Great grey owl
LIVING HABITS
The great grey owl breeds all over the northern conifer forest belt. The species can be found in Central and North Finland, except the northernmost parts of Lapland. The great grey owl prefers old conifer and mixed forests, nesting in previously used twig-nests of birds of prey. It feeds mostly on rodents. The great grey owl is not particularly tied to a certain location, but migrates to wherever it can find food most easily. The species can be active both during day and at night.
PROTECTION
The great grey owl is a protected species on nature conservation areas.
ADAPTING TO THE WINTER
The great grey owl boasts a well isolating, thick plumage. With its excellent hearing it detects a vole from under the snow, catching it in no time into its mouth.
