A beautiful snowy owl looks like she is flying above a cloud, but in fact she is gliding inches above a snowplain in a hunt for food. The owls fit in perfectly with their surroundings as both the male and female, which has darker markings on her feathers referred to as barres, hunt for voles.

Nature photographer Rick Dobson captured the two birds hunting in corn fields near his home, just outside of Ottawa, Ontario, Canada. (Photo by Rick Dobson/Solent News/SIPA Press)
