Snowy Owls are an irruptive species. The timing and intensity of their southward irruptions are linked to the cyclical population crashes of their prey species in the arctic- voles, lemmings, etc. Short-eared Owls probably maintain a small population in VT, with winter populations affected by snow cover. It seems unlikely to me that the frequency of Snowy and Short-eared sightings are related, but I could be wrong.

This December there has been a lot of activity in the first 5 days. What is the migration pattern for these owls? Can we expect to see a lot this winter? Do Snowy's and Short Eared Owls fly hand in hand?
