The city of Chicago is known for many things. It is known as The Windy City more for its politics than for its weather. It is well known as the home for many of the works of architect Frank Lloyd Wright. It is the home of the Merchandise Mart which is the only building in Chicago (and maybe the country) that has its own zip code (60654).
Skunks usually nest in burrows constructed by other animals, but they also live in hollow logs or even abandoned buildings. In colder climates, some skunks may sleep in these nests for several weeks of the chilliest season.
Den Sites. 1  Depending on site conditions, muskrat dens are located in banks or lodges. 2  In dams, dikes, and banks, muskrats tunnel upward from below the water surface into the soil to make dens that remain dry (Fig. 2 and 4). Bank dens range from a short tunnel leading to an enlarged nest chamber, to a long, complex system of chambers, air ducts, and entrances.
