Summary
[edit]DescriptionSouthern Ground Hornbill, Maasai Mara (46873171904).jpg |
The southern ground hornbill (Bucorvus leadbeateri; formerly known as Bucorvus cafer), is one of two species of ground hornbill and is the largest species of hornbill. The other species of the genus Bucorvus is the Abyssinian ground hornbill, B. abyssinicus. The southern ground hornbill is characterized by black coloration and vivid red patches of bare skin on the face and throat (yellow in juvenile birds), which are generally 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 straight 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, but have a duller patch of grey in its place. Southern ground hornbills can be found from northern Namibia and Angola to northern South Africa and southern Zimbabwe to Burundi and Kenya. And Hawaii as they have escaped the Honolulu Zoo. They require a savanna habitat with large trees for nesting and dense but short grass for foraging. 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 are engaged in aerial pursuits. They forage on the ground, where they feed on reptiles, frogs, snails, insects and mammals up to the size of hares. Southern ground hornbills very rarely drink: their range is limited at its western end by the lack of trees in which to build nests. 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 territories, which must be as large as 100 square kilometres (40 sq mi) even in the best habitat. They are among the longest-lived of all birds, and the larger southern species is possibly the slowest-breeding (triennially) and longest-lived of all birds.
