With their dark, almost black, plumage and long, close-set ear-tufts (that look like horns), the Stygian Owl is arguably the most “diabolical” of owls. The Stygian Owl (Asio stygius), is named after the River Styx, which of course in Greek mythology was the gateway to the afterlife. Indeed, in part because of their nocturnal haunts and human-like faces, owls have a symbolism of death and/or the afterlife in many cultures from all around the world; but the Stygian Owl arguably best demonstrates that imagery. As with other owl species from around the world, this species faces persecution in areas where it is believed to be a witch or an evil spirit and the population on the island of Hispaniola (A. s. noctipetens) is considered vulnerable for that reason. Despite persecution based on fear, this is surely one of the most handsome little devils anyone could encounter on a dark night!
The Stygian Owl is a member of the genus Asio, related to the Long-eared Owl and Short-eared Owl that many of my North American, Asian and European friends will be familiar with. The Stygian Owl is a couple of inches larger than either of those two species but you can certainly see the resemblance; for example, note the close-set ear-tufts as opposed to the widely parted, sometimes sideways ear-tufts of Bubo (“eagle-owls” and “horned owls”). The Stygian Owl has a deep hooting call similar to Long-eared Owl except that the notes have a hint of a disyllabic slur and slide down the scale a little. Although thought to be mostly resident, there may be some nomadism or short migratory movements since there are at least two winter records in southern U.S.A.
