Lives mainly in open areas

Mountains

Meadows

conservation status
Conservation Status

International Union for Conservation of Nature (IUCN) Red List: Least Concerned

Population is decreasing however

When lemming supply is low, so is the number of owls

Human development threaten eco system

reproductive characteristics
Reproductive Characteristics

Breed in Alaska and northernmost part of Canada between May and September

At 2-3 years old the mature bird becomes able to reproduce

Lays 7-8 eggs, depending on food supply

Hatch after 32 to 34 days

Born 2-3 inches with dark feathers

25-26 days until they can leave the nest, the parents help feed for 5 to 7 weeks

They cannot fly well until 50 days of age

parental care
Parental Care

If hunting grounds are good, the parent owls may nest in the same spot for several years

Nest directly on the ground

The female incubates the eggs while the male will gather food and protect the nest

longevity and mortality
Longevity and Mortality

Longevity is up to 10 years

If in captivity they can live up to 35 years

seasonal patterns
Seasonal Patterns

Nocturnal and Diurnal

The snowy owl hunts all winter

Mink, weasels, fox, and hawks also hunt all winter

Diet

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

predator relationships
Predator Relationships

Humans, wolves, artic foxes, jaegers, wild dogs, and other avian predators

human relationships
Human Relationships

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

fun facts
Fun Facts

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

Eyes

Binocular vision just like humans

Bony eye sockets

3 eyelids—one for blinking, one for sleeping, and one for keeping the eye clean

Ears

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
