Snowy Owls are diurnal, which means that unlike most other owls they are active and hunt during the day and night.
The diet of Snowy Owls consists mainly oflemmings. They are known to sit and wait for their prey and spend most of their time perched still and silent on prominent lookouts.
Lemming populations are cyclic and in years when lemming populations are down Snowy Owls often leave the arctic regions and fly south in search of food. Because of this, about onceevery four yearsSnowy Owls are found as far south as the northern and central United States.
An adult Snowy Owl can eat three to five lemmings per day, or up to1,600 per year.
The feathers of Snowy Owls haveno pigment, leaving more space for air which helps them to keep warmer because air is such a good insulator.
