3-5 lemming per day(1600 per year)
Also eat rodents, large hares, insects, fish, small songbirds, and geese
Have very strong stomach acid, so they eat the prey whole
Humans, wolves, artic foxes, jaegers, wild dogs, and other avian predators
Snowy owls has played a major role in many children books, mythology art, and movies
They are very territorial
Won’t kill you but can extremely injure you
They have very sharp talons that can cut your scalp or even blind you
Not a lot of humans live in the Artic so we are not very affected by them
No pigment in their feathers
The lack of pigment in their feathers allows more space for air that helps the Snowy Owl to keep the bird warmer because air is an insulation against cold weather.
Feathers with fringes that help muffle sound when they fly
Binocular vision just like humans
Bony eye sockets
3 eyelids—one for blinking, one for sleeping, and one for keeping the eye clean
In different directions on their head
The sound of predators reaches their ears at different times, so they can tell the distance of the animal
