This guy, with his daily dive-bombing and chasing from "his" feeder, was clearly giving me the "stink-eye." It was amazing that with hardly any remaining light at 6:44 p.m., sunset at 8:11 p.m.; completely clouded and him facing nearly opposite the low clouded-over sun (him facing SE), he could still produce iridescence like this.. just amazing. I'd always thought there was a certain directionality of the light, but not entirely diffuse like this. You can see that every direction of the head cover and gorget except downward is able to emit light. I learned something from him, about his talents. Shutter at 1/30 sec. !!
