MEET THE MONSTROUS MAKALALA - A TANZANIAN TERROR BIRD?

Reconstruction of the makalala's possible appearance in life (© Markus Bühler)

Here's something suitable for Hallowe'en from the cryptozoological chronicles – a monster bird with a taste for flesh...human flesh.

No one doubts that the tallest species of bird alive today is Struthio camelus, the ostrich - no-one, that is, except for the Wasequa people (most probably an alternative, kiSwahili name for the Zigua - see Pat the Plant's very informative comments posted at the end of this ShukerNature blog article - thanks Pat!), who inhabit an unspecified interior region of mainland Tanzania 8-9 days' journey from the coast of Zanzibar (the Zigua do live directly inland from Zanzibar).

According to a report by a Count Marschall (Bulletin de la Société Philomatique, 1878-9), as recently as the 1870s these people averred that their territory harboured a monstrous bird even taller than the 8-ft-high ostrich, equipped with very long legs, the head and beak of a bird of prey (which it puts to good use when feeding on carrion from animal carcases), and the ability to take to the air in sustained, powerful flight. Also, each of its wingtips bears hard plates composed of a horny, compact substance, and when it strikes its wings together they produce a very loud noise, earning this bird its local name - makalala ('noisy').

Marschall claimed that the makalala is said by the Wasequas to be very fierce, but can be killed if the correct strategy is employed. Engaging upon an extremely hazardous version of 'playing possum', the would-be assassin has to lie on the ground and feign death, until the makalala approaches close enough to seize the supposed human carcase - whereupon the latter must reanimate himself instantly and deliver the fatal blow before the makalala can rectify its mistake!

So far, this could all be discounted as fanciful native folklore - but physical remains of the makalala may have been recorded too. Marschall mentioned a Dr Fischer, who saw in Zanzibar an object that he identified unhesitatingly as a rib from some form of gigantic bird. Narrowing from one end to the other, this alleged rib had a width of 8 in at its widest end, and was just under 1 in at its narrowest end. Unfortunately, Marschall did not record whether Fischer sent it to a scientific institution for conclusive identification and retention.

However, Marschall did record another possible source of makalala remains - because he noted that native chiefs placed makalala skulls on their heads, using them as helmets! Could any of these bizarre examples of protective headgear still be owned today by Wasequa tribesmen?

Thanks to my afore-mentioned correspondent Pat, I now have a copy of a second makalala document from the same time period - namely, the published account by the Dr Fischer alluded to by Marschall in his own report. He was Dr Gustav A. Fischer, and his account of the makalala was part of a much longer report co-authored in German with Dr A. Reichenow, which was published in 1878 within the Journal für Ornithologie. Interestingly, in his own account Fischer described the makalala as being very shy (rather than very fierce as claimed for him by Marschall in his report), and stated that he was reluctant to believe that the rib-like structure came from a bird (whereas Marschall claimed that Fischer readily identified it as such), but otherwise the two descriptions correspond well with one another.

Assuming, against all the odds, that the makalala is real - that the frightening scenario of a carnivorous bird taller than the ostrich surviving into historical times somewhere in mainland Tanzania's interior is not a grotesque fantasy but a sober fact - what could it be? Several interesting, albeit mutually-exclusive lines of speculation compete for attention.

The first of these to be discussed here was kindly brought to my attention by German cryptozoologist Markus Bühler. Breeding throughout much of sub-Saharan Africa, sporting an immense wingspan of up to 10.5 ft (even greater spans have been claimed but presently not verified), standing up to 5 ft tall, and weighing as much as 20 lb, the well known marabou stork Leptoptilos crumenifer (syn. crumeniferus) is certainly an extremely impressive, potentially formidable bird. Indeed, when specimens are scavenging from a carcase, they will sometimes even ward off vultures once the latter birds of prey have torn chunks of flesh from the carcase with their hooked beaks (which marabous lack). Even so, it seems unlikely that such a familiar species could have somehow been converted by local myth and superstition into a mystery bird.

However, as Markus pointed out, during the Pliocene, Africa was also home to an even bigger species of marabou stork, L. falconeri, Falconer's marabou. Like L. crumenifer, it was widespread across northern and eastern Africa but stood around 6.5 ft tall (taller than an adult human of average height) and weighed up to 44 lb (as heavy as a small child). In comparison to L. crumenifer, Falconer's marabou exhibited a slight reduction in wing size, therefore possibly being more terrestrial than its modern-day relative, but it was still fully able to fly. As birds often look much bigger than they actually are, due to their plumage and pneumatic internal system adding substantial volume to their forms, this already-huge species would have been truly monstrous in appearance, added to which its possibly greater terrestrial lifestyle means that it may possibly have been able to kill and eat bigger creatures than L. crumenifer.

