And here's the pics separately. Forster's tern catching a squid at Moss Landing, CA.

Was at Moss Landing for a project on sea otters. More on that later. I also took tons of pics of terns and I kept just missing them catching food. Or so I thought. I got back this afternoon and discovered this series. I never knew this was in their diet. #Birds

Saw TONS of raptors at Yolo Bypass this weekend. Will post a bunch of pics later. But wanted to share pics of this one American Kestrel. It was definitely putting on a show. It even seemed to want to announce something. #birds
