Snowies About to Irrupt?

From Bruce Danz

What's this?? A Snowy Owl in NE Wisconsin in early November? I've never seen them this early. This could be a sign that we will experience a Snowy Owl irruption this winter, which means many more Snowy Owls coming south. The last irruption was in 2017-18. An irruption results from a high population of lemmings (Snowy Owl chow) in the Arctic, leading to a very successful owl breeding season, resulting in a larger number of young Snowy Owls competing for food and migrating south to find it. This is a young female.
