Possible Eastern Common Tern

A text from John Tymon alerted me to the presence of a black billed tern at
Pennington Flash today. It was a grim morning, pouring with rain from about
9am until noon and very dull. I was hoping for a roseate but John's message
didn't suggest that species and when I arrived at the hide the bird was
sitting on the spit and just looked like a common tern with a black bill.
Except that there were differences. The bill looked a bit too fine, black with
perhaps a hint of crimson at the base, the legs were long and black or very
dark red and it's underparts were greyish contrasting with very white cheeks.
This last feature was even more obvious when it flew, at which time its common
tern like primary pattern could be seen. The bird was so dark and it flew in
such marsh tern like way that for a moment we even considered and then
dismissed whiskered tern.

However it was obvious that it wasn't a marsh tern, but what was it?
