An unusual siting in Western Nebraska, I do not think his coloring is helping him blend in. Snowy owls are another owl species that primarily hunts during day.
Some times it is better to be lucky than good. Upon spotting this owl, we hurried to get pictures before it flew away. It wasn't until after getting home and looking at the photos did we notice the horse shoe underneath.
The sky was very overcast, with large grey sky and light yellow background, it made exposing tricky, but I think we pulled it off.
