The grouse inhabits both hot and cold environments, and can be found in a variety of habitats like forests, moorland, shrub-land and close to rural farms.
In order to survive the bitter Northern winters, the grouse has feathered legs and toes which not only help to keep the grouse warm, but they also give the grouse more grip and stability when it is walking around in the snow.
Despite inhabiting areas that often fall within the Arctic Circle, thousands of grouse are hunted as game each year by humans. The grouse population numbers are not drastically effected however as they often lay a large number of eggs so the grouse population is able to increase at a fast rate.
The grouse is an omnivorous animal meaning that it eats both plants and other animals. Despite this though, plant matter makes up the majority of the grouse's diet as the grouse eats grasses, fruits, nuts, berries, shoots, seeds and flowers, along with insects and even rodents.
Due to its stocky build and the fact that the grouse is one of the few animals able to exist within the Arctic Circle, that grouse is preyed upon by a number of native predators. Wildcats including lynx, foxes, wolves and large birds of prey all prey upon the grouse, alongside human hunters.
Female grouse nests in a dip in the ground, following an elaborate mating display by the male grouse. The female grouse can lay up to 12 eggs at a time which hatch after a month of incubation.
