Very large and powerful owl with obvious ear tufts, deep orange eyes, and finely streaked pale buffy underparts. Active mainly at night, but can be seen perched up on prominent lookouts at dusk, searching for prey. Can be found roosting during the day in shady canopy or caves. Pairs often duet, with the male giving a deep, resounding hoot and the female giving a hoarser, higher-pitched one. Inhabits a wide range of habitats, from forests to rocky canyons, but generally abundant nowhere.
