What a work of art it is! This was photographed 5 days after the image I posted previously, and she was already sitting on four eggs. I have not had the chance to go back, and it is past the length of time it takes to incubate and have the young fledge for this species, so I will never know the ending of the story. Very low light, despite being 10:15AM here - note the removed TC and raised ISO, plus the camera and lens were braced on top of my car's roof with some beach towels underneath (I was lucky I could photograph this nest from the road), plus liveview used with 2-second timer...so...NOT handheld!
Canon 7DII + 500mm f/4 II, manual exposure, evaluative metering, 1/100s., f/4, ISO 3200, natural light, FF, a couple of distracting highlights removed or toned down from the BG, NR to the BG and tail.
