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.
My copy of John Preston's book Touching The Moon (© John Preston/Mandarin Paperbacks – reproduced here on a strictly non-commercial Fair Use basis for educational/review purposes only)
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!
