Hornbills show considerable variation in size. They live mainly in the forest canopy, rarely feeding on the ground. The lining is made with bark flakes brought by the male. And after hearing them call further up the valley most of the trip, I finally caught a glimpse of a helmeted hornbill (Buceros vigil).

A group of white-crowned hornbill (Berenicornis comatus). The adult male has sooty-brown plumage on the upperparts, head, chin, throat and breast. Today, however, they are just as likely to be woken by the sound of chainsaws and falling trees. Usually solitary or in pairs, occasionally small flocks. Hornbills may be the most widely represented bird in the diet and the black-casqued wattled hornbill (Ceratogymna atrata) reacts strongly to both the call of crowned eagles and the alarm calls of monkeys specified to the eagles (which are separately identifiable from the monkey's leopard-related alarm calls to both humans and, apparently, hornbills). The Crowned Hornbill feeds mainly on arthropods and also takes fruits during the dry season. Hornbills are a family of bird found in tropical and subtropical Africa and Asia . The Crowned hornbill occurs from the DRC and Ethiopia to southern Africa, where it is locally common in a wide variety of forest and woodland habitats. The female moults flight feathers and rectrices while she is in the cavity. The throat skin is dull yellow. We also predicted that hornbills would pro-duce alarm calls to alert others to the presence of the predator (Frankenberg 1981) or to signal that it has been detected (the ‘perception advertisement’ hypothesis; Curio 1978). BEHAVIOUR:   Crowned Hornbill (Tockus alboterminatus). The Crowned Hornbill is widespread in the Eastern Cape, Kwazulu-Natal and the lowveld of Mpumalanga and Limpopo Provinces, where it inhabits inland, coastal, mountain and riverine forests. They are resident (non-migratory) within their natural range. Call is a long series of high, piping notes. It wanders according to the food resources, and in response to local disturbances. Breeding in Africa: c, w; can be seen in 23 countries. Hornbills are a group of birds whose bill is shaped like a cow's horn, but without a twist, sometimes with a casque on the upper mandible. Unlike many other hornbills in its range, forages primarily at lower levels in the forest, frequently descending down to the ground.

The yellow-casqued hornbill is one of the largest birds of the West African forest, with adults weighing up to 2 kg (4.4 lb). Depending on the area of the bushveld you visit, different species can be in abundance, but the main species that we are familiar with at Londolozi are the southern yellow-billed, southern red-billed, and African grey hornbill, as well as the largest and most endangered of them all, the southern ground hornbill. Then, the female uses her own droppings for sealing the entrance. Sd : Krontoko Eccentric-looking hornbill with a bushy, upright white crest and a white tail. Often in small flocks. Hornbills occasionally fly from one branch to another in the trees overhead, while a Crested Serpent Eagle whistles as it soars above the river.

The Silvery-cheeked Hornbill is largely frugivorous (fruit eating), preferring cherry-sized fruits with hard stones. Length: 50 cm The White-crowned Hornbill (Berenicornis comatus), also known as the White-crested Hornbill (leading to easy confusion with the African Tropicranus albocristatus), is a species of hornbill found in forests in the Thai-Malay Peninsula, Sumatra and Borneo. The flight is usually direct and undulating. The order Bucerotiformes contains two suborders: Buceroti (hornbills) and Upupi (hoopoe and wood hoopoes). The call is a series of loud high pitched whistling notes, very different from the Trumpeter Hornbill?s crying baby call. approaching it and emitting calls. The chicks hatch 2-4 days apart. This bony is called a casque. Has little overlap in range with similar hornbills, and is unique in having a yellow eye. Fr: Calao couronné Within these regions, they inhabit both woodlands and savannas.

Nd : Kuiftok The bill is dark orange-red with a casque on the upper mandible. Comprehensive life histories for all bird species and families. In their habitats you can find them either in pairs or family groups. It typically moves around in pairs or small family groups. The Crowned Hornbill is sedentary in stable evergreen forest, but during the dry season, they wander in flocks of up to 80 birds after the breeding season, and reach more deciduous habitats. This work can last from some hours to several days. Southern ground hornbills are carnivorous and mostly hunt on the ground, wher Males and females are similar, but male has a bigger casque on top of the bill. It consumes snails, small birds, lizards (chameleons), and golden moles (Chrysochloris).

Puff-backed Bulbuls cheerfully sing as they discover the giant fig tree, and a Black-crowned Pitta calls softly in the distance. The genus Tockus includes the African species, the smallest of all hornbills. Along with the hornbill call is a distinctive sound of the afternoon in Borneo’s forest – the grinding, mechanical rhythms of the cicada species Dundubia vaginata. VOICE: SOUNDS BY XENO-CANTO The juvenile shows white flecks and buff edges on the wing-coverts. Has little overlap in range with similar hornbills, and is unique in having a yellow eye. Their plumage is black and white; the head, neck, breast and tail are white, while the remaining plumage is black. It consumes numerous fruits, and also crops (oil palm – Elaeis guineensis), peanuts, maize and bananas. The pair-bonds are for life and both mates are territorial. She incubates during 25-27 days.

Fairly similar to Monteiro’s Hornbill, but lacks white in the wings, and has small white corners to the tail rather than completely … The white corners of the tail are conspicuous in flight. In flight note narrow white hind edges to the mostly dark wings; the similar Black-and-white-casqued Hornbill has a very broad white … As all hornbills, they nest in cavities into which the female immures herself as soon as she is in laying conditions. FLIGHT: The laying occurs at the beginning of the rainy season, between October and January in C and S Africa, and February-July or September-November in E Africa. Found in lush woodland, forest, and forest edge. REPRODUCTION: Yellow-crowned Barbets call repeatedly in the second half of this track. Males and females are similar, but male has a bigger casque on top of the bill. The white corners of the tail are conspicuous in flight.

It can be surprisingly inconspicuous while eating large fruit in forest trees, but in flight it has noisy wingbeats and a far-carrying baby-like wailing “whaaaaaa waa waa” call. The birds are occasionally preyed upon by Crowned Hawk-eagles, and they respond to the presence of an eagle (sometimes indicated by its characteristic shriek) by mobbing, i.e. It also be found in open fields and may enter gardens in urban areas. While the exact function is unknown, it may act as an echo chamber that allows the hornbill’s call to be heard at great distances. The other species of the genus Bucorvus found in Africa is the Abyssinian ground hornbill, B. abyssinicus. The Crowned Hornbill forages among the foliage in tree canopy. Found in lush woodland, forest, and forest edge. Call is a long, insistent series of piping notes. Yellow-casqued hornbills (Ceratogymna elata) are vulnerable to predation by crowned eagles but are not preyed on by leopards and might therefore be expected to respond to the Diana monkey eagle alarm call but not to the leopard alarm call.
