Snowy Owl, Chippewa County, Michigan, February 2013 |
Here's an interesting look at Snowy Owl (Bubo scadiacus) reports for November of the past seven years. 2011 was the greatest Snowy irruption in many birders' memories. I'm curious what the distribution this year means. A higher-than-usual amount of sightings, but much more clustered on the Atlantic coast. This is more reminiscent of 2008. The 2011 irruption appears centered on the Great Lakes, with a lot of that spilling over into fall of 2012 - an echo of the great irruption? So, what's going on this year, and why?