Based upon fossil evidence, Falconer's marabou stork had become extinct by the end of the Pliocene 2.5 million years ago, but if it had somehow survived into historical times (with what would be its more recent fossils not having been uncovered so far), there is no doubt that it could have been a thought-provoking makalala candidate (albeit one lacking the raptorial beak claimed by the Wasequas for the makalala). Even the latter's supposed wing-clapping sounds might in reality have been a confused memory of the beak-clapping sounds often produced by storks, and which would have been very loud if made by Falconer's marabou. However, there is currently no scientific evidence that the latter species did survive into historical times.

Another very large and intriguing species of bird that once inhabited Africa is Eremopezus eocaenus, which, as its name indicates, lived during the Eocene (specifically the late Eocene, between 36 and 33 million years ago). Its fossil remains, which have been obtained from Jebel Qatrani Formation deposits around the Qasr el Sagha escarpment, north of the Birket Qarun lake near Faiyum in Egypt, indicate that this was a very large, flightless, and quite possibly predatory bird, probably as tall as a small emu or large rhea but bulkier in form. Its taxonomic position has incited much debate, and it has yet to be confidently allied with any existing avian lineage, but the enigmatic Eremopezus does possess certain interesting and quite specific anatomical similarities with the secretary bird – a highly distinctive African species that will feature a little later in this discussion of potential makalala identities.

Could Eremopezus itself, however, be linked to the latter mystery bird? It seems implausible that this species could have lingered on into the present day or given rise to modern-day descendants without some geographically intervening remains have been found somewhere between Egypt and Tanzania's portion of East Africa. Then again, the fossil record is famously incomplete.

With flagrant disregard for zoogeographical dictates, the makalala readily recalls the phorusrhacids or terror birds. These were an aptly-named taxonomic group of huge flesh-eating birds known predominantly (but not exclusively) from the New World, and which attained their awesome zenith with a truly gigantic, spectacular species from Argentina's Patagonia region called Kelenken guillermoi.

Sporting a massive 28-inch-skull armed with an enormous hooked beak, this 10-12-ft-tall horror died out approximately 15 million years ago during the mid-Miocene, whereas Titanis walleri (originally thought to have been 10-12 ft tall too until further finds led it to be downsized to a still-daunting 5-6 ft) not only reached North America but lived there in Texas and Florida until as least as recently as 2.5 million years ago, making it the youngest terror bird species currently known. However, these fearful birds were flightless, as their wings were vestigial. Moreover, although confirmed terror bird fossils have been discovered in the Americas and also Antarctica, the only known fossil evidence for their erstwhile existence in Africa is a single femur from an individual that had lived during the early or early-to-mid-Eocene (i.e. between 52 million years and 46 million years ago) in what is today southwestern Algeria. In 2011, this mysterious species was named Lavocatavis africana.

Even so, could the makalala be an undiscovered modern-day species? There is one notable precedent for such speculation, because some zoologists consider it plausible that a living, flying species of phorusrhacid-related bird is already known from Africa – namely, that strange, stork-like bird of prey called the secretary bird Sagittarius serpentarius. Although it is commonly classed as an aberrant accipitrid based upon molecular analyses, egg albumen comparisons have suggested in the past a closer taxonomic allegiance between this species and a pair of South American birds known as seriemas - which constitute the last surviving members of a phorusrhacid-allied taxonomic family.

In any event, the secretary bird affords a compelling correspondence to the makalala's morphology (albeit on a rather more modest scale). Standing up to 4.5 ft tall on notably long, crane-like legs, and endowed with strong wings that support a powerful, soaring flight, plus the head and hooked beak of a bird of prey, the secretary bird constitutes a very acceptable makalala in miniature. Furthermore, when attacking snakes (an important part of its diet) it frequently shields itself from potentially fatal strikes with its outstretched wings, which are equipped with horny tips - i.e. claws on the tips of its 'finger bones' (phalanges), instantly recalling those of the makalala.

This last-mentioned correspondence is particularly telling, because there are very few species of bird alive today that are equipped with these wingtip claws. Indeed, other than the secretary bird, the only ones presently known are the three species of crane-allied birds called finfoots or sun-grebes, plus three vaguely grouse-like relative of waterfowl known as screamers, native to South America, and including the black-necked screamer Chauna chavaria, the cross-sectional shape of whose wing spurs is such that they are particularly noisy when clapped together. In addition, a strange pheasant-like bird known as the hoatzin Opisthocomus hoazin, again from South America, produces curiously reptile-like offspring able to crawl along tree branches by virtue of two large, mobile claws on each wing, but these are lost as the chicks mature. Over the years, the hoatzin has been classified with numerous different avian groups, including the galliforms, cuckoos, touracos, mousebirds, waders, sand-grouses, and many others, but it is currently deemed to represent the oldest living avian lineage, discrete from all others alive today.

