I think the red legs and black bill would have to make it a non-breeding Arctic Tern.

Another hard one. Not a White Fronted Tern because of the red legs, and not a Common Tern because the tail is extending beyond the wings. Don't think its an Antarctic Tern either because the bill is all black, leading to the conclusion that its a non-breeding Arctic Tern. Forehead looks right, and little carpal white patch also typical, small and pale.

I suck at terns. How about testing us with a photo of a fantail next time?

My first thought was that it couldn't be a white-fronted tern because that's too ubiquitous -- surely it must be a common or Arctic? -- but the more I looked at it the more I kept coming back to white-fronted.

Although the legs look very reddish and the forehead steep, I figure it can't be an Arctic tern because the bill looks too big and long, but more importantly (as I understand it) the cap in non-breeding Arctics is behind the eye not above it as here.

Conversely the forehead looks too steep for the common tern, and the bill looks straighter rather than with the curved upper edge as I have seen in photos of commons.

So, even with the reddish legs etc, I'm going to go with the white-fronted tern (Sterna striata) as my answer
through the course of evolution lemurs became monkeys, monkeys became apes, apes became man, and man became a jerk.
