The Bornean Tiger; Speculation on its Existence
by Erik Meijaard*
This short note presents and discusses references to the occurrence of the tiger
Panthera tigris (Linn.) on the island of Borneo.
The numbers in the text refer to Figure 1.
There is no scientific evidence to support the theory that tigers occur naturally on Borneo
(Medway 1977). However, tiger skins (Hose and McDougall 1912, Sellato 1995), skulls
(Nieuwenhuis 1904, Banks 1931), and canine teeth (Peranio 1960, Puri 1992 pers. obs.)
have been observed in the possession of indigenous communities of the Sarawak interior
and in West and East Kalimantan. Medway (1977) believed that these items had been
imported.
Hooijer (1963) states that the recovery of the tip of an unerupted upper tiger canine from
a superficial level in the excavation at the Niah cave in Sarawak (no. 1) suggests that the
tiger may have been, until comparatively recently, a member of the native fauna.
Unfortunately, Hooijer does not go into detail of how he identified this find. Remains
from deeper levels in the cave had not been found in 1977 to corroborate the case
(Medway 1977), and I am not aware of any finds since then.
One skull apparently existed in the Natural History Museum in London earlier this
century and was labelled as "Borneo" (see Note). However, this skull may have been
mislabelled. Furthermore, there is documentary evidence of tiger parts being introduced
to Borneo by man. Nieuwenhuis, a Dutch anthropologist, brought tiger skulls and teeth
from Java to Borneo as presents for tribal leaders of the upper Mahakam and Kapuas
rivers in East and West Kalimantan respectively (Nieuwenhuis 1904).
Several authors mention evidence that the peoples of Borneo are at least very well aware
of the tiger. In his study area in interior East Kalimantan (no. 2), Puri (1992) noted that
tiger parts play an important role for the Penan and Kenyah people. Tiger teeth were used
by community leaders for lie detecting and were considered to be very powerful. Only
after 10 months did Puri get to see a set of six of them. Nieuwenhuis (1904) pointed out
the great importance of tigers in traditional Bornean arts and religion; so much was the
tiger worshipped and/or feared that it would generally be referred to only by a lesser
name, ‘aso or ‘dog’.
Sellato (1995) in his zoo-linguistical study reports that most Dayak languages have a
specific term to refer to the tiger that is quite distinct from other cats, such as the clouded
leopard (Neofelis nebulosa). Also the Aoheng, a Bornean tribe of the upper Sungai
Mahakam (Sungai = River, hereafter abbreviated as ‘S’) (no. 3), are aware of a number of
details pertaining to the tiger’s habitat and habits. This suggests that the tiger may have
occurred on Borneo in the past, or that the people who populated Borneo came from a
region of South East Asia where tigers existed (Sellato 1983, 1995).
Abbott (in Lyon 1911), a respected zoologist, actually believed that tigers existed in his
study area in west Borneo (no. 4). Based on local narratives he thought that a much larger
cat than the clouded leopard occurred. He thought it to be very rare, as few whom he met
had ever seen it. Also Witkamp (1932) refers to tigers, which were claimed to occur in
the ‘Tjina-batangan’ area (no. 5) in northern Borneo in the Natuurkundig Tijdschrift voor
Nederlands Indië of 1857. Finally, Gersi (1975) produced evidence of tigers on Borneo.
He claimed not only to have seen a tiger near the S. Belayan (no. 6) in East Kalimantan,
but he also took photographs of the animal. The two photos in his book clearly depict
tigers. His explanation for this sighting was that in the past the sultans of Sarawak, Sabah,
or Brunei must have imported these tigers from elsewhere. This explanation was
considered scarcely plausible by Medway (1977), who thought that this report (if
authentic) could only be evidence of a surviving indigenous publication. In his book,
Gersi (1975) further states that the nomadic Punan people of Borneo knew of a large,
striped cat species that, unlike the clouded leopard, did not climb trees.
During four years of fieldwork in many locations on Borneo I have come across a
considerable number of alleged tiger sightings. The most recent tiger report came from
the area between S. Pari and S. Hanyu in Central Kalimantan (no. 7), where a tiger was
said to have been heard in 1995, although no one managed to see it. The interviewees
asserted that they knew the roaring of the tiger well enough to discern it from other
animals. One Punan hunter told me he had had a clear tiger sighting on a logging road
near the S. Belayan in East Kalimantan (no. 8) in the early 1990s. Another informant said
he had seen a captive young tiger in a logging concession, near Bengalon in East
Kalimantan (no. 9). This animal was described as being different from both the Sumatran
tiger and the clouded leopard, by being largely brown-coloured with only faint stripes.
