Another photo from my extensive file.

This Snowy looks like he/she's going to hammer in the fence post!

One curiosity: The bird's white colour has a warm tint, while the background snow seems a cooler white!

Canon ESO 5D Mark III with the superb 500 F4 lens, handheld @ 1/1000, f/9, ISO 400 with +0.7 exposure compensation. Cropped for composition. Photoshop auto contrast filer applied. Selective sharpening of claws and some head feathers.
