Snowy Owls in Mid-Michigan 2018

Do you want to see a resident of the Arctic without leaving Mid-Michigan?

Right now we are undergoing an event called a Snowy Owl irruption.  During an irruption, Snowy Owls (Bubo scandiacus) descend from the Arctic in large numbers.  It is normal for some snowy owls to migrate south to southern Canada and the northern United States every winter, but during an irruption year the migration is much larger than normal. Snowy Owls have been reported this winter as far south as Oklahoma and Virginia.

Many people mistakenly believe that an irruption indicates that the animals are suffering food shortages in their native habitat and arrive weak and starving.  Instead, the opposite is probably true.  Irruption years have been linked with abundant summer food supplies allowing more young owls to successfully fledge (develop wing feathers large enough for flight) and strike out on their own.  These young owls form the majority of owls during an irruption.

While most owls are secretive and prefer to hide during daylight hours, Snowy Owl are quite comfortable hunting during the day - during the Arctic summer these birds experience nearly 24 hours of sunlight each day.  Also these birds are used to open habitats.  While most owls retreat to the security of wooded areas during the day, Snowy owls are more likely to perch on the ground in an open field, atop a building, or atop a roadside utility pole.  This visibility and their exotic nature makes Snowy Owls one of the few birds that will excite non-birders.

If you want to see a Snowy Owl, you can always just drive around and look for them, but the best way to see them is to find out where other people have been sighting them.  Ask a birder - they will know where the local Snowy Owls are hanging out.  If you lack access to a birder check out the website eBird.  Here is link for the current year's Snowy Owl sighting.  Once on the page you can zoom in to your location and see if any have been sighted nearby.  If want to see other birds, you can search for them on eBird too - just type in the search box.  Most of the Snowy Owls that I have seen were ones that were previously reported on eBird.  The owl in the second photograph above was one that I found on my own simply by observing the fields as I drove home from work.

If you go out looking for Snowy Owls please remember that these owls are best enjoyed from a distance. If the owl keeps looking at you with fully open eyes, stands erect, or takes flight then you are getting too close.
