Before taking off to hunt at twilight, this owl sits on a tree looking for mice and listening carefully to hear if a rodent gives itself away with any sound.
The snow hides the owl's main prey — mice — who remain under the layer of snow as it is much warmer and offers a protection against predators. Their dark fur is clearly noticeable on the white background.
Hearing the squeak and fuss of a mouse in the snow, the owl dives headfirst into the snow towards a mouse, catching it.
