The northern counterpart for the common buzzard, the rough-legged buzzard lives on mountain tops and sparsely stocked forests. In Finland it breeds all over Lapland and in some parts of the regions of Oulu. It builds its twig nest on a ledge or a rock, in wooded areas usually preferring to nest on a pine tree or on a spruce tree. The rough-legged buzzard easily detects any threats to its nest in open terrain, making false attacks to distract the attention of the intruder.
The rough-legged buzzard is a protected species.
ADAPTING TO THE WINTER
The rough-legged buzzards use their excellent eye sight to prey on animals. In the winter they mainly feed on voles and lemmings, which are hiding well under the snow. From Finland the rough-legged buzzard migrates to Central and Eastern Europe for winter grounds.
