All snowy owls have black spots on them when they are younger, but when they start to age more they show if they are a male of female. Females have more black spots and males kind of loose spots over time. An adult snowy owl can up to eat 7-11 mice a day but can go 40 days WITHOUT FOOD! Snowy owls have lots of feathers to stay warm when they are in the tundra. The largest owl species ever found weighed 6 pounds and had the wingspan of 5 feet! Their diet consists of mice, fish and sometimes other birds. Their diet is carnivore. They live up to 10 years in the wild and 48 years in captivity . My favorite thing I’ve learned about snowy owls is that they can go so long without food.
