The boreal owl (Aegolius funereus) is a small owl. In Europe, it is typically known as Tengmalm's owl after Swedish naturalist Peter Gustaf Tengmalm or, more rarely, Richardson's owl after Sir John Richardson. The scientific name is from Latin. The genus name Aegolius is a type of screech owl thought to be a bird of ill omen, and funereus means "funereal".
