Minnesota’s Northern Owl Irruption: Winter 2024-2025

Join us to learn more about the scope and scale of the owl irruption of Winter 2024-2025 from wildlife biologist Dave Grosshuesch.

Last winter was an exceptional winter for irruptive owls in Northeastern Minnesota. Dozens upon dozens of Boreal Owls and Great Gray Owls showed up in locations and habitats where they are not normally found. It was an amazing time to see these birds, although irruptions are often incredibly difficult for birds.

For folks studying northern owls, this winter was an excellent opportunity to collect data and better understand why these irruptions happen and which birds leave their northern territories during irruption years.

Dave received a B.S. in Wildlife Management and Biology from the University of Wisconsin – Stevens Point, and a M.Sc. in Biology from the University of Minnesota – Duluth. He is a wildlife biologist for the Superior National Forest – Tofte Ranger District based out of Tofte, MN. Although he loves all things wildlife, his true passion is owls… He started working with owls while attending UW-Stevens Point and has over 30 years of varied experience researching owls, including fall migration banding, breeding season monitoring, and nest site habitat.
