Hi all. Just see this bird over the Easter weekend, but having never seen one before I am not entirely sure what it is. A formal ID would be great :t:

I was wondering whether it is a Black Tern?

The last image looks like a Little Gull, and the Tern....with that underwing why not a White-winged Tern?

Cheers
 
....with that underwing why not a White-winged Tern?

Exactly because of that underwing. WWT have black underwing coverts that are highly contrasting with pale flight-feather bases. The OP bird shows a typical Black Tern underwing pattern.

Not a white-winged tern as that would have strong contrast between the pale flight feathers and the otherwise black underwing. This is uniform greyish = black tern.

Am totally aware of what a full adult WWT would look like regarding black underwing coverts, it’s the contrasting dark contrasting leading edge to the primaries that looked a bit odd, thus leading me to wonder if the bird’s black underwing coverts are yet to emerge, I don’t know the moult strategy of Marsh Terns?

That's an adult there, with an adult plumage. First summers (WWT and BT) stay in Africa, if that's what you mean re moult strategies...

EDIT: on the moult question: WWT go from white (winter plumage) straight to black underwing coverts (summer), with never going through grey, if that's what you were asking.

That’s useful to know.👍
