Nutcracker is a bird from the crow family, very alert and skittish. It inhabits vast spruce, pine, fir and mixed forests, preferably with an admixture of hazel. Its delicacy is nuts, but it also eats acorns, fir seeds, or pine trees in the mountains, it also does not disdain insects, larvae and invertebrates. In autumn, it stores nuts in various places in the forest (some in the ground, some in hollows). These industrious birds are usually unable to exhaust all the reserves accumulated for the winter, or they forget about some of them, thus contributing to the creation of diverse forest ecosystems. Nutcracker is found mainly in the mountains (Carpathians, Sudetes), islands in eastern Poland and Pomerania, and also in single sites in the Lublin region, including Roztocze. Its habitats are shrinking due to the cutting down of old forests and the creation of forest monocultures. Meeting these rare birds in Roztocze is a great event for birdwatchers.
