african eagle owl call

The male utters a fast hokok-hokokokok probably associated with courtship. We saw another one, right at head height, sound asleep in a dense tree just behind the Satara Camp restaurant in Kruger (see photo below.)

[3][57] Studies in other areas have shown that, while hedgehogs are seemingly taken opportunistically, they are at best secondary as contributors of prey both in quantity and biomass. The depth and quality of the song makes confusion by sound more likely with a leopard (Panthera pardus) than any other bird. [54][55] When capturing hedgehogs, the eagle-owl descends silently with its soft-comb wings and ambushes the hedgehog by imbedding its talons about the face. Hal Brindley is a wildlife photographer, film-maker, and writer living in Asheville, North Carolina. These species are all primarily insectivores and are much reduced in the size and strength of their feet and talons compared to most other contemporary species, although the spotted eagle-owl can be locally specialized to feed on small rodents as well. Storm, G. L., Andrews, R. D., Phillips, R. L., Bishop, R. A., Siniff, D. B., & Tester, J. R. (1976). Among all the world's owls, it is fourth heaviest living owl, after Blakiston's fish owl (Bubo blakistoni), the Eurasian eagle-owl (Bubo bubo) and the tawny fish owl(Bubo flavipes), and in addition, the fourth longest living owl (measured from the … [4][5][47] In South Africa's De Hoop Nature Reserve, it was found that birds were somewhat better represented by both number, 43.3% of remains, and biomass, 57.84% of remains, than mammals or any other prey group. Adamcik, R. S., A. W. Todd, and L. B. Keith. Some of his photography can be viewed at [139][140][141][142][143] Given that the Verreaux's eagle-owl is surprisingly bold about coming to their ground to, among other things capture beetles, feed on prey too large to carry in flight or, as is likely the case in the jackal attack, drink water, it is possible that the jackal was simply able to ambush an incautious eagle-owl rather than a grounded one. The orange eyes and white facial disk differentiate the Southern White faced Owl from the Africa Scops Owl (which has yellow eyes.). Its rasping call is said to sound like the tearing of fabric.

They reach their western distribution in The Gambia, Senegal, Guinea and Sierra Leone. [5] Other fairly common, largish herons are also known to fall prey at night to Verreaux's eagle-owl including the 873 g (1.925 lb) common egret (Ardea alba), the 1,443 g (3.181 lb) grey heron (Ardea cinerea) and the 975 g (2.150 lb) purple heron (Ardea purpurea). [3][7][47], Like great horned owls, but unlike Eurasian eagle-owls, the Verreaux's eagle-owls normally uses old nests built by other birds as their own nests. [8][100][101], Other medium-sized water birds known to have been represented in this species diet include the 1,008 g (2.222 lb) yellow-billed duck (Anas undulata), the 983 g (2.167 lb) African black duck (Anas sparsa), the 596 g (1.314 lb) African swamphen (Porphyrio madagascariensis) and the 825 g (1.819 lb) red-knobbed coot (Fulica cristata). Vawda, A., Burger, F. J., & Smit, A. L. (1981). [4] Reportedly, birds in the southern part of their range appear marginally larger on average but these size differences are quite subtle and may be considered as a mild case of Bergmann's rule. [5][47][51][52], The prey type most often associated with Verreaux's eagle-owl are hedgehogs. [19] While female owls are almost always larger than males, Verreaux's eagle-owl stands out as one of the most sexually dimorphic living owl species, some studies showing the female can average 35% heavier than the male. [3] They will also sometimes run after prey on the ground, flapping their wings rapidly as they walk, or wade into shallow waters to pin down fish. [47][130] However, in some even larger birds of prey, adults as well as nestlings and fledglings have been killed. Verreaux's eagle-owl is mainly grey in color and is distinguishable from other large owls by its bright pink eyelids, a feature shared with no other owl species in the world. [138] Similar rare successful attacks on great horned owls and Eurasian eagle-owls by smaller red foxes (Vulpes vulpes) have been reported but in these cases the owls were mysteriously grounded in the horned owl and distracted by nesting into too-easily accessed sea cliffs in the eagle-owl. [3][81] Live ungulates verified to have been hunted have included piglets of common warthogs (Phacochoerus africanus), which have an average birth weight of only 665 g (1.466 lb) but grow to over 2,000 g (4.4 lb) in just a couple weeks. [7][32] The normal cause of persecution is their possible status of predators of small domestic stock, though this is certain to be rare, at least in areas with substantial wild prey populations. However hunting on the wing has been reported, even of flying insects. [3][18][21][120] While the akun is a primary forest-dweller as are the medium-sized Fraser's and Usambara eagle-owl and large Shelley's eagle-owl and thus is not likely to co-exist with Verreaux's eagle-owls except in rare cases, the northerly-distributed greyish eagle-owl (which was at one point considered merely a subspecies of the spotted) and the southerly-distributed spotted eagle-owl have much more similar habitat preferences to the Verreaux's species. [47][81][115][116], Predation on fish has been reported but no fish have been observed firsthand in dietary studies. [3][8][9][10] Based on body mass and wing chord length, Verreaux's eagle-owl is about the same size as "medium-sized" races of Eurasian eagle-owl, such as those from Central Asian steppe (B. b. turcomanus) and the Himalayas (B. b. hemachalana), slightly smaller than most northern Eurasian races, considerably smaller than Siberian and Russian eagle-owls, and somewhat larger than the smallest Eurasian eagle-owl subspecies, such as those from the Iberian Peninsula (B. b. hispanus) and the Middle East (B. b. omissus or nikolskii). (1985) feel that these generally represent cases of scavenging on carrion. Badenhorst, S., van Niekerk, K. L., & Henshilwood, C. S. (2014). As the name suggests it has small pearly spots on its head, back, tail, and wings. [4][5][61][62][63] Some larger rodents they've hunted have included the 529 g (1.166 lb) cape ground squirrel (Xerus inauris), the 786 g (1.733 lb) Gambian pouched rat (Cricetomys qambianus) and the 1,900 g (4.2 lb) lesser cane rat (Thryonomys gregorianus).
