The bird species in MN are changing too. There are no Blue Jays, Brown-Headed Cowbirds, or Common Grackles, & fewer Black-Capped Chickadees. The House Sparrows stay around all year of course, but new species are also heading here for the winter. There are many more Nuthatches (mostly white-breasted, but a couple of red-breasteds too), American Crows, & Common Pigeons, & I saw an American Goldfinch. I think that some of these species (namely the goldfinches & the nuthatches) don’t go anywhere during the summer, but since there is more food in the woods, parks, & by lakes & rivers when it is warm, they look for food there instead of in yards.
