dark tips don't feed onto the
leading vein of the feathers. Admittedly the wing is rather compromised
however but I thought that Arctic may be worth considering.
Have you got any more images of this bird Roger, no matter about image
quality.
Cheers Jeff.

Can anyone assist me in identifying this Tern I photographed at Stockton
Breakwater, Newcastle? I was not birding at the time and had no binocs, just
the camera. I just got around to looking at the photos from the day.
