Sand Martins on the Patch

For nearly a week now we have had a Starling like mini roost of Sand Martins coming in at or just before dusk. Tonight it was about 8pm or just after. with a count of about 200.

The first pic. I had zoomed in so didn't get the full flock.

This is virtually the whole flock, try counting them.

By the time I took this shot it was almost dark, and because of the shutter speed I was using I had to lighten it up on the computer.
