Tengmalm’s or Boreal Owl Habitat

The Tengmalm’s or Boreal Owl inhabits central and northern Europe, but its distribution is somewhat irregular. It occurs chiefly in forests but is to be found also in hill country and lowlands, preferring deep coniferous woods. It is a fairly plentiful species but escapes notice because of its concealed way of life. It often remains during the winter in its breeding grounds, descending from the mountains to the lowlands, where it roams the country-side far and wide. Some birds fly as far as southern France and northern Spain. The courting season begins in March when one can hear the male’s typical voice; sometimes this small owl may be heard also in the autumn.


In the middle of April or in May it seeks a nesting cavity, usually an abandoned woodpecker’s hole, though it will also welcome a man-made nesting box. It prefers a cavity located at a considerable height.

Boreal Owl Bird’s Breeding

The female lays 4 to 6 eggs, which she incubates herself for 25 to 31 days. The young leave the nest at the age of one month and do not return to it, but continue to be fed by the parents either on a branch or in flight.


The Tengmalm’s or boreal owl hunts small rodents such as field mice, mice and dormice, as well as other small mammals and birds. Unlike the little owl, which hunts also in the daytime, the Tengmalm’s or boreal owl ventures forth only after dusk, remaining concealed in the thick branches of spruce trees or in cavities during the daylight hours. It perches upright on the branch and flies in a direct line. The feet are thickly feathered.
