Tengmalm’s Owl

The Tengmalm’s Owl (Aegolius funereus) is a small owl from the typical owl family, Strigidae. It breeds in dense coniferous forests across northern North America and Eurasia, and in mountain ranges such as the Alps and the Rockies. It is known as the Boreal Owl in North America.

This smallish owl is 8.5 to 10.5 inches long and has a wingspan of 20 to 25 inches. It is brown above, with white flecking on the shoulders. Below it is whitish streaked brown. The head is large, with yellow eyes and a white facial disc, and a “surprised” appearance. Young birds are chocolate brown.

This bird takes small prey, mainly voles and other mammals, but also birds, insects and other invertebrates. It is mostly nocturnal. The female lays 3 to 6 eggs in a tree hole.

The Tengmalm’s Owl is named after the Swedish naturalist Peter Gustaf Tengmalm.