In the Central Kalimantan village of Tangiran (no. 10), old people told of a large striped
cat different from the clouded leopard. One tooth was shown; it was said to be between
one and two centuries old and once belonged to a tiger that lived in the vicinity of the
village. Finally, one sighting was reported from the PT Domas Raya logging concession
and dated back to 1987/88 (no. 11). Again it was said that the animal was faintly striped,
and the size of a Sumatran tiger.
Apart from the above useful records, the interviewee in the PT Domas Raya logging
concession told a more fanciful story. He stated that the local tiger lived in a cave and
would only come out in the seventh month of the year. It was thought to be associated
with hermits and ascetics who could take on the shape of this animal. The animal was
said to only occur in the mountains and not in lowlands like the Sumatran tiger. A.H.
Everett recorded similar traditions in which tigers were associated with caves (Banks
1931). These stories were centred on the Pupok Hill (no. 12), Serambo (no. 13), and
Bukit Rimong (no. 14), and mostly concerned a flying variety of the tiger that made
weird noises in caves at certain seasons of the year (Banks,1931).
Discussion
It is impossible to judge the significance of the reported tiger sightings. Mjöberg (1930)
already wondered about the apparent absence of tigers on Borneo, and it is indeed a
mystery why the tiger appears absent from the island. The species occurs in a variety of
habitats and seems to be very adaptable to different ecological conditions. On Borneo,
prey species, such as sambar Cervus unicolor, bearded pigs Sus barbatus, or muntjaks
Muntiacus spp. are common (pers. obs.), and, at present, there does not seem to be an
ecological factor on Borneo preventing the tiger’s survival.
I hereby postulate four theories that could provide explanations for the tiger’s absence
from, or the presence on, Borneo:
1. Tigers never occurred on Borneo
The island of Borneo has been connected to Sumatra and Java several times during the
Pleistocene when lower sea levels exposed the Sunda shelf. It is generally assumed that
during the glacials most faunal exchanges between the islands occurred (e.g. Groves
1990). Tigers swim well and could certainly have crossed the rivers that dissected the
exposed Sunda shelf. However, the drier climate during the glacials probably created
open woodland savannah conditions on the shelf (for a discussion on this subject refer to
Adams and Faure, 1997). It is therefore possible that the tiger, with a need for dense
vegetation cover, and access to water (Sunquist and Sunquist 1989), found the exposed
Sunda shelf too much of a barrier. Brongersma (1935) proposed an alternative
explanation. He suggested that the tiger reached the archipelago at a time when Sumatra
and Java were still connected, but already separated from Borneo (in the late Pleistocene).
2. Tigers once occurred naturally on Borneo but became extinct
Because of ecological conditions during the glacials, few tigers could reach Borneo.
Furthermore, the carrying capacity of forest on Borneo’s weathered substrate
(MacKinnon et al. 1996) is generally less than on the rich volcanic soils of Java and
Sumatra. Animal densities are therefore lower in Borneo, potentially supporting lower
tiger densities (e.g. Rijksen and Meijaard 1999). It could thus be relatively easier to hunt
a species to extinction in Borneo than in other areas, especially if most of the indigenous
population hunted wildlife. Also, the great cultural importance of tigers in Borneo could
suggest that the species would once have been heavily pursued by human hunters.
3. Tigers still occur naturally on Borneo
A very small possibility, but one that cannot be entirely ruled out. As opposed to the
theory above, one could reason that a tiger population that occurs naturally at low
densities, as it did in Borneo, might be better able to cope with dispersed individuals than
a naturally high-density population at artificially low densities. Also hunting pressure on
very dispersed animals may be low because the effort required to find a tiger would
outweigh the potential profit. Therefore, a very low-density population in Borneo may
have had a better chance to survive than elsewhere.
4. Tigers were once introduced to Borneo and established a wild-living population,
which either survived or died out
As far as I am aware there is no historic documentation of tigers being introduced to
Borneo, and I appeal to readers for any information on this.
Conclusion
Proving that a species is present is relatively straightforward, but finding proof that it has
become extinct or locally absent is very difficult. At least a few times per year Indonesian
newspapers still report on new observations of the now thought to be extinct Javan tiger
(P. t. sondaica) in one of the most densely populated areas of the world. Luckily for the
tiger there is no known historical presence on Borneo. I say ‘luckily’, because, ironically,
if we assume that there is a remote chance of tigers surviving on Borneo, it may be the
least threatened population of all, as few would be specifically pursuing them for their
prized parts.
