A bird of the family Strigidae (illustration). Total length is about 72 cm. Females are particularly large, with a wingspan of 1.8 m and weight of up to 4 kg. They are distributed over most of Eurasia except the polar regions, and over North Africa. They have been recorded as vagrants in Japan several times, but breeding in Hokkaido was confirmed in 1994. They live as resident birds in large, remote forests, rocky areas, and wastelands, and have territories all year round. Their plumage is reddish-brown or cream-colored, with irregular stripes and spots all over. Their large and powerful bodies make them the most powerful nocturnal raptors.
