Snowy Owl Invasion!

The snowy owls are here -- especially if you live on the east coast! Birder extraordinaire Tim Boucher provides the latest on this natural phenomenon -- and how you can see this dramatic bird near you.

Last winter it was the finches.

This winter, especially on the east coast, it’s all about the Snowy Owls – a sudden and dramatic invasion.

The invasion has caught every one off guard – usually they occur every four years or so. Since the last one was in the winter of 2011-12, no one was expecting such a massive invasion this winter.

The reports are staggering – people in south-eastern Canada are seeing up to 200 in a day.

They’re being reported as far south as Charleston, South Carolina, and east to Bermuda (yes, in the middle of the ocean).

In my neck of the woods (the Washington, DC area), as many as ten are within striking distance – some quite close.  Airports are a favorite haunt, since there are open grasslands, favored by rodents, which are in turn eaten by the owls.

Small numbers of owls head south every year. Theories abound as to the reasons why there are such high numbers this year. But one thing we know for sure, there must have been a very successful breeding season up north as most of the birds we are seeing are juveniles.

Juveniles are usually the ones that make these dramatic movements – mostly being pushed away by stronger adults, as there is competition for food at this time of year. Later, they will be trying to find their own territories.

If you want to find out if there is one near where you live, either hop onto eBird where people have been reporting them, or find your local birding listserv and read the archives – if one has been seen, it will surely have been reported.

My advice if there is one in your area? Don’t wait; go see it immediately.

For as I learned the hard way, it might move on pretty quickly, looking for more favorable hunting grounds. And if you do see one, report it on eBird – so that scientists can gather data on this invasion.

And finally, please practice the safe birding rules – don’t get too close and don’t harass the bird (or any bird for the matter) – it has flown a long way, is stressed out, hungry, and is trying to get through the winter.

    with my respect to mr naturalist, i’m surprised that this article didn’t include more about preferred habitats other than just airports. any dope can figure out ‘go to where someone else just saw one’.
    : )

    Here in Anne Arundel county, one was spotted around Galesville last week. One was seen on the South River over the weekend, and another one was spotted yesterday on Route 2 in Edgewater.

    I may have seen one Monday morning, but it flew by so fast, I couldn’t confirm it. I’m in Arundel On The Bay.

    I’ll keep looking!

    Yet another one was spotted in Quiet Waters Park Tuesday morning or Monday evening.

    Great post, Tim, and check out this blog from an observer in Newfoundland – http://brucemactavish1.blogspot.com/

    He speculates that a great lemming year in northern Quebec and a resulting banner year for owl nesting has led to this unprecedented influx of snowies. Up here in Massachusetts, they are verywhere, and I saw 5 in one day on Plum Island 3 weeks ago.

    Many Snowy Owls have been spotted along the coast in Southern NH and Northern MA. Most recently I got the chance to photograph an individual at Salisbury Beach in MA in the salt marsh and atop a pine tree over the course of several hours on 12.19.13. There have been as many as 6 owls sighted in a single day on Plum Island and Salisbury Beach.

  6. The owl in Asheville has affectionately been named Tundra. Our Transylvania county community has rallied around her to support her as when she arrived she was emaciated and was only 1.8 pounds! She is now up to about 4 pounds. She will need to be around 6 pounds before she will be released to be sure she can survive the flight back and live successfully. The website link I’ve provided is a way to keep up with her and provide additional support. We had one fundraiser and are having another Feb 23rd that is geared more toward families. We welcome anybody who wants to come and support her. http://brenda-jean-doingtherightthing.blogspot.com/2014/01/update-tundra-has-been-moved-to-outdoor.html

  7. There was also another snowy owl in Washington DC who was seen and a week later was hit by a bus. She has a broken toe and then some head trauma. She has since been checked out by a vet and is going to be ok.
