Stygian Owl

Asio stygius

Large565 gForest

The Stygian owl is 38 to 46 cm (15 to 18 in) long and weighs about 400 to 675 g (14 to 24 oz). The sexes have similar very dark plumage. (The adjective "Stygian" means "of, or relating to, the River Styx", but is more widely applied to anything that is dark or dismal.) The face is blackish with a pale border and a whitish forehead, and the head has long dark feathers that project upward as "ears". The dark upperparts have buff streaks and bars; the underparts are a dingy buff with dark brown or blackish barring and streaks. Voice: The Stygian owl's song has been variously described as "a single deep, emphatic woof or wupf", "a very low and loud hu or hu-hu", and "a muffled hoot given singly: boo". Females also give "a short, screamed rre-ehhr or mehrr" when calling to the male, and also "a short catlike miah".
