Well worth it, Eric. I've shot a lot of egrets, great blues, ibises, snowy egrets on the wing. They're all white, except the great blue, and he's fairly light. You can grab them in the finder and focus. The limpkin is camouflaged, and grabbing him against the background trees ain't easy. Here's a failure from yesterday. I've got a lot of failures, but today makes up for them.