Certain other birds, like the jacanas or lily-trotters, the spur-winged goose Plectropterus gambensis, the spur-winged plover Vanellus spinosus, and a pair of Antarctic endemics called sheathbills, possess horny spurs on their wings, used in combat - but these are variously sited on the 'wrist bones' (carpals) or 'hand bones' (metacarpals), not upon the finger tips.

Out of all of these species, moreover, only one - the secretary bird - is predominantly carnivorous. Could the makalala, therefore, be some form of extra-large secretary bird - not necessarily as tall as the Wasequas state (their fear of it could certainly have inflated their estimate of its height), but much bigger than today's single known species? If so, a suitable scientific name for it, based upon its morphological description given above, would be Megasagittarius clamosus - 'the noisy, giant secretary bird'.

Staying with the secretary bird line of speculation, is it conceivable, alternatively, that the makalala was a false secretary bird, i.e. some other raptorial species, possibly another accipitrid (the eagles, hawks, and Old World vultures), that had assumed via convergent evolution a form outwardly comparable to Sagittarius? Although this is just another suggestion with no tangible evidence to support it directly, there is actually an interesting confirmed precedent for such an ostensibly unlikely premise.

In 1989, Drs Alan Feduccia and Michael R. Voorhies formally described a remarkable new species of North American fossil accipitrid from the late Miocene whose tarsometatarsal structure was nearly identical morphologically to that of the secretary bird. Indeed, the convergence was so striking that they christened this species Apatosagittarius terrenus, which translates as 'terrestrial false secretary bird', because they considered it likely that just like the true secretary bird, it had exhibited a predominantly terrestrial hunting lifestyle. In fact, it was only because the tarsometatarsus bore some attached phalanges whose structure was very different from those of the secretary bird that Feduccia and Voorhies were able to confirm that Apatosagittarius was not a true secretary bird, but was merely an anatomical impersonator.

Finally, a sizeable bird native to western Tanzania but possibly venturing eastward occasionally into the region supposedly inhabited by the makalala is the shoebill Balaeniceps rex. Once deemed to be an aberrant stork but nowadays considered to be more closely related to pelicans, this highly distinctive species stands up to 5 ft tall, sports a very impressive 8.5-ft wingspan, is famed for its enormous hooked beak, and has such a positively prehistoric appearance when seen in flight that it has been proposed by some zoologists as the identity of supposed living pterosaurs spasmodically reported from various regions of East and Central Africa - click here for a ShukerNature blog article on this subject.

However, the shoebill's wings do not possess horny tips, so it could not make the loud wing-claps characterising the makalala. In addition, being principally piscivorous it doesn't scavenge carcases, it is shy of humans, and as its overall appearance is so singular that it seems unlikely the Wasequa would confuse such an unmistakeable species with anything else or convert it into a much larger, quite different mystery bird, this would seem to rule out the shoebill from further consideration concerning the makalala - unless, of course, there is a still-undiscovered species of giant shoebill out there...?

All of the lines of speculation discussed above – with identity contenders ranging from marabou storks, shoebills, and terror birds to secretary birds, false secretary birds, and even the anomalous Eremopezus – are certainly absorbing and thought-provoking, but even if any of them is valid, it is scarcely likely to yield a living makalala, sadly. After all, a bird as large and as visually distinctive as this one would surely be hard-pressed indeed to remain undiscovered by science for long, regardless of the geographical locality involved - yet there do not appear to be any post-19^th-Century reports of its existence.

Consequently, even if the makalala was a reality in the 1870s, presumably it no longer survives - but that does not mean that its former existence cannot be verified. As noted earlier, among the valued possessions and relics of present-day Wasequas there may still be one or more of the revered helmets worn by long-departed chiefs. Should one of these tribal heirlooms pass into the hands of an ornithologist, the lucky recipient could well find himself holding a bona fide makalala skull!

