Strix

Strix is a genus of owls in the typical owl family (Strigidae).
This is one of the two living families of owls, the other being the barn owls (Tytonidae). Common names for "Stryx" are earless owls, though they are not the only owls without ear tufts. "Wood owl" is also used as a more generic name for forest-dwelling owls. Neotropical birds in the genus "Ciccaba" are sometimes included in "Strix".
These are medium-sized to large, robustly built, powerful owls. They do not have ear tufts and most are nocturnal woodland birds. They eat small mammals, birds, and reptiles.
