28-5-2019 SOMALISA CAMP, ZIMBABWE - SOUTHERN GROUND HORNBILL (Bucorvus leadbeateri)

The southern ground hornbill (Bucorvus leadbeateri) is one of two species of ground hornbill, both of which are found solely within Africa, and is the largest species in the hornbill order worldwide. It can be found in the southern regions of Africa, ranging from Kenya to South Africa. Within these regions, they inhabit both woodlands and savannas. The other species of the genus Bucorvus is the Abyssinian ground hornbill, B. abyssinicus.

Southern ground hornbills are carnivorous and hunt mostly on the ground. Their food ranges from insects to small vertebrates. Their nests are often found in high tree cavities or other shallow cavities, such as rock holes in cliff faces. These birds are a long-lived species, having lifespans in the range of 50–60 years, and up to 70 in captivity. In relation to their long lives, they do not reach sexual maturity until 4–6 years old, and begin breeding around 10 years old. Their sex can be identified by the colour of their throats: the male's is pure red and the female's is a deep violet-blue.

Southern ground hornbills are a culturally pervasive and important species in southern Africa. Kruger National Park, located within South Africa, lists southern ground hornbills as one of their 'Big Six' bird species.[6] However, their numbers have been declining, due in part to persecution, habitat destruction, cultural beliefs, and other factors. They are listed globally as 'Vulnerable' by the IUCN as of 2018, and as 'Endangered' in South Africa, Lesotho, Namibia and Eswatini.

Southern ground hornbill groups are very vocal: contact is made by calls in chorus which can usually be heard at distances of up to 3 kilometres (1.86 mi). The calls allow each group to maintain its territory, which must be as large as 100 square kilometres (40 sq mi) even in the best habitat.

Southern ground hornbills can be found from northern Namibia and Angola to northern South Africa and southern Zimbabwe to Burundi and Kenya. They require a savanna habitat with large trees for nesting and dense but short grass for foraging.

This is a large bird, at 90 to 129 cm (2 ft 11 in to 4 ft 3 in) long. Females weigh 2.2 to 4.6 kilograms (4.9 to 10.1 lb), while the larger males weigh 3.5 to 6.2 kilograms (7.7 to 13.7 lb).[citation needed] The average weight of eight females was 3.34 kg (7.4 lb) whilst that of eight males was 4.2 kg (9.3 lb); thus they average around 35% percent heavier than any Asian hornbill species.[9] Wingspan is from 1.2 to 1.8 m (3 ft 11 in to 5 ft 11 in). The wing chord is 49.5 to 61.8 cm (19.5 to 24.3 in), the tail from 29 to 36 cm (11 to 14 in), the tarsus from 13 to 15.5 cm (5.1 to 6.1 in) and the culmen from 16.8 to 22.1 cm (6.6 to 8.7 in). Stevenson and Fanshawe report that the Abyssinian ground hornbill is the larger species on average, at 110 cm (43 in), than the southern species, at 102 cm (40 in), but published maximum weights and standard measurements indicate the southern species is slightly larger. Average weights are not known for the Abyssinian species.

The southern ground hornbill is black with vivid red patches of bare skin on the face and throat (yellow in juvenile birds)—as well as being one of few birds with eyelashes—which are believed to keep dust out of the birds' eyes while they forage during the dry season. The white tips of the wings (primary feathers) seen in flight are another diagnostic characteristic. The beak is black and slightly curved and presents a casque, more developed in males. Female southern ground hornbills are smaller and have violet-blue skin on their throats. Juveniles to six years old lack the prominent red pouch, having a duller patch of grey in its place.

The southern ground hornbill is a vulnerable species, mainly confined to national reserves and national parks. They live in groups of 5 to 10 individuals including adults and juveniles. Often, neighbouring groups engage in aerial pursuits. These birds are apex predator and thus ecologically important. They forage on the ground, where they feed on reptiles, frogs, snails, insects and mammals up to the size of hares. Southern ground hornbills rarely drink. Their range is limited at its western end by the lack of trees in which to build nests.

The southern ground hornbill is an obligate cooperative breeder, with each breeding pair always assisted by at least two other birds. Experiments in captivity have found that birds without six years experience as helpers at the nest are unable to breed successfully if they do become breeders. This suggests that unaided pairs cannot rear young and that the skill gained in helping as a juvenile is essential for rearing young as an adult.

In captivity, a maximum lifespan of 70 years is recorded, and it is generally believed that the life expectancy of a bird that survives long enough to fledge is as high as thirty years or more, which is comparable to that of more famously long-lived birds like the wandering albatross.

The adult male has an extensive brilliant red face and throat wattles, while the adult female has purple-blue skin in the center of the red throat patch. The immature is scruffy with yellowish facial skin. In flight, this huge bird is black with extensive white wingtips. Family groups walk slowly through bushy savanna and grassland, foraging for large invertebrates and small vertebrates. In the early morning, dominant pairs duet with a deep-bass booming, “oooh..oooh..ooh-oh”, which can be heard several kilometers away.

15-4-2018 CHOBE NAT PARK, BOTSWANA - SOUTHERN GROUND HORNBILL (Bucorvus leadbeateri)

The Southern Ground Hornbill (Bucorvus leadbeateri), formerly known as Bucorvus cafer, is a remarkable bird, the largest in the hornbill order and found exclusively within Africa. This majestic creature, with a length ranging from 90 to 129 cm and a wingspan of 1.2 to 1.8 meters, is a sight to behold. The males, larger than the females, can weigh between 3.5 to 6.2 kilograms, while females range from 2.2 to 4.6 kilograms. They are predominantly black with striking red patches of bare skin on the face and throat, which serve to keep dust from their eyes while foraging. In flight, the white tips of their wings are distinctly visible. The beak is robust, black, and slightly curved, with a casque more pronounced in males. Females are identified by their violet-blue throat skin, while juveniles have a paler, greyish patch instead of the vibrant red.

To identify the Southern Ground Hornbill, look for its large size, black plumage, and the vivid red or violet-blue skin on the throat. The male's throat is a pure red, while the female's is deep violet-blue. Juveniles can be recognized by their duller grey throat patch. In flight, the white primary feathers are a key distinguishing feature.

The Southern Ground Hornbill is found in woodlands and savannas, requiring a habitat with large trees for nesting and short grass for foraging.

This species ranges from Kenya to South Africa, with its presence also noted in northern Namibia and Angola to southern Zimbabwe and Burundi.

Living in groups of 5 to 10, these birds are apex predators and play a crucial ecological role. They forage on the ground, hunting a variety of prey from insects to small mammals. They are known for their loud, chorus-like calls that can be heard over great distances, serving as a means of maintaining their territory.
