The vermiculated fishing owl is a species of owl in the family Strigidae. It is found within riverine forest in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Gabon, and Nigeria. This species was first described by British zoologist Richard Bowdler Sharpe in 1875 and named in honour of French naturalist Eugène Louis Bouvier.
Region
Central Africa
Typical Environment
Occurs along forested rivers, oxbows, and swamp-forests within the Congo Basin and adjacent regions. It favors quiet, slow-moving waters bordered by mature gallery or riverine forest with ample overhanging branches. Typically avoids open savanna and fast, turbulent stretches. Roosts by day in dense foliage close to water and hunts at night from low, concealed perches. Human disturbance and riparian deforestation can limit local presence.
Altitude Range
Sea level to 1200 m
Climate Zone
Tropical
Ease of Keeping

The Vermiculated Fishing Owl is a secretive, nocturnal owl that specializes in catching fish and other aquatic prey from forested rivers and streams. It perches quietly over water and snatches prey with long, unfeathered legs equipped with spicules for grip. Its fine, wavy ‘vermiculated’ barring provides excellent camouflage in dappled riverine forest light. Like other fishing owls, it relies heavily on intact riparian forest, making it sensitive to habitat degradation.
Temperament
solitary and secretive
Flight Pattern
short silent flights with strong, deep wingbeats over waterways
Social Behavior
Usually encountered alone or in pairs, especially during breeding. Nests near water, often in large tree cavities or concealed platforms in dense riverine forest. Pairs are presumed monogamous, maintaining territories along stretches of suitable river habitat. Roosts during the day in thick foliage close to the waterline.
Migratory Pattern
Resident
Song Description
A low, resonant series of hoots and booming notes, often delivered at night from a concealed perch near water. Calls may be spaced in rhythmic sequences that carry across rivers. Contact calls include softer hoots and gruffs.
