Cheryl Antonucci just spent a very cold week in Minnesota. She spent most of it looking at birds! This is of grave concern. However you will be happy to see she did see some nice mammals. And I can grudgingly admit that Great Grey Owls are worth a second glance too.
The area also seems good for Lynx.
