Owl be seeing you in the polar vortex

Updated Jan. 21, 2015, April 19, 2014

OK, here goes. Wacko theory No. 8,634.

Much of the eastern United States suffered some heavy winter weather this year, largely blamed on something called the polar vortex. That is a combining of elements involving the jet stream the positioning of high pressure centers in the cold north and warmer weather far offshore to the south. In my limited knowledge I don't think it's fair of me to explain it much beyond that.  However there will be links below to places that will.

Earlier in the winter, in November and December, people began spotting snowy owls way south of their usual habitat. Normally they nest in Arctic regions and migrate south for the winter but generally stay north of 60 degrees latitude.  Anchorage, Alaska is at about 60 North. This year there were sightings throughout the midwest and as far east and south as Virginia. It struck me that these two events might have something in common.

I remember suggesting to one friend she overlay a map of the vortex onto a map owl sightings, but I never heard back. So, today I gave it a try and look what I came up with. The map on the left below is of the vortex; the one on the right is snowy owl sightings in November and December. Coincidence? Ha, I don't think so. Of course there are exceptions but it sure looks like the snowy owls congregated just where the vortex was gong to show up later.

Now, taking it a step further, could the snowy owl migration pattern have been a harbinger of the polar vortex that was about to slam the eastern United States.  Could they be the wooly bear caterpillars of the bird world?

Years ago I read an article in Sports Illustrated magazine written during the construction of the trans-Alaska pipeline. In it the author wrote of his fascination with bananas on a dining hall table on the Arctic Coast of Alaska. He noted that in nature when an animal appears far outside its normal habitat, it's an indication the herd is in trouble. And then he's looking at humans and bananas in the Arctic and wondering if our herd was in trouble.

Were the owls such a warning? Is the snowy owl in trouble for some reason? Was there a low point in their normal prey species? Were they just trying to be friendly alarmists to warn people of the coming harsh winter? What else could be going on? One would take a whole new wacky theory and I am only good for one a day. But consider this, Alaska is in the weather path for winds to bring radiation from Japan. Ponder that one for a while. Meanwhile I am sticking with the owls simply going where they were most comfortable, and willing to go so far as to guess they have some indicator that helps them anticipate what winter is going to do and they act accordingly.

The point here, though, is not the speculation about why it happened or theories about motivation. The point is simply the observation that snowy owls showed up ahead of time in the same areas where the polar vortex later brought its storms.

But we have a warning for those folks on the East Coast. We are going to be wanting our owls back, and soon.

A BIT OF AN UPDATE: Some comments have shown up, several saying the change in migration is due to a change in prey species. One said voles were down in the Arctic while another blamed a decline in the lemming population. That makes sense. That, however doesn't change the basic premise pointing out the correlation between the owl migration and the location of the polar vortex. Perhaps it's the lemmings or voles that signal the change in weather pattern. There a couple of new links to articles about the phenomenon below.

ANOTHER UPDATE: That snowy owl a commenter on here mentioned, the one who was rescued after it was hit by a bus in Washington, D.C., was scheduled to be released today (4/19) in northern Minnesota. Here's that story. There were other rescues, too, at least two, one in Cleveland and another in Portland, Oregon.

What's a polar vortex?


  1. I read there was a bumper crop of baby snowy owls this year. This year one of the southern venturers found himself a perch on an awning on K Street in DC. Unfortunately while swooping down to catch a rat, the owl was hit by a city bus. But happy ending, he was taken to the zoo, treated and will be released back into the wild. I guess he will have to decide then if he is for the North or the South.

  2. We had the snowy owls here as well...

    Back in the fall, when the local farmers sent ducks off to process the butchers noted that ALL the birds had huge layers of fat around the muscles, which they believed would mean a very cold winter...

    I also found a wooly bear this fall with no stripe, all brown...

Things sports announcers say

"… there's a fearlessment about him …"

"He's got to have the lead if he's going to win this race."

"Kansas has always had the ability to score with the basketball."

"NFL to put computer chips in balls." Oh, that's gotta hurt.

"Now that you're in the finals you have to run the race that's going to get you on the podium."

"It's very important for both sides that they stay on their feet."

This is why you get to hate sportscasters. Kansas beats Texas for the first time since 1938. So the pundits open their segment with the question "let's talk about what went wrong." Wrong? Kansas WON a football game! That's what went RIGHT!

"I brought out the thermostat to show you how cold it is here." Points to a thermometer reading zero in Minneapolis.

"It's tough to win on the road when you turn the ball over." Oh, really? Like you can do all right if you turn the ball over playing at home?

Cliches so imbedded in sportscasters' minds they can't help themselves: "Minnesota fell from the ranks of the undefeated today." What ranks? They were the only undefeated team left.

A good one: A 5'10" player went up and caught a pass off a defensive back over six feet tall. The quote? "He's got some hops."

Best homonym of the day so far: "It's all tied. Alabama 34, Kentucky 3." Oh, Tide.

"Steve Hooker commentates on his Olympic pole vault gold medal." When "comments" just won't do.

"He's certainly capable of the top ten, maybe even higher than that."

"Atlanta is capable of doing what they're doing."

"Biyombo, one of seven kids from the Republic of Congo." In the NBA? In America? In his whole country?

"You can't come out and be aggressive but you can't come out and be unaggressive."

"They're gonna be in every game they play!"

"First you have to get two strikes on the hitter before you get the strikeout."

"The game ended in the final seconds." You have to wonder when the others ended or are they still going on?

How is a team down by one touchdown before the half "totally demoralized?"

"If they score runs they will win."

"I think the matchup is what it is"

After a play a Houston defender was on his knees, his head on the ground and his hand underneath him appeared to clutch a very sensitive part of the male anatomy. He rolled onto his back and quickly removed his hand. (Remember the old Cosby routine "you cannot touch certain parts of your body?") Finally they helped the guy to the sideline and then the replay was shown. In it the guy clearly took a hard knee between his thighs. As this was being shown, one of the announcers says, "It looks like he hurt his shoulder." The other agrees and then they both talk about how serious a shoulder injury can be. Were we watching the same game?

"Somebody is going to be the quarterback or we're going to see a new quarterback."

"If you're gonna play running back in the SEC you're gonna take hits."

"That was a playmaker making a play."
