Band-bellied Owl

The band-bellied owl is fairly large, ranging from 44 to 48 cm (17 to 19 in) long. An analysis of the weight of 13 birds of both sexes showed a range of 590 to 1,250 g (1.30 to 2.76 lb) and an average of 873 g (1.925 lb). The adult has a dark brown facial disk and white "brows" over dark reddish brown eyes. Its upperparts are dark chocolate brown with scattered buffy-white spots. The tail is also dark brown, with thin white bars. The upper breast is reddish brown with buff barring. The rest of the underparts are white to creamy with reddish brown barring. Voice: The band-bellied owl's vocalizations are also poorly known. It is "aid to give a short, deep trill followed by fast burst of popping notes", and "deep, muffled hoots" have been recorded in Peru. The sexes perform duets.
