Southern White-faced Owl

About

The Southern White-faced Owl is a medium-small owl native to sub-Saharan Africa. It is characterized by its prominent ear tufts, bright orange eyes, and a distinctive white facial disc bordered by black. This species is known for its remarkable ability to compress its plumage and flatten its body to mimic a broken tree branch, aiding in camouflage.

Size & lifespan

Length

22-28 cm

Wingspan

60-70 cm

Weight

180-260 g

Lifespan

Up to 10 years in the wild, longer in captivity

Diet

Carnivore (primarily insects and small vertebrates)

Physical characteristics

Plumage

Overall grey-brown plumage with fine vermiculations and darker streaks. The underparts are paler, whitish with dark streaking. The most striking feature is the white facial disc, sharply outlined in black, with a dark grey-brown crown and prominent ear tufts. The upperparts are mottled grey-brown, providing excellent camouflage against tree bark.

Beak shape

Small, sharply hooked, and dark grey to black.

Eye color

Bright orange to orange-yellow, contrasting sharply with the white facial disc.

Leg color

Feathered legs and feet, typically greyish-brown, with dark talons.

Distinguishing features

Prominent ear tufts, bright orange eyes, and a distinct white facial disc bordered by black. When threatened, it can adopt a 'slim' posture, compressing its feathers and raising its ear tufts to appear like a broken branch. Conversely, when displaying or alarmed, it can puff up its feathers to appear larger.

Juvenile appearance

Juveniles resemble adults but have softer, fluffier plumage, less defined facial markings, and often duller eye color. Their ear tufts may be less developed.

Seasonal changes

No significant seasonal plumage changes. Plumage remains consistent throughout the year.

Sexual dimorphism

Males and females are generally monomorphic in plumage, though females tend to be slightly larger and heavier than males.

How to identify

1. 1

   Facial Disc

   Look for the striking white facial disc, sharply outlined in black, which is a key identifier for both White-faced Owl species.

2. 2

   Eye Color

   Note the bright orange to orange-yellow eyes, which stand out against the white face.

3. 3

   Ear Tufts

   Observe the prominent ear tufts, which are often held erect, especially when alert or displaying.

4. 4

   Plumage Coloration

   Identify the overall grey-brown, finely vermiculated plumage, which provides excellent camouflage against tree bark.

5. 5

   Size

   Its medium-small size (22-28 cm) helps distinguish it from larger owl species.

6. 6

   Behavioral Posture

   Watch for its unique camouflage posture: when threatened, it compresses its feathers and raises its ear tufts to mimic a broken branch, appearing very thin.

7. 7

   Vocalization

   Listen for its characteristic descending series of soft hoots, 'hoo-hoo-hoo-hoo', which fades away.

Habitat & range

Biomes

Savanna, woodlands, thornbush, riverine forests, and semi-arid areas.

Geographic range

Sub-Saharan Africa, from southern Gabon and Angola east to southern Somalia, and south to northern South Africa. Its range includes countries like Namibia, Botswana, Zimbabwe, Mozambique, and parts of East Africa.

Elevation range

Typically found from sea level up to approximately 1,800 meters.

Preferred environments

Prefers open woodlands, acacia and mopane savannas, and areas with scattered trees and shrubs. It avoids dense forests and true deserts, favoring areas with sufficient cover for roosting and hunting.

Behavior

Activity time

Strictly nocturnal, becoming active at dusk and hunting throughout the night. It roosts during the day, often camouflaged against tree trunks.

Feeding habits

Primarily insectivorous, feeding on large insects such as grasshoppers, crickets, beetles, and moths. It also preys on small vertebrates including rodents, small birds, lizards, and frogs. It hunts from a perch, swooping down to catch prey on the ground or in vegetation. It is an opportunistic hunter.

Social behavior

Generally solitary or found in pairs. They are territorial, especially during the breeding season.

Flight pattern

Silent, undulating flight with rapid wing beats followed by glides. Agile in flight, especially when hunting in dense vegetation.

Migration pattern

Resident throughout its range, though some local movements may occur in response to prey availability or environmental conditions.

Territoriality

Highly territorial, especially around nesting sites. Pairs will defend their territory from other owls and potential predators.

Breeding & reproduction

Breeding season

Varies geographically, typically coinciding with the dry season or early wet season, often between July and October in southern Africa.

Nesting habits

Does not build its own nest. It utilizes abandoned nests of other birds, particularly raptors like raptors or crows, or tree cavities. Nests are typically located in trees, often at a considerable height.

Clutch size

2-4 eggs

Egg description

Typically 2-4 (occasionally 1-5) pure white, spherical eggs.

Incubation period

Approximately 28-30 days, primarily by the female.

Fledging period

Young fledge around 30-33 days after hatching, but remain dependent on parents for several weeks thereafter.

Parental care

Both parents participate in raising the young. The female incubates and broods, while the male provides food. Once hatched, both parents hunt to feed the owlets.

Where to find

Field tips

1. Nocturnal Search. As a nocturnal species, the best time to find them is after dusk or before dawn. Use a spotlight (with caution and respect for wildlife) to scan trees for their reflective orange eyes.
2. Listen for Calls. Learn their distinctive hooting call. Listening for their vocalizations is often the easiest way to locate them, especially during the breeding season.
3. Daytime Roosts. During the day, they roost motionless against tree trunks, often in the fork of a branch or next to a main stem. Their camouflage is excellent, so look very carefully for their shape and ear tufts.
4. Look for Pellets. Check the base of large trees for owl pellets (regurgitated indigestible parts of prey), which can indicate a regular roosting site.
5. Follow Alarm Calls. Sometimes, smaller birds mobbing an owl during the day can lead you to its roosting spot.

Fun facts

• The Southern White-faced Owl's ability to dramatically change its appearance from a 'fluffy' owl to a 'thin' stick-like form is one of the most impressive camouflage displays in the avian world.
• Its bright orange eyes are highly sensitive to low light, aiding its nocturnal hunting prowess.
• Despite its small size, it is a formidable predator, capable of catching prey almost as large as itself.
• The species was only formally split from the Northern White-faced Owl (Ptilopsis leucotis) in 2007 based on genetic and vocal differences, highlighting the ongoing discoveries in ornithology.
