SNOWY OWL HEDWIG WEEKLY UPDATE AND THE REASON WHY CROWS ATTACK OWLS

Our beautiful Snowy Owl Hedwig was last seen on Monday night, March 12th. This was also the night before the third nor’easter. She was perched on the railing of the Ocean House Inn facing towards the sea. The wind was blowing fiercely. Well after dark, and after making several attempts, she successfully flew in a southerly direction out over the water.

It has been two weeks since that last sighting and perhaps we will see her again, but I imagine her to be safe and undertaking her return journey to the Arctic tundra, well-fed from her stay on Cape Ann. Whether she was well-rested is another story. The great majority of people who came to see this most approachable of owls were respectful and considerate of her quiet space. The crows however, were nothing short of brutal. After learning about why crows attack owls, and the degree of aggression possible, I am surprised she lasted as long as she did, and without great injury.

Crows and owls are natural enemies because a murder of crows may mob an owl to death (or any raptor by which it feels threatened) and owls occasionally eat crows. Crows are diurnal, which means they feed during the day. The majority of North American owl species that they encounter are nocturnal (night feeding). In the case of Snowy Owls, which feed both day and night, their paths may occasionally cross, as happened when Hedwig moved into the crow’s territory along Gloucester’s Atlantic Road.

A flock of American Crows can run circles around most owls, pecking, dive bombing, chasing, and in some instances killing. Snowy Owls are the exception; they are larger, stronger, and faster flyers than other North American owl species. And too, Snowy Owls are closely related to Great Horned Owls, a species known to eat crows when they are roosting overnight. So even though a crow in our area may never before have encountered a Snowy Owl, they instinctively know danger is present.

With their incredible ability for recollection, crows are considered the brainiacs of the bird world. Daily, Hedwig outsmarted this smartest of bird species. She learned to stay well-hidden during the daylight hours, laying low atop the hotel roofs. Her salt and pepper coloring blended perfectly with the black, white, and gray colors of industrial roof venting equipment. She adapted to hunting strictly at night, after the crows had settled in for the evening, returning to her hideouts before the day began.

Where’s Hedwig?

From Hedwig’s perch atop the Atlantic Road hotels, she had a crystal clear view of the golf course and Bass Rocks, places prime for nightly hunting.

On one hand it would be fascinating if Hedwig had been outfitted with a tracking device. On the other, if she had been trapped for tagging, she may not return to this area. There is some evidence that Snowies occasionally return to an overwintering location. Next winter I’ll be taking more than a few peeks in the location of the Atlantis and Ocean House Inn Hotels to see if Hedwig has returned.

Snowy Owl Feathers in the Moonlight

Hedwig is the gift that keeps on giving! What a joy to see her awakening in the rising full moon last night. She preened and fluffed, then flew through the moonlight to a nearby phone pole.

The wind was whipping up and ruffling Hedwig’s feathers, making her look extra fine in the glow of the Snow Moon rising.

Dear Friends,

While I am sorting through the challenges of one of the hard drives for my Monarch film crashing, I have been organizing the Snowy footage. Captured in photos and on film, we have her bathing, passing a pellet, pooping, eating, flying, and much more, and is going to make a terrific short film. It’s a mystery to me exactly where she goes when she disappears for several days and I am hoping to document every aspect of her stay in Gloucester. She has been spotted at several locales in East Gloucester, Salt Island, and Twin Lights but, if by chance, she is a regular visitor to your yard, please write and let me know. The best way to keep the information from becoming public knowledge is to email me at kimsmithdesigns@hotmail.com. I am also looking for a few minutes of footage of a Great Horned Owl (Bubo virginianus) as they are closely related to Snowies (Bubo scandiacus), so please write and let me know if you have a resident Great Horned Owl. Thank you so much for any leads given 🙂

HOW CAN THE BEATING WINGS OF A SNOWY OWL BE QUIETER THAN A BUTTERFLY’S WING BEATS?

Snowy Owl Hedwig Preparing for Take-off

Several times Hedwig has flown so close that I can feel the swooshing wind around her, but I wondered, why her wingbeats are virtually soundless. I have audio recordings of comparatively tiny Monarchs, whose wingbeats are a thousand times louder than that of Hedwig’s wingbeats.

Snowy Owls, like all owls, have evolved with specially designed wings that enable them to fly soundlessly, a necessary feature for stealth hunting of small mammals such as mice, lemmings, voles, shrews, and rats. Their wings are disproportionately large to their body mass, which allows for slow flying, as slowly as two miles per hour, a sort of glide-flying, with very little flapping needed.

Additionally, comb-like serrations on the leading edge of an owl’s wingtips break up the air that typically creates a swooshing sound, creating a silencer effect. And, too, the streams of air are softened by a velvety texture unique to owl’s wings and because of the feathery combs of the wing’s trailing edge (see illustration below).
