This bird was at Bosque del Apache National Wildlife Refuge one cold January morning and allowed a very close approach. So I was able to pick an angle with good light and a decent BG; the bird never moved. Ooops, I forgot to add shooting information: Canon 7DII, Canon 100-400 f/4.5-5.6L IS II at 400 mm; ISO 400, 1/4000, f/5.6.
