The rock ptarmigan can be found in several areas north of the Arctic Circle such as Russia, Sweden, Canada, and many others. They mainly feed on leaves, flowers, berries, and other types of vegetation. The chicks primarily feed on insects in addition to vegetation and prefer areas with brush for protection from predators. They are usually found on elevated sloped areas of the tundra and measure between 12-16 inches. They change colors several times a year due to molting but during the summer they will have spotted brown shades. The females lay 6-10 eggs at a time which take around three weeks to incubate.
