Southern Ground Hornbill Bucorvus leadbeateri
These big ones occur almost only in the Kruger Park, so what can one do, one must go Kruger despite the sometimes lost wilderness experience

Kruger National Park, 25 August 2014
During the 20th Century its range and population size Southern Ground Hornbills in South Africa decreased by some two thirds, with the birds disappearing from much of their historical range. Such a rapid decrease in the population of a long-lived, slow-breeding animal is of great conservation concern and, based on IUCN criteria, the official conservation status of Southern Ground-Hornbills in Southern Africa has been elevated from Vulnerable to Endangered.
Identification: Size very large; turkeylike; mostly black; in flight primaries white; red wattles distinctive; ♀ usually has purplish blue also on face, orbital skin and wattles. Iris yellow; skin of face, throat and wattles bright red, bluish on centre of throat in ♀; legs and feet black, soles whitish.
Immature: Browner than adult; facial and gular skin light khaki; bill dark grey.
Distribution: The Southern ground-hornbill occurs from Kenya and the DRC to southern Africa, where it is widespread but fairly scarce in Botswana, Zimbabwe, Mozambique, KwaZulu-Natal, Eastern Cape, Limpopo Province and northern Namibia.
Habitats: Any woodland, savanna, open grassveld, agricultural lands.
Habits: In pairs or groups of usually not more than 8 birds (2-4 adults and 1-3 immatures); mean group size (290) 3,6 birds. Neighbouring groups chase each other in aerial pursuits. Forages on ground, walking with stiff rolling gait on terminal phalanges of toes; digs with bill for food. Vocal mostly early morning; also late afternoon. Flight powerful with deep wingbeats, little gliding. Roosts in groups at ends of branches, head tucked into shoulders, bill pointing upwards.
Food: Entirely carnivorous; reptiles (including tortoises), frogs, snails, insects; also mammals up to size of hare.
Breeding: Monogamous, cooperative breeder, with a group consisting of a dominant breeding pair and sometimes helpers, who are either adult males or juveniles from previous breeding seasons. The group roosts in trees on rock faces, descending to the ground just before dawn and foraging for a lot of the day. They often take a break at midday to play, preen and pass around food to one another. The nest is usually a cavity in a tree lined with dry leaves, rarely nesting in cavities in rock faces or earthen banks. The same site is used repeatedly over many breeding seasons. Egg-laying season begins with the first heavy summer rains, from August-January, peaking from October-November. It lays 1-2, rarely 3 eggs 3-14 days apart, which are incubated solely by the female for 37-43 days. The female only makes 3-4 brief sorties out of the nest per day, so is largely reliant on the male and helpers to provide food. The eggs hatch in the sequence laid, meaning that the one chick is 3-14 days older than the other chick. The younger chick is unable to compete for food with its older sibling, and dies of starvation when it is about one week old, occasionally surviving for a few more weeks.. The female leaves the nest when the chick is about four weeks old, after which the chick is mostly alone in the nest. The fledging leaves the nest when it is approximately 86 days old, remaining with its parents for several years.