The question of what to do with the above tiger reports remains. If the scientific world is
interested in finding out more, systematic interviews with indigenous hunters combined
with camera trapping may be the best way to test whether tigers still occur. Camera
trapping would be very useful because it would not only target tigers but also come up
with information on a whole range of other little known Bornean species. Clearly positive
results from camera trapping would still not tell whether tigers occur naturally or were
introduced. Because two reports of tigers refer to a brown, faintly striped animal, it would
be useful to ask informants how the Bornean tiger compares to the Sumatran tiger.
Finally, an alternative approach, of course, would be to leave the image of the Bornean
tiger intact in the mists of mythology.

Note: Several authors have referred to a "Bornean" tiger skull at the Natural History Museum (NHM) in
London. Gray (1862, 1867, 1874 in Brongersma 1935) probably first mentioned the Bornean skull. Pocock
(1929) reports on the record of an old skull, labelled "Borneo", in the British Museum. Medway (1977: p.
146) mentions a tiger skull registered at the BMNH in 1859 as ‘Purchased’, with the locality "Borneo".
Medway quotes the documentation as saying: "...This skull, attributed to Wallace on the label, is one of a
small group of accessions simultaneously registered at the BMNH in 1859 as ‘Purchased’, with the locality
"Borneo". Among other items in the group are a skull of Rhinoceros sondaicus (q.v. above), two skulls and
some teeth of Babirussa and the skull of a tiger. There have been no subsequent authenticated records of
any of the mammals, nor of Sus verrucosus, in Borneo, and the locality is evidently erroneous". A.
Kitchener (in litt. 6 May 1999) referring to Medway (1964) mentions a Bornean tiger skull from the
Warwick collection, while C. Smeenk (Curator Mammal Collection Leiden Museum, in litt. 8 June 1995),
referring to Gray’s catalogue of 1862, stated that the skull was in the Wright collection at the NHM.
Interestingly, D. Hills of the NHM’s mammal section, reports that there are no tiger skulls from Borneo and
to her best knowledge none marked "Borneo" in the collection (D. Hills, in litt. 6 May 1999). This example
shows the difficulty of delving into the history of such matters.
... It is found in most middle and late Pleistocene sites in SE Asia, including Tam Hang, Punung, Niah Caves, Kecil, and Hang Hum (Fig. 2). Tiger populations are today present though in severely reduced numbers in Sumatra, and India, and possibly China, and tigers were present in Java, Bali (Kitchener and Dugmore, 2000) and probably Borneo (Meijaard, 1999; Piper et al., 2007) until historical times. ...
... While tigers are still extant, they have been reported from Pleistocene sites throughout Southeast Asia, including Java, Borneo and the Philippines, where they are now extinct. These extinctions are recent e tigers have been recorded from historical records in both Java and Bali (Kitchener and Dugmore, 2000) and possibly the ethnological records of Borneo (Meijaard, 1999; Piper et al., 2007). Tigers show a dramatic decline in geographic range in Southeast Asia over the Holocene, similar to that experienced by extinct megafauna (Louys, 2012b). ...
... A rapid assessment method that produces reliable information on the conservation status of these species would be very useful. In Borneo, secondary information has been used for various research purposes such as understanding a species distribution and population trends (e.g., clouded leopard [Neofelis nebulosa; Rabinowitz et al., 1987]; Sumatran rhinoceros [Meijaard, 1996]; bay cat [Catopuma badia; Meijaard, 1997]; tiger [Panthera tigris; Meijaard, 1999]; ethno-zoology [Mohd-Azlan & Faisal, 2006]; bay cat [MohdAzlan & Sanderson, 2007]; wildlife inventory [Mohd-Azlan, 2004]; fl at-headed cat [Prionailurus planiceps; Wilting et al., 2010]; orangutan [Pongo pygmaeus; Meijaard et al., 2011]; fl ying fox [Pteropus vampyrus; Harrison et al., 2011]). In all these, surveyors did not record the species directly (e.g., sighting, camera-trapping) or indirectly (e.g., signs), but on the authority of someone else: usually villagers, hunters, protected area personnel or local government staff. ...

