Do Snowy Owls Hunt During the Day or Night?

Chance encounter, of the majestic Snowy Owl kind-

I wasn’t expecting to see a Snowy Owl overhead in a pine tree, although its not entirely uncommon. Because Snowy Owlets hatch in the summertime in the treeless Arctic tundra, they may never even see a tree until they migrate southward.

Generally, Snowies prefer wide open spaces such as dunes, sandy beaches, fields, and airports, because this habitat looks most similar to the tundra.

For the same reason (their home territory is above the Arctic Circle), Snowy Owls hunt during the day in their summer range. Their eyes have evolved to hunt in the continuous daylight of the far north. When migrating to the lower 48 states, Snowies adapt to the shifting light. Unlike other species of owls, the Snowy Owl hunts during the day (this behavior is called diurnal), the night (nocturnal), and at twilight (crepuscular).

From observing Snowy Owls in our region, they mostly feed very early in the morning, before daybreak, rest during the day in dunes and fields, then at day’s end, fly up and perch on an open rooftop or phone pole (less occasionally to treetops), to begin hunting again. The elevated perches provide better visibility for triangulating prey.

Beach structures make great perches.

Even a flag pole makes for a terrific hunting perch for a Snowy!

A change of pace from thoughts of blizzards and nor’easters. Today while organizing photos for my upcoming lecture programs, I came across this funny random photo never posted. Read more about Nathan Wilson’s Great Auk sculpture and the extinct bird that inspired the installation at the Paint Factory this past summer here.
