These tiny birds are very fidgety, zipping from twig to twig in search of a morsel. And usually with their backs to me. I probably took 200 frames, and only a few captured the golden crown and something approaching a decent head angle (I know, another degree or two wouldn't hurt). From Cape May last Wednesday.

Yes, I agree a better head angle would have been excellent, but I understand what it is trying to get good images of this species! I've had a bit of luck using audio with them, but not a whole lot. Good details and clinging pose. I also like the few berries.
