Captive light photo day

This is my third Captive light photo day now and I've enjoyed all of them. This one was the flying day. So hard to capture the birds in flight but very rewarding when you get a shot right. The whole day was spent waving my 150-500 Sigma lens around as the birds fly majesticaly around. They are not daft as they swoop down from out of the sun, Really good day. Next one is Owls in the forest,
