Omankauz Strix butleri

Pale, medium-sized owl of dry rocky country with cliffs and canyons. Dark brown above and pale with narrow dark streaks below. Eyes are yellow-orange. Rare, local, and elusive. The vocalizations include a short series of nasal hoots, a long series of low-pitched “huu” notes, and rough “vyeet” notes. Similar to Desert Owl, but usually separated by range and vocalizations. Other differences included darker overall coloration, striped rather than barred underparts, and partially dark gray facial disc.
