The predominantly diurnal Snowy Owl is perfectly adapted to its habitat. Their plumage effectively protects them against the cold, from their beak to their toes. To camouflage better when breeding, the females feathers are much thicker than that of the smaller male.
The rearing success of the Snowy Owls depends directly on the quantity of their main food source, lemmings. During good "lemming years" more owls breed. Each individual pair can raise up to twelve offspring.
