The last big Snowy Owl invasion was in 2011 (top map), but it was much more widespread than the one underway now (bottom map). Note how it is mostly focused on the Great Lakes and the Northeast. Anyone care to throw out a hypothesis to explain the differences we are seeing between these two events? Join VCE biologist Kent McFarland tomorrow on Vermont Edition at noon to learn more about Snowy Owls and other winter raptors in Vermont.
