I can tell you all the habitat types in Voyageurs National Park. Koochiching county supports a wide variety of owls. You can spot a great horned owl, snowy owl, barred owl, and great gray owl. Along with other special types of owls. They are on the edges of clearings. They roost in a tall tree and scan for anything they can ambush and eat.
Additionally there are many hawks that also hunt in the area. There are sharp shinned, broad-winged, red-tailed, rough-legged and northern hawk.
There are some songbirds that spend the winter there too. black-capped chickadees are the most common. Ruffed grouse are about the most common larger upland bird spending the winter here.
The snowshoe and cross-country ski trails offer easy access to the forests. you can spot any of these birds here. The Tilson Creek trail system offers a lot of opportunity along with the Black Bay ski trail system.
I spot a lot of White-Tail Deer on the trail between the Rainy Lake Visitor Center and Minnesota 11 East. The Rangers at the visitor Center spotted a wolf there too, exciting! and it was rare white timber wolf at that. The Black Bay ski trail comes across a beaver pond where some people have spotted a moose. but moose are very reclusive. People exploring the Rainy Lake Ice Road have seen a white-tail deer and a wolf pack crossing the ice.
