By the amount of black left in the crown and the upperwing pattern I'd go with Royal. ( but I could be wrong. )

Hi Chris,

Thanks for your input, however this species looks a bit small to be Royal and the beak is dark, not yellow/orange as on the Royal Tern.

IMO it is a 1cy Least Tern. It does have a tail, but it is just very short, which is a good feature of Least Tern. Compare with this first-summer bird:

It can possibly be a least tern, but not a first cy: there is way to much black on the cap. Compare to the one in this thread.

No, it is a 1cy Lest Tern. Note how the primaries (and primary coverts) become gradually whiter inwards, which is a certain sign of a 1cy tern. Older terns show a clear moult limit between worn and dark outer primaries and fresher inner primaries. The bird has a white crown, which can be seen if the photo is lightened.
