At one point last night there were 100+ Common Tern ant-catching with the Med Gulls over the Denes. It's been years since I've seen terns do that! Several groups also flew south over land.

I was pretty sure I had a couple of Black Terns go past here with a group of common, last night, but they were a bit too far out. Just had a much closer one, lingering with a group of feeding Common Tern.