Effective methods for estimating occurrence and abundance of carnivores are limited and often expensive in labour or equipment. Conducting interviews about wildlife species, including carnivores, is a common tool used in Borneo and throughout Southeast Asia to investigate species distribution and understand their conservation status. Such surveys are appealing because of perceived savings in time and equipment; however, biases in amount of available information, miscommunications about species of interest, and species misidentifi cation can result in errors of unknown magnitude, rendering results of at least some surveys suspect. Hence, it becomes diffi cult to disentangle accurate from inaccurate information. Studies are needed to investigate the variation in effectiveness of interview surveys. Also better guidance is needed to clarify under which conditions secondary surveys can be used with confi dence, and for which particular audience. Until the factors that bias results are identifi ed and, where possible, accounted for, the main use of secondary surveys for carnivores and other diffi cult to identify or rarely encountered species will be to help develop a dialogue between people that reside or work in conservation project areas and the investigators working on such projects. Secondary surveys may also serve as a tool to help identify hypotheses to be addressed in studies with strong experimental designs.

This book describes one of our closest relatives, the orangutan, and the only extant great ape in Asia. It is increasingly clear that orangutan populations show extensive variation in behavioral ecology, morphology, life history, and genes. Indeed, on the strength of the latest genetic and morphological evidence, it has been proposed that orangutans actually constitute two species which diverged more than a million years ago — one on the island of Sumatra the other on Borneo, with the latter comprising three subspecies. This book has two main aims. The first is to carefully compare data from every orangutan research site, examining the differences and similarities between orangutan species, subspecies and populations. The second is to develop a theoretical framework in which these differences and similarities can be explained. To achieve these goals the book synthesizes and compares the data, quantify the similarities or differences, and seeks to explain them.

The tiger has always had a considerable impact on human cultures, especially where people and tigers have lived together and still do co-exist. It is certainly one of the most easily recognizable cats, with its distinctive and unique striped coat and is also commonly believed to be the biggest cat species alive today, although this claim is questionable. The tiger shows considerable variation in its size, coloration and markings, reflecting the variety of habitats it occupies throughout its wide geographical distribution from the temperate oak forests of the north to the humid tropical forests on the Equator. Understanding this variation is a key to its successful current and future conservation, but people are still uncertain of its significance. Its large size and consequent need for large prey have brought it into conflict with people by preying on them and their livestock, but it has also earned our respect and admiration for its power and prowess as a killer. Research on geographical variation in tigers is suggesting two possible models, which have enormous significance for future tiger conservation. The more conservative model, based both on molecular and morphological research, suggests that eight or more subspecies, some of which may even be distinct phylogenetic species, should be recognized.

The evolutionary fitness of any predator, whether it is a spider catching insects or a lion hunting buffalo, depends largely on the quality and quantity of its diet. Predatory strategies are shaped and refined by natural selection to maximize nutrient intake within the bounds of a wide range of ecological constraints (e.g., prey density, habitat) that may differ dramatically for the same species at the extremes of its geographical distribution. The basic task of finding and gathering food under these constraints fundamentally affects a species’ spacing patterns and the structure of its social systems.

INTRODUCTION The present paper contains notes on some recent cats in the collections of the Rijksmuseum van Natuurlijke Historie, Leiden, as well as descriptions of the fossil Felidae in the "Collectie Dubois", Leiden, which its Director Prof. Dubois entrusted to me. The fossils were collected in Java 1) by Prof. Eug. Dubois during his searches for remains of the precursor of man, and with the intention to gather data about the geological age and ecology of this precursor (cf. Dubois, 1888). The age of the deposits from which the fossil cats were collected, has been much discussed. A review of the literature (up to 1931) on this subject has been given by Van Es (1931), who concludes that the Trinilfauna must be referred to the lower plistocene age, while Van der Maarel (1932) believes the Trinil-fauna to belong to the middle-plistocene. In a recent paper Von Koenigswald (1934) arrives at the conclusion that the plistocene mammal-fauna of Java in reality consists of three distinct faunae of different age: 1. the old plistocene Djetis-fauna, 2. the Trinil-fauna in its restricted sense of middle-plistocene age, and 3. the young-plistocene Ngandong-fauna. The latter in his opinion is connected with the recent javanese fauna by the prehistoric Sampoeng-fauna, which was described by Dammerman (1932, 1934 a, 1934 b). To this I may add that Prof. Dubois after his extensive studies on this subject, arrives at the conclusion that the Trinil-fauna belongs paleontologically to the youngest pliocene, geologically to the oldest plistocene, in the European sense of these terms. In connection with the age of the Trinil-fauna it was to be expected,
