Hancock here: Snowy Owls largely missed us this year but a huge eruption probably picked up the weather fronts, directed by the southward shifting winter jet stream and got carried to the east, causing unusual numbers in the eastern and southeastern States. Several were seen in early winter along Boundary Bay here in B.C. but I only saw one in the region I cover in my bald eagle surveys.
Here is an interesting article and how the invasion is being tracked in the east.
