Verreaux's Eagle-owl

Fascinating facts about the Verreaux's Eagle-owl

• Verreaux's eagle-owl dwarfs every other African owl, reaching up to 66 cm (26 in) from beak to tail. Its length spans 58-66 cm (23-26 in) and the biggest wild female recorded a wingspan of nearly 164 cm (5 ft 5 in). Females outweigh males by about a third, a 35 % difference, making it one of the most sexually dimorphic owls on Earth. Males weigh 1,615-2,000 g (3.6-4.4 lb) while females tip the scales at 2,475-3,150 g (5.5-6.9 lb); a study of four males averaged 1,704 g (3.8 lb) and six females 2,625 g (5.8 lb).
• Its voice plunges deeper than any other living owl, producing a low-pitched gwok that can travel up to 5 km (3.1 mi) on a quiet night. The male's song is so bass-rich that listeners sometimes mistake it for a leopard's growl. In Kenya the call ranks as the second deepest bird sound after the southern ground hornbill, whose croak resembles a large frog.
• Its diet is a buffet of mammals, birds, insects, with mammals making up just over half of what it eats. When a preferred prey disappears, the owl swaps to whatever size-appropriate animal it can find, showing a flexibility that lets it survive in changing landscapes. This opportunism underpins its IUCN status of Least Concern, because the bird can shift from rodents to birds to insects as ecosystems transform.
• The owl thrives across most of sub-Saharan Africa but shuns dense rainforests, preferring dry savanna with scattered trees. In the extreme north-west of its range, such as central Mali, the habitat receives less than 55 cm (22 in) of rain each year, yet the birds still need some trees for nesting and hunting, showing they can persist in semi-arid zones. Their ability to occupy riverine woodlands, floodplains and even newly planted eucalyptus shows how adaptable they are to human-altered environments.
• Verreaux's eagle-owls are opportunistic predators that hunt a variety of prey.

About the Verreaux's Eagle-owl

The Verreaux’s eagle‑owl (Bubo lacteus) is a strikingly large nocturnal raptor, rivaling the Eurasian eagle‑owl in size. Adults display a mottled tawny‑brown plumage punctuated by bold white patches on the shoulders and a broad, creamy facial disc that frames amber eyes like twin lanterns. Their massive, feathered legs end in powerful talons capable of crushing the bones of prey the size of small antelopes, while a deep, resonant hoot can travel for miles across the savanna night. This owl favors open grasslands, savannas and lightly wooded plateaus across sub‑Saharan Africa, often nesting in cliff crevices, abandoned nests of large birds, or even in the hollowed trunks of baobabs, where the cool interior provides a refuge from the scorching daytime heat. A consummate opportunist, the Verreaux’s eagle‑owl hunts from perches or in low, silent flight, preying on mammals ranging from rodents to hyraxes, and on birds as large as francolins. It also exhibits a surprising trait: occasional kleptoparasitism, stealing freshly killed prey from smaller owls and even from diurnal raptors that have dropped their catch. This boldness extends to its breeding behavior; both sexes share incubation duties, and the fledglings remain dependent for several months, learning the art of night‑time hunting under the watchful eyes of their parents, a mentorship that ensures the continuation of this apex nocturnal predator’s legacy…
