This little fella was feeding peacefully when it got momentarily spooked by something that I did not see. This prompted it to take a few quick strides with wings open before settling back to feed again.
Canon 7D + 500mm f/4 II + 1.4TC, manual exposure, evaluative metering, 1/1600s., f/5.6, ISO 800, natural light, handheld, cropped for comp, usual eye work. a couple of specks in the water cloned out.
You are quick to catch that wings-up pose as it happens so fast. With the muted light, I would sharpen the head and neck just a bit more. (Or maybe add contrast, I never can tell which will work best till I try a few things).
Sweet pose! Low angle perspective, as always from you, looks really good. Body is angled towards you in a pleasing way...I like how there is sharpness and a little motion blur in the subject (in all the right areas of course)....if that foot had only just cleared the surface of the water...! Can't have it all I guess :)
