Spotted Eagle-Owl
Bubo africanusThe adaptable owl with the piercing yellow gaze – a silent hunter of the African night.
The Spotted Eagle-Owl (Bubo africanus) is a medium-sized species of owl and one of the smallest of the eagle owls[reference:0]. It is the most common owl found in Southern Africa[reference:1] and is known for its prominent ear-tufts and striking yellow eyes[reference:2]. This adaptable bird has successfully colonised a wide range of habitats, from wilderness areas to suburban gardens[reference:3].
Spotted Eagle-Owl Quick Facts
What Is the Spotted Eagle-Owl?
The Spotted Eagle-Owl (Bubo africanus), also known as the African Spotted Eagle-Owl and the African Eagle-Owl, is a medium-sized species of owl and one of the smallest of the eagle owls[reference:4]. It was first described by the Dutch zoologist Coenraad Jacob Temminck in 1821[reference:5].
The genus name Bubo was probably derived from the owl's call "uhu" and is an ancient name that was borrowed into many languages[reference:6]. The species name africanus means 'from or of Africa', reflecting its distribution[reference:7].
Prior to 1999, the Spotted Eagle-Owl was considered conspecific with the Greyish Eagle-Owl, but it is now classed as a separate species[reference:8]. It is the most common owl found in Southern Africa[reference:9] and has successfully adapted to living in close proximity to human habitation[reference:10].
How to Identify a Spotted Eagle-Owl
The Spotted Eagle-Owl is a distinctive and easily recognisable owl. Here are its key identifying features:
- Size: A medium-sized, grey-brown owl measuring 43-50 cm (17-20 in) tall[reference:11]. The wingspan is about 1 m (100-140 cm)[reference:12][reference:13].
- Ear-tufts: Prominent tufts of feathers on either side of its head, which it erects into 'ears' or 'horns'[reference:14].
- Eyes: Striking bright yellow eyes[reference:15].
- Facial disk: Off-white to pale ochre in colour with a black outer edge[reference:16].
- Upper body: Dusky brown in colour with dark splotches on the breast[reference:17].
- Lower parts: Off-white with fine brown barring[reference:18].
- Sexes: Females and males are alike in colour and size[reference:19].
- Juveniles: Resemble adults, but their ear tufts are less distinct and they may still have some visible fluffy down feathers[reference:20].
Rare Colour Morphs
There is a rare rufous colour form, which is reddish brown, more heavily blotched and has orange eyes[reference:21]. The plumage can be fairly varied overall[reference:22].
Distinguishing from Similar Owls
The Spotted Eagle-Owl can be confused with the Cape Eagle-Owl (Bubo capensis). The Cape Eagle-Owl is a larger bird (48-54 cm)[reference:23] and is more rufous-brown rather than grey, with orange eyes rather than yellow[reference:24]. However, the surest way to distinguish them is by looking at the breast pattern: the Spotted Eagle-Owl has fine barring, while the Cape Eagle-Owl has black and chestnut blotching[reference:25].
Behavior & Social Life
The Spotted Eagle-Owl is mostly active at night and before sunset[reference:26]. It is a territorial bird that pairs for life[reference:27].
Roosting
- Daytime roosts: During the day it roosts in trees, along cliff ledges, under bushes, in abandoned buildings, or in burrows of other animals[reference:28]. When roosting in trees, it sits close to the trunk with feathers compressed, eyes closed, and ear-tufts erect[reference:29].
- Serengeti roosting: In the Serengeti, Spotted Eagle-Owls are never found in cavities. Instead, they roost either in tree crowns or on the ground near or on large rocks such as kopjes[reference:30].
- Inconspicuous roosting: While roosting they make themselves as inconspicuous as possible, drawing their feathers tightly to their body and closing their eyes to hide any telltale glint[reference:31].
Communication
- Call: The call is a mellow hoot[reference:32]. Males usually give a double hoot, "hoo-hooooee", which the female answers with a softer triple hoot, "hoo-hoo-hooee"[reference:33][reference:34].
- Visual cue: When calling, a white patch on the throat becomes briefly conspicuous at each hoot[reference:35].
- Seasonal calling: They are most vocal in the months leading up to the breeding season, from May to August[reference:36].
- Chick calls: Chicks call for food with a loud screech-like hiss and hiss and click their beaks if threatened[reference:37]. The young do not hoot until they are effectively adult[reference:38].
Social Bonds
Breeding pairs sometimes roost together, engaging in billing and allopreening[reference:39]. They are monogamous and mate for life[reference:40].
Habitat & Distribution
The Spotted Eagle-Owl occurs in a wide variety of habitats across sub-Saharan Africa and the Arabian Peninsula[reference:41].
Key habitat types include:
- Woodlands, savannas and grasslands – the primary habitats[reference:42].
- Shrublands, semi-deserts and rocky hills[reference:43].
- Thorn savanna[reference:44].
- Suburban gardens and urban areas – they have adapted to living with people and are found in towns and cities[reference:45].
