Action in the water

We are having some more very stormy weather this week and more is predicted, even a possibility of more flooding!! I hope not!!
I tooks some shots of a very stormy sea but as I had to go into Maclean this afternoon I took the camera and thought this made a change from the beach. It is looking up river towards one of the islands. the birds were going crazy, I think they were small Petrels, dozens of them flashing about and diving into the water to get what looked to be small prawns. There are a lot of types of Petrels but by zooming in on some of the birds I think they are White Necked Petrels, not very clear shots though. Edit - new info from Jen says it is a Gull-billed Tern. Gull-Billed Tern close up The Gulls were just floating about on the water casually picking up the odd prawn or whatever it was in the water.
