Hawk owls breed on the coniferous forest belt around the northern hemisphere. Even in Finland it is a northern species, not to be found in the southern parts of the country. Hawk owls live mostly in open coniferous forests, and also, especially in the north, birch-tree covered mountain areas. Because hawk owls nest in holes, they prefer areas with dead standing pine trees or hollow tree-trunks. The hawk owl is active during the day. Its range of distribution depends on the number of its main source of food, namely, small rodents. When food is scarce, hawk owls migrate, and this is when the northern species can be found all the way down in the southernmost parts of Finland also.
Like our other owls, also the hawk owl is a protected species in Finland.
ADAPTING TO THE WINTER
