Welcome to the Mabula Ground Hornbill Project

We would like to ensure that this site contains all you need to know about Southern Ground-Hornbills (Bucorvus leadbeateri) and their conservation. This charismatic species is both culturally and ecologically important. They are hailed across their sub-Saharan range as the thunder birds or rain birds. They are also a valuable flagship species for the savannah biome as they are easily recognisable and have such large spatial requirements that any successful conservation action in even on territory benefits all the other savannah and grassland species, including threatened species such as vultures, wild dog and cheetah.

At present, Southern Ground-Hornbills are considered internationally as ‘Vulnerable’ throughout their range in Africa by the IUCN, but within South Africa and Namibia they have already been classified as EndangeredTaylor et al. 2016, with their numbers outside of formally protected areas are still declining. It is even likely that the birds will soon meet the IUCN Red Data List Criteria as being ‘Critically Endangered’ in South Africa. 

The reasons for their decline are predominantly loss of habitat to croplands, bush-encroachment, overgrazing and plantations, loss of nesting trees, secondary poisoning and electrocution. 

We are working to slow the decline by:

  • Harvesting and assisting the hand-rearing of redundant second-hatched chicks that would naturally die of starvation and dehydration if left in their wild nests. These artificially reared chicks then form the basis of bot the reintroduction and captive breeding programmes.
  • Re-wilding these artificially-reared chicks using wild-experienced adults as mentors in carefully managed groups called bush schools.
  • Reintroduction of the ‘rescued’ birds back into areas where they have become locally extinct once original threats in those areas have been mitigated.
  • Provision of artificial super nests to wild groups with no or inadequate nests.
  • Research on genetics, behaviour and other important unanswered questions necessary for successful conservation management of the species.
  • Coordination of a nationwide awareness campaign to educate the general public to the threats facing the thunder birds and to reinstate the bird into the collective memory in areas where it has become locally extinct.
  • Custodianship programme that aids land-owners and managers to manage in a way that will ensure the sustainability of their ground-hornbill families.

We have come a long way since 1999, when the first group of ground-hornbills was released at the Mabula Private Game Reserve in Limpopo, marking the establishment of the project. Partnerships have been formed, chicks have been rescued and reared, birds have been rehabilitated or re-wilded and released, awareness has been raised and people have rallied together, all in an effort to turn things around for ground-hornbills. We hope you too will join and support us to ensure that the THUNDER BIRD continues to roam the African savannahs and grassland.
