Hi Bill

The head and wings look right for non-breeding Gull-billed Tern, but I'm not sure about the tail. Or I wasn't until I found this image, which looks a lot like yours:

It's from a blog by Jan Axel:

So Gull-billed Tern gets my vote.

Hi folks, Bill here

I've just got back from Darwin (including a terrific morning's birding followed by lunch with Denise Goodfellow), topping a three week drive from Melboring.

There are a number of things that are bugging me, top of the list being a bird I spotted at great distance on Darwin Harbour - that is, feeding near the sewerage outfall south west of Government House (hmm, I wonder if there's any connection there...?)

I've got two photos, one reasonable, one not so great, links below. So far, candidates are Gull-billed Tern (non-breeding), White-winged Black Tern (non-breeding) and even a Red-tailed Tropicbird. Unfortunately, at such a distance I wasn't able to get a good idea as to how large the bird is, but I'd say it's not huge, but probably larger than a small Tern. The feet seem to be red, although it's been suggested that this may actually be chromatic aberration in the lens.

Suggestions?
