This nocturnal bird emerges at dusk from its roosting site amongst creepers to hunt from open perches (2) (3). The maned owl’s diet is not well known, but insects such as grasshoppers and beetles may be the most important prey items, although green vegetable matter has been found in the stomach of a young owl. The small weak feet and bill suggest that the maned owl is incapable of capturing larger vertebrate prey (3), as many other owls do.
Like the diet, information regarding reproduction in the maned owl is also scant. Observations in the Democratic Republic of the Congo suggest that it lays three or four eggs between March and May, in a tree cavity or an old stick nest (2) (3). Fledglings have been seen in late December and January in Cameroon and Gabon, and a pair of maned owls with full-grown young were recorded in Liberia in the third week of February (3).
