Owls are among us

2015 Update: And spring brought reports of owlets, including three celebrities from a nest in Lions Park.

In late November, Mark and I became aware that a flock of crows, also known as a murder of crows, was convening just before sunset in a neighbor’s big spruce tree.

They were very loud, very raucous, as if they were a lynch mob yelling for noose justice.

Our double-paned windows are somewhat of a sound barrier, but when we let the dog out, we were bombarded with enough noise to overwhelm a backyard cookout.

Was there an owl roosting in the spruce? It’s a big tree, probably planted when the neighborhood was new 50-60 years ago, so you can’t easily see inside, even when standing beneath it.

Or had the crows decided to establish a roost in our neighborhood? That was an unbearable thought.

Thanksgiving morning, while I was out sweeping up sunflower seed hulls from under our bird feeder and throwing the ball for the dog, the crows sounded even more agitated—gathered in a spruce even closer to our house. “There must be an owl within those thickly-needled branches,” I thought. “And he isn’t getting any sleep after a night of hunting.”

The next morning, just before sunrise, I lifted the window shade and saw a lump on the bare branch of our big green ash tree. Yep, a great horned owl. I told the dog she would have to wait a few minutes before she could go out.

The owl was perched about a foot away from a small squirrel nest made of dry leaves stuffed into a vortex of small branches. Leaving the kitchen lights off, I pulled out my binoculars and there was just enough light to see which way the owl was facing. It wasn’t surprising that it was facing the squirrel nest, bobbing its head up and down in a circular way, to get a better fix on a squirrel probably trying desperately not to be heard breathing.

There’s a bigger nest, or drey, on the other side of the alley. Ours looks like it is barely big enough for one squirrel, much less the three scampering around our yard every day, teasing the dog.

I was surprised that the owl didn’t just poke a taloned foot or sharp beak into that pile of leaves. But great horned owls prefer to feed in openings where they can perch and then wing after prey they hear or see, and pounce, pinning it to the ground. Eventually, this owl spread its wings and flew off.

No more mobbing crows here, however, owls have come up in recent conversations with two women I know, one living east of town and one on the northwest edge of Cheyenne. Both women were pretty sure their local owls were knocking off rabbits, the great horned’s favorite food. And both women seemed fine with that, noting that there seemed to be bunny abundance this year.

I’ve talked to my share of folks who complain when an avian predator grabs a meal, especially if the prey is a cute songbird or furry animal. So in addition to getting reports on owl activity, it was gratifying to hear people appreciate owls, even for their feeding habits.

If you are connected to any sources of birding news, you know that this winter there is another irruption of snowy owls, but in the Northeast and upper Midwest, rather than the Great Plains, as it was two years ago. Another shortage of lemmings in the Arctic, forcing them south, I guess.

Snowy owls like to be out in the open, being birds of the tundra, even if it’s the middle of the day, making them relatively easy to pick out when there isn’t too much snow acting as camouflage.

So how many great horned owls are among us, shrouded in a cloak of nocturnal invisibility or daytime coniferous cover? What about the smaller, less common owls of southeastern Wyoming: eastern screech-owl, long-eared owl, short-eared owl?

Is there a great horned owl in your neighborhood? Look for the signs: angry crows, the odd rabbit leg on the sidewalk, a large bird flashing through the beam of your headlights, and even the chunky silhouette, the size of Harry Potter’s snowy owl, in a tree or on a fencepost at dawn or dusk.

Don’t begrudge your dog’s request to be let out on a winter’s evening or just before dawn. Follow and take a look around.
