Martin Walsh.

Dr. Martin Walsh is currently Research Methods Adviser in Oxfam GB. Formerly independent development consultant and researcher based (at different times) in Mombasa, Zanzibar, and Cambridge; Affiliated Lecturer in the Department of Social Anthropology, University of Cambridge; Social Anthropologist (Principal Scientist) in the Natural Resources Institute, University of Greenwich / Overseas Development Administration; Research Fellow in the School of African and Asian Studies, University of Sussex; undergraduate and Ph.D. student in the Department of Social Anthropology, University of Cambridge; and many other things in between. Dr. Walsh can also be found updating his own blog relating to East Africa here: www.notesandrecords.blogspot.com

He has kindly permitted Safaritalk to republish a series of articles produced by himself and Dr. Goldman, which can originally be found here www.zanzibarleopard.blogspot.com.


[text (with updated references) of an article originally published in 2003 in Nature East Africa, 33 (1/2): 14-16. An abridged version, 'The Zanzibar Leopard – Dead or Alive?', was published in 2004 in Tanzanian Affairs, 77: 20-23]



The Zanzibar Leopard, Panthera pardus adersi, is an elusive and possibly extinct subspecies endemic to Unguja (Zanzibar) Island. It has presumably been evolving in isolation from other leopards since at least the end of the last Ice Age, when Unguja was separated from the Tanzanian mainland by rising sea levels. The “founder effect” (genetic characteristics of the marooned population) and/or adaptation to local island conditions produced a smaller leopard than its continental relatives and one which “changed its spots”, or rather saw its more numerous rosettes partially disintegrate into spots (Pakenham, 1984; Kingdon, 1989).

Not much is known about the biology of the Zanzibar Leopard. Visitors to the natural history section of the Zanzibar Museum will be familiar with the stuffed and rather faded specimen kept in a display case there together with an old black and white photograph of a leopard trap. Apart from scraps of pelt furtively kept by hunters, to date we have only located five other skins: three in the Natural History Museum in London and two in the Harvard Museum of Comparative Zoology in Cambridge, Massachusetts. Of these only the type specimen in London and the two Harvard skins are accompanied by their skulls.


The Zanzibar Leopard’s behaviour is also poorly understood. It has never been studied in the wild and the last time a researcher claimed in print to have seen one was in the early 1980s. Rural Zanzibaris’ descriptions of the leopard and its habits are coloured by the widespread belief that an alarming number of these carnivores are kept by witches (wachawi) and sent by them to harm or otherwise harass their fellow villagers. This belief comes together with an elaborate package of ideas about how leopards are bred, trained, exchanged and sent to do the evil bidding of their owners. For local farmers this supplies a neat explanation for predation by leopards on livestock and humans, and more generally for their appearance “out of place” in the vicinity of farms and villages (Goldman and Walsh, 1997).



The growth of human population and agriculture in the 20th century was largely responsible for this state of affairs, as people encroached on the habitat of leopards and the animals they preyed upon. Increasing conflict with leopards and the fear that this generated led to a series of campaigns to exterminate them. These were localised at first, but became island-wide after the Zanzibar Revolution, when a combined anti-witchcraft and leopard-killing campaign was launched under the leadership of Unguja’s most famous witch-finder, Kitanzi. The long-term result of this campaign and the subsequent classification of leopards as “vermin” was to bring them to the brink of extinction (Walsh and Goldman, 2003).

The available evidence suggests that when we began our joint research on the Zanzibar Leopard in the mid-1990s there were still a few of these elusive animals remaining (Goldman and Walsh, 2002). Now we can’t be so sure. Most zoologists think that this island leopard is extinct: indeed some of them already thought so when we began our joint study in 1996. This pessimistic conclusion scotched subsequent proposals for a conservation initiative targeting the Zanzibar Leopard: if they were gone or going then there wasn’t much point in trying to do anything about it - apart from supporting the habitat conservation initiatives that were already underway on the island.

By contrast, the majority of people who live and work on the “coral rag” lands of southern and eastern of Unguja, including government staff and conservationists, believe that the Zanzibar Leopard has not been completely exterminated. Claims of sightings abound, as do reports of other evidence for leopards’ continued presence on the island and their nefarious use by witches. Many of these reports are difficult to evaluate and impossible to verify independently. So far none of the cases that we have investigated over the past two years (2002-03) has produced confirmation of a sighting or other leopard signs.



The recent scientific “discovery” of the Zanzibar Servaline Genet, Genetta servalina archeri, previously known only to islanders themselves, suggests that perhaps Unguja has yet to give up all of its zoological secrets. This small carnivore, another island endemic, was first described from an old skin and skull obtained in 1995. Its status was uncertain until a number of individuals were photo-trapped in January 2003 (Goldman and Winther-Hansen, 2003a; 2003b). If the Zanzibar Leopard survives, then similar standards of proof will have to be applied for any record to be acceptable to the scientific community. Otherwise most of us will get no closer to it than that faded museum specimen and those colourful cryptozoological narratives.


In addition to all of the people and institutions acknowledged in our original (1997) report, we would like to thank Daphne Hills in the Zoology Department (Mammal Group) of the Natural History Museum, London, and Judith Chupasko and Mark Omura in the Mammal Department, Harvard Museum of Comparative Zoology, for facilitating the examination and recording of specimens.

Did you see my request in a different post? Ask and receive!

This gave me a glimmer of hope that some may still exist, but even so, survival of the species seems dicey. The Zanizibar leopard lives on in the form of a postage stamp. Thanks for the blog links.

~ “Claims of sightings abound...”


Those few words stir hope, if only they might eventually be followed with tangible evidence.


Nonetheless, this was an interesting article.


Leopards on Zanzibar Island’ has a certain flair to it.


I enjoy finding this type of information archived in Safaritalk.

This article is a great read and actually highlights the issue where superstitions can actually run an animal into extinction.
