If you step outside during the day in Copper Harbor, your birding. There is not a bad birding spot as you can catch some species or another just about everywhere. However, there are some great trails which offer a variety of features making several habitats accessible (and convenient). All the summer trails are not accessible in winter. However, a good way to do some birding is on the cross-country trails and on snowshoes.
