[2] Verreaux's eagle lives in hilly and mountainous regions of southern and eastern Africa (extending marginally into Chad), and very locally in West Africa, the Arabian Peninsula and the southern Middle East. In both the southernmost, from the western cape of South Africa, and northernmost, a partial study of the foods at nests in central Mali, food studies for this species have found hedgehogs to be the most significant contributor of biomass in Verreaux’s eagle-owl nests. One ringed 9-month-old moved 24 km (15 mi) away from its nest area and was thus seemingly fully independent. [50] In the Walter Sisulu National Botanical Garden of South Africa, the primary prey found around nests after a perceptible hyrax decline has become helmeted guineafowl and francolins, followed by cane rats, rabbits and dikdiks (Rhynchotragus ssp.). [84] In the Matobo Hills, persistent intrusion by an unmated adult into a pair's nesting territory seemed to have an adverse effect on nesting success. [23] Density of breeding pairs varies from 1 pair per 10.3 km2 (4.0 sq mi) in the Matobo Hills, Zimbabwe, 1 pair per 24 km2 (9.3 sq mi) in the Karoo, 1 pair per 25 km2 (9.7 sq mi) in East Africa, 1 pair per 28 km2 (11 sq mi) in the Bale Mountains of Ethiopia to a known maximum spacing of 1 pair per 35 to 65 km2 (14 to 25 sq mi) in the Magaliesberg and Drakensberg ranges. Per Konig & Weick (2008), the species with studied genetic markers found to be most closely related are a dark-eyed species pair of Asian eagle-owls, the spot-bellied (Bubo nipalensis) and barred eagle-owls (Bubo sumatranus) but these are not particularly closely related to the Verreaux’s. [73] African hawk-eagles (Aquila spilogaster) may also take a few hyraxes, but are likely to avoid direct conflicts with their much larger cousins, so will tawny eagles (Aquila rapax). Existent reports of this species building its own nest are certain to be dubious, as no known living owl builds a nest and only a small handful of owl species have been verified adding a small amount of nesting material to an existing surface or nest. Verreaux’s eagle-owl are likely to give martial eagles a respectful amount of space during daytime and there are no records of the two species harassing one another. 1999. In northeastern South Africa, the local breeding population is estimated to include 240 pairs, while the western Cape region of the country may hold possibly more than 2,000 pairs. A lovely capture, monkir. They also range into riverine forest adjacent to savanna and small, semi-open woodland surrounded by open country, though they are less likely to inhabit heavily wooded habitats. Although somewhat larger and more powerful, the martial eagle is relatively less nimble in the air and there is a case where a martial eagle was robbed of rock hyrax prey by a Verreaux's eagle. } KC Foggin; Nov 9, 2020; Another great Owl Image and so beautifully captured! In the Bale Mountains of Ethiopia and possibly in some parts of the Arabian Peninsula and the southwestern edge of the Middle East, the ranges of the golden and Verreaux's eagles overlap, but the golden is a mostly brown bird and shares none of the Verreaux's black plumage. In one case, a pair of eagle-owls nested on top of a hamerkop nest while the interior of the nest was occupied by Egyptian geese (Alopochen aegyptiacus), an unusual aggressive species of waterfowl that uses nests built by other species. [23], Of the two species regularly taken, the yellow-spotted rock hyrax can weigh from 1 to 3.63 kg (2.2 to 8.0 lb) with an average of 2.4 kg (5.3 lb), although specimens from Zimbabwe are noticeably heavier and larger than specimens from Serengeti National Park. In one study, 4 males were found to have averaged 1,704 g (3.757 lb) while 6 females averaged 2,625 g (5.787 lb). Monkeys are also predated opportunistically. The largest known rodent prey is the South African springhare (Pedetes capensis) at an average adult weight of 3,040 g (6.70 lb). Brown, L. H., Gargett, V., & Steyn, P. (1977). It is not until they are about 5 months old do most young Verreaux’s eagle-owl show the ability to capture prey for themselves. Various upland birds recorded as prey include the 177 g (6.2 oz) Namaqua sandgrouse (Pterocles namaqua), the 350 g (12 oz) rock pigeon (Columba livia), the 84 g (3.0 oz) laughing dove (Streptopelia senegalensis), the 169 g (6.0 oz) Senegal coucal (Centropus senegalensis), the 49 g (1.7 oz) scaly-throated honeyguide (Indicator variegatus) and several species of hornbill, ranging in size from the 139 g (4.9 oz) northern red-billed hornbill (Tockus erythrorhynchus) to the 1,235 g (2.723 lb) silvery-cheeked hornbill (Bycanistes brevis). Even among the Bubo owls, most species of which are known to be highly opportunistic predators with indiscriminating diets, the Verreaux’s eagle-owl is a particularly opportunistic predator. Rarely, snakes and lizards may also be taken and even termites have been eaten by this species. Most other mammalian prey recorded or inferred as hunted by Verreaux’s eagle-owl tend to be considerably larger. [9] The yellow coloration of the cere (the bill is gun-metal grey), eye-ring and “eye-brows”, all stand out in contrast to the black plumage. Cape hyrax, weighing from 1.8 to 5.5 kg (4.0 to 12.1 lb) with average of around 3.14 kg (6.9 lb), can be even larger than the Verreaux's eagles themselves, so can be more difficult to kill. } Ramadan-Jaradi, G., S. P. Waterbury, and M. Ramadan-Jaradi. It also rivals the martial and golden eagles as the largest extant member of the "booted eagle" clan. During the incubation and brooding stage, the male usually roosts near the nest during the day while the female continually sits about the nest. [9], Verreaux's eagle has specific habitat requirements and is rare outside of its particular habitat type. In both sexes, the tarsus has measured 73 to 86 mm (2.9 to 3.4 in) and the bill (in a small sample) 51 to 54 mm (2.0 to 2.1 in). [15] Unlike the other two big African eagles, they do not often partake of much carrion, so are at little risk of poisoning from carcass left out to control jackals. Verreaux’s eagle-owl is considered an avian apex predator, meaning it is at or near the top of the food chain and healthy adults normally have no natural predators. (function() { This species hunt predominantly in early evening, however they have been observed to swoop on prey during daylight.
