I’ve watched several Forster’s Terns the last few times I’ve been to the rice field impoundment. They are incredibly acrobatic in flight, twisting and turning, then swooping down to the water to go after small fish.
They are quite striking birds, even in non-breeding plumage. When they’ve make the turn and loop back for another run at the pond is the best opportunity to photograph them.
And did I mention they are fast? This is the best I got this day for a dive.
If they pick up a small fish with their feet they quickly pass it to their mouth and down the hatch it goes.
