Ruwenzori (aka Rwenzori and Rwenjura) constitutes an East African mountain range at the border of the Democratic Republic of the Congo (formerly Zaire) and Uganda. Below their peaks' snowy caps and alpine meadows, these mountains are covered in lush tropical rainforests and are rightly deemed to be a biodiversity hotspot, with many regions still only sparsely explored scientifically. Not surprisingly, therefore, some interesting potential cryptids have been reported from Ruwenzori, including the three examples presented here.
GOING POTTY ABOUT A GIANT POTTO
Some of cryptozoology's least-known mystery beasts have often long been hiding in plain sight, at least in the sense that they have been documented in books or articles originally published many years ago but which have never attracted cryptozoological attention. Consequently, whenever possible I try to rectify this sad situation by publicising these cryptic cryptids once I've learnt about them.
So here is yet another example, kindly brought to my attention on Facebook by longstanding FB friend Richard Hing on 16 August 2023.
In his FB post, Richard wondered if anyone had ever heard of a strange creature reportedly existing in Ruwenzori and briefly referred to by BBC wildlife film-maker/author Michael Bright in a BBC Wildlife Magazine article from November 1987 concerning the fauna of these infamously impenetrable, inaccessible mountains.
Michael had been writing about how fascinated by the Ruwenzoris and their natural history was Pelham Aldrich-Blake, producer of the renowned TV series The Natural World and a longstanding lover of mountain-climbing, and while listing the various creatures existing here Michael included the following short but very tantalising paragraph:
Pelham also mentions the occasional solitary leopard and a creature that most people consider more mythical than fact – the 1.5m [5-ft]-long giant Ruwenzori potto, which shares the scientific twilight with Nessie and the yeti. It is described in the [local native] stories as simply a huge version of the well-known big-eyed primate and is supposed to glower at intruders from the branches of 10m-tall giant heathers.
Pottos are related to and somewhat resemble the more familiar lorises of Asia, especially the slow lorises. For many years, only a single geographically-widespread potto species, Perodicticus potto, was recognised, inhabiting West Africa, Central Africa, and East Africa, but in more recent times this species has been divided taxonomically into three separate ones, based on genetic analyses published in 2015 indicating that they split from one another in evolutionary terms as long ago as the Miocene Epoch (23-5.3 million years ago).
These are now, respectively, the common or West African potto P. potto, the Central African potto P. edwarsi, and the East African potto P. ibeanus. (There is also the mysterious false potto Pseudopotto martini, represented only by skeletal remains from two specimens of uncertain provenance and unknown external appearance, but which may merely be aberrant specimens of P. potto.)
Nevertheless, they are all still united by one very noticeable shared feature – none of them exceeds around 50 cm [20 in] (including its short tail) in total length, i.e. only a third the alleged length of the aptly-dubbed giant Ruwenzori potto. Consequently, assuming that the latter really does exist, and really is 1.5 m (i.e. 150 cm) [5 ft] long, it seems reasonable to speculate that this exceptionally large variation on the potto theme does indeed represent a taxonomically discrete form still awaiting scientific recognition and naming. Incidentally, if anyone has additional information concerning it, I would love to receive details!
Nor is this giant potto the only obscure cryptozoological curiosity on record from the Ruwenzoris.
THE MOON BIRDS OF RUWENZORI
Two totally separate reports of very large but
still-unidentified black birds have also been chronicled from these lofty peaks.
The Ruwenzoris are popularly and poetically dubbed the Mountains of the Moon, because they were traditionally deemed to be the real-life identity of the mysterious legendary mountains given this romantic name by ancient Greek and Roman geographers who believed that they comprised the long-hidden source of the River Nile.
The first 'moon bird' report, documented by John Preston in his 1990 Ruwenzoris travelogue Touching The Moon, is that of that of the local guide accompanying explorer Stephen Bagge during his Ruwenzori ascent in 1898.
Bagge reached an altitude of 9,000 ft, but his guide climbed a little higher, alone, reaching Lake Bujuku, south of Mount Speke. According to this guide, he saw on its shores a number of all-black birds as large as sheep, which uttered an alarm call resembling the bellow of a bull when he tried to approach them, which scared him away. In 1906, conversely, a very extensive Ruwenzoris expedition led by Italian explorer the Duke of Abruzzi did not report encountering any such birds there.
However, in his 1957 book Animal Africa, Canadian mountaineer Earl Denman recalled that while climbing the Ruwenzoris a few years earlier, he had watched a couple of very large unidentifiable black birds diving swiftly and almost vertically through the high mountain air. Were these of the same mystery species as those that Bagge's guide had seen, or something different again?
Cryptozoological author George Eberhart has speculated that Denman's birds may have been a pair of Verreaux's eagles Aquila verreauxii – a striking species that is indeed native to the highlands of East Africa, has predominantly black plumage, a very impressive wingspan of up to 8 ft, and an extremely dramatic aerial courtship display that features spectacular vertical dives.
Consequently, I think this a plausible identity for Denman's birds, but Bagge's remain far more mystifying.
After all, it seems unlikely that a number of eagles would all congregate together around the shores of a lake, and utter a bull-like sound when approached. To me, such behaviour is much more indicative of birds such as cranes, herons, storks, or even bustards, but I'm not aware of any known species that corresponds both morphologically and zoogeographically with Bagge's birds.
And so, over a century later, these remain as enigmatic now as they were back in 1896. Once again, any additional info would be very welcome!
Fascinating article - never heard of this remote and poorly studied ecosystem before now, let lone all the mysterious animals reported from it as of yet unattested to by mainstream science. Many thanks for posting this Karl!
