Human development threaten eco system

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

Page 8: Snowy Owl

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

Page 9: Snowy Owl

Longevity and Mortality Longevity is up to 10 years

If in captivity they can live up to 35 years

Page 10: Snowy Owl

Seasonal Patterns Nocturnal and Diurnal

The snowy owl hunts all winter Mink, weasels, fox, and hawks also

hunt all winter

Page 11: Snowy Owl

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 Humans, wolves, artic foxes,

jaegers, wild dogs, and other avian predators

Page 13: Snowy Owl

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 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
