Distinguishing features

They have either rusty or dark gray intricately patterned plumage with streaking on the underparts. Mid-sized by screech-owl standards, they are stocky, short-tailed (tail length averages 6.6 to 8.6 cm) and broad-winged (wing chord averages 14.5 to 17 cm) as is typical of the genus. They have a large round head with prominent ear tufts, yellow eyes and a yellowish beak with average length of 1.45 cm. The feet are relatively large and powerful compared to more southern screech owls and are typically feathered down to the toes, although the southernmost populations only have remnant bristles rather than full feathering on the legs and feet.