Distribution: Spotted Eagle-Owls are the most common species of owl found in Southern Africa[reference:46]. They occur throughout Sub-Saharan Africa[reference:47] and the Arabian Peninsula[reference:48]. Their range extends across sub-Equatorial Africa to southern Arabia[reference:49]. They have a healthy population in most parts of the region[reference:50].
Urban adaptation: They are often referred to as urban owls and will live in close proximity to human habitation[reference:51]. They nest on or in buildings, on window ledges, or in owl boxes provided by people[reference:52].
Tanzania Distribution
In Tanzania, the Spotted Eagle-Owl is found in various national parks and conservation areas. It has been recorded in Serengeti National Park (particularly in the Mara region and around kopjes)[reference:53][reference:54], Ngorongoro Conservation Area, Tarangire National Park, and Ruaha National Park.

Best Time to See Them
Spotted Eagle-Owls are resident year-round. They are most active at night and before sunset[reference:59], and are most vocal in the months leading up to the breeding season from May to August[reference:60]. The dry season (June to October) generally offers the best wildlife viewing opportunities.
Diet & Feeding
The Spotted Eagle-Owl is an opportunistic carnivore with a varied diet.
Food Sources
- Rodents and small mammals: The main prey[reference:61]. They help control rodent populations.
- Birds: Up to the size of terns and falcons[reference:62].
- Insects: Beetles[reference:63], termites[reference:64] and other arthropods.
- Other arthropods: Spiders and other invertebrates[reference:65].
Hunting Behavior
From a perch, they scan the ground for movement, using both their eyes and ears to detect it, flying silently in pursuit of whatever suitable prey they see[reference:66]. They are nocturnal hunters, though they may also hunt at dusk[reference:67].
Breeding & Life Cycle
The Spotted Eagle-Owl is monogamous and mates for life[reference:68]. They can breed at around one year of age[reference:69].
Nesting
- Nest site: Nests in many different places, most commonly on the ground among rocks, under shrubs, in trees, tree hollows, cliff ledges, quarries, man-made structures, or eroded banks[reference:70].
- Nest construction: A shallow ground scrape, often located under a bush, among rocks, or on a slope[reference:71].
- Alternative nests: May also use old nests of other birds, such as raptors or Hammerkops[reference:72].
- Clutch: Usually two to three white eggs, laid at intervals of one to four days[reference:73].
- Incubation: The female incubates the eggs while the male provides food[reference:74]. Incubation period is 30-32 days[reference:75].
Chicks
- Hatching: Chicks hatch blind and begin to open their distinct yellow eyes after seven days[reference:76].
- Exploration: Young start leaving the nest and exploring at about four to six weeks[reference:77]. Young spotted eagle owls leave their nest about 5 weeks after birth[reference:78].
- Parental care: Parents continue to care for the young for a few more weeks before they become fully independent[reference:79][reference:80].
Breeding season: In Tanzania and Kenya, breeding occurs throughout the year with a concentration between July and February[reference:81]. In southern Africa, breeding typically begins in July and continues to the first weeks of February[reference:82].
Conservation Status
The Spotted Eagle-Owl is assessed as Least Concern on the IUCN Red List[reference:83] and is one of the most common owl species in Southern Africa[reference:84].
Population: They have a healthy population in most parts of their range[reference:85]. The species is listed on CITES Appendix II[reference:86].
Threats: While the species is not currently endangered, habitat destruction and environmental pollution pose ongoing threats to their habitat[reference:87].
Due to their adaptability, these owls have maintained a stable population throughout their distribution[reference:88]. Continued conservation efforts are needed to monitor and protect their populations[reference:89].

Did You Know?
The Urban Owl
Spotted Eagle-Owls are often called 'urban owls' because they have successfully adapted to living in close proximity to human habitation[reference:100].
Mates for Life
These owls are monogamous and mate for life, forming strong pair bonds that last for many years[reference:101].
Ear-tufts Are for Show
The prominent 'ears' or 'horns' are actually just tufts of feathers for display and have nothing to do with their ears or hearing[reference:102].
Rare Rufous Form
There is a rare rufous colour form of the Spotted Eagle-Owl, which is reddish brown and has orange eyes instead of yellow[reference:103].
Kopje Roosters
In the Serengeti, Spotted Eagle-Owls roost either in tree crowns or on the ground near large rocks such as kopjes[reference:104].
Silent Hunters
They fly silently in pursuit of prey, using both their exceptional eyesight and hearing to detect movement[reference:105].
There is a quiet, ancient wisdom in the gaze of the Spotted Eagle-Owl. Its yellow eyes, fixed and unblinking, seem to see through the darkness of the African night with effortless clarity. It is a master of patience, sitting motionless for hours, waiting for the faintest rustle of a rodent in the grass below. In a world that never stops moving, this owl reminds us of the power of stillness – of watching, waiting, and striking with perfect precision when the moment is right. It is the silent guardian of the night, the unseen hunter that keeps the balance of the savanna in check.