CRYPTO-SELFIES! IN THE PICTURE WITH SOME SERIOUSLY WEIRD – BUT WONDERFUL – WILDLIFE

With E.T. – how could I not take pity on this errant extraterrestrial and bring him back home with me? In any case, he must be happy here – he hasn't phoned home once, which is just as well, bearing in mind the cost of intergalactic telephone calls these days! (© Dr Karl Shuker)

Over the years, I've found myself sharing space in photographs – selfies, as they'd be called nowadays – with some exceedingly strange entities (and those are just my friends!). But seriously, browsing through my albums recently I came upon a considerable number featuring me alongside some truly weird – but indisputably wonderful – wildlife. So here, as one of my more light-hearted ShukerNature contributions, and the first of an occasional series, is a dozen of my most memorable crypto-selfies, annotated with a bountiful abundance of decidedly (ir)relevant information…

Alongside a black cheetah statue at Colchester Zoo, in Essex, England, which I visited in 2013; as noted in my books Mystery Cats of the World and Cats of Magic, Mythology, and Mystery, a few records of all-black (melanistic) cheetahs are indeed on file, including a specimen spied in the company of a normal cheetah by Lesley D.E.F. Vesey-Fitzgerald in Zambia during the first half of the 20^th Century, and another one sighted in Kenya's Trans-Nzoia District by H.F. Stoneham in 1925 (© Dr Karl Shuker)

With one of the famous 19^th-Century dinosaur statues at Crystal Palace Park in Bromley, London, which I visited in 2009; created by famous sculptor Benjamin Waterhouse Hawkins (1807-1894) and totally outdated now, this one is meant to be a Megalosaurus, but its reconstruction was guided by the popular yet erroneous belief current at that time that dinosaurs resembled giant lizards (© Dr Karl Shuker)

At Drayton Manor Park and Zoo, in Staffordshire, England, standing somewhat warily alongside a disconcertingly life-like, life-sized replica of North America's late Pliocene/early Pleistocene terror bird Titanis walleri, which may have stood up to 8 ft tall – check out my book The Menagerie of Marvels for an extensive chapter documenting the history of these flightless but fleet-footed and sometimes truly gargantuan carnivorous birds (© Dr Karl Shuker)

With an acklay – when I purchased this model at a market a few years ago, I had no idea what the creature was that it represented, but thanks to some knowledgeable sci-fi enthusiast friends on Facebook I soon learnt that it was an acklay, a huge non-sentient carnivore up to 11.5 ft tall, hailing from the planet Vendaxa in the Star Wars canon's universe (© Dr Karl Shuker)

Alongside a life-sized animatronic model of the feathered dinosaur Citipati at Bristol Zoo, England, in 2013; an oviraptorid theropod from Mongolia's Late Cretaceous period, Citipati was named after a pair of murdered meditating monks from Tibetan Buddhist folklore, it possessed a large toothless beak, and it stood as large as a present-day emu; in this particular reconstruction, it looks decidedly cassowary-like (© Dr Karl Shuker)

There I was, minding my own business walking round the small West Midlands, England, town of Cradley Heath, when, happening to step inside a sci-fi/comic shop, who should I encounter there but the Predator! I can only assume that my trusty leather biker jacket helped to conceal me from its thermal imaging capability long enough for me to get this photo snapped of me alongside it; if you're wondering why the photo is a little blurry, it's because the (ex) person taking it for me suddenly realised that unlike me he wasn't wearing anything to cloak his thermal image – I won't tell you what happened to him next, as I don't want to give you nightmares – suffice it to say that at least it kept the Predator occupied long enough for me to make my excuses and exit stage right! (© Dr Karl Shuker)

Face to face with a life-sized Tyrannosaurus rex model at a dedicated T. rex exhibition held at Birmingham Museum & Art Gallery in the West Midlands, England, during 2010 – it's not often that you get the chance to stare down a T. rex, although in this particular instance the only thing that I seemed to be staring down was its nostrils; Jurassic Park claimed that as long as you stood perfectly still, a T. rex would be unable to detect you, so what better time to put this claim to the test?? © Dr Karl Shuker)

Sharing some quality time with a life-sized Moeritherium statue at London's Natural History Museum in 2014; this was a very early genus of proboscidean living during the Eocene epoch 37-35 million years ago in northern and western Africa, but dying out without giving rise to any modern-day elephant lineage; initially I was very puzzled that this statue's trunk seemed to have been rubbed so vigorously that much of its surface had lost its colour – why would this have happened? Then Facebook friend Adam Naworal reminded me that it was traditional to rub elephant statues for good luck, so that may well explain the otherwise anomalous case of the mutilated Moeritherium; fortunately, however, this doesn't seem to have traumatised him, as he seemed happy enough to be with me (© Dr Karl Shuker)

Alongside Singapore's iconic merlion fountain-statue in 2005; the merlion is a legendary lion-headed fish known worldwide as a symbol of Singapore, and it is epitomised by this magnificent 28-ft-tall statue created by sculptor Lim Nang Seng during 1971-1972, and relocated in 2002 to a promontory in Singapore's Merlion Park (© Dr Karl Shuker)
