jewels AMONG THORNS SPINY FOREST BIRDS In a land already renowned for being ‘different’, the spiny forest of southern and south-western Madagascar is even more other-worldly, characterised by multiarmed octopus trees, spiky euphorbias and massive-trunked baobabs. And true to the island’s form, this arid habitat is rich in endemics, notably birds that bring their own suite of followers to the region. Charlie Gardner and Louise Jasper open this birders’ treasure chest.

The ground-rollers are another family that is entirely endemic to Madagascar, with four species occurring in rainforests and just one, the long-tailed, found in the country’s dry regions. A burrow-nesting bird whose haunting song is a highlight of the spiny forest at night, the longtailed ground-roller is restricted to a narrow coastal band in the Mikea area of the south-west and is classified as Vulnerable on the IUCN Red List. I MADAGASCAR Antananarivo INDIAN OCEAN Toliara Spiny forest Fort Dauphin N U 68 africa geographic • m aY 2 0 1 3 t’s early morning in the spiny forest and as the sun illuminates the uppermost limbs of the cactus-like octopus trees it reveals a singing bird atop almost every one: here a magpie-robin crisp in its pied butler’s uniform, there a Madagascar fody burning bright scarlet like a Christmas bauble, and everywhere stripe-throated jeries singing their hearts out in their eternal quest to defend their territories. Suddenly a bizarre cacophony erupts from within the dense thicket of thorns, a complex and richly layered chorus of whistles and trills that sounds for all the world as if a party of frogs and crickets has gathered in a cave for a singsong. After an eerie half-minute the song begins to fade – but then starts again, much closer this time, and our excitement builds as we realise that the authors of this crazy chorus are about to be revealed. Resembling an odd amalgam of rail, quail and dove, a subdesert mesite scurries across the path in front of us, quickly followed by three more. Even in a forest full of oddities, this mesite is one of the strangest birds around – a real avian enigma. Like social primates and carnivores but no other bird species (as far as we know), the subdesert mesite listens to the choruses of rival groups to assess their group size and decide whether to fight or flee. And while being a cooperative breeder is in itself not unusual for a bird, the system employed by the mesite is so strange that, even after years of study, we still don’t fully understand it. In fact, so extraordinary are the subdesert mesite and its two sister species (the brown and the white-breasted mesites) that scientists don’t even know what their closest relatives are. Once thought to belong to the pigeon, pheasant or crane families, they are now believed to be the sole members of an order all their own, the Mesitornithiformes. T he mesites are just one of the unique and spectacular avian treasures that inhabit the spiny forest of southern Madagascar, an island so long isolated from Africa and India that more than 80 per cent of its species, both plant and animal, occur nowhere else. Even birds, the world’s great travellers, seem to have been unwilling to hop across the Mozambique Channel, with the result that more than OPPOSITE Part rail, part quail and part dove in appearance, the subdesert mesite has long confused scientists and birders alike. LEFT Octopus trees, of the family Didiereaceae, dominate Madagascar’s spiny forest landscapes and, with their multitude of thorns, give the forest its name. Many bird species sing from the tops of their branches in the breeding season. BELOW The spiny forest is home to a high diversity of reptiles and mammals as well as birds, among them the ring-tailed lemur. PREVIOUS SPREAD The ground-rollers are a spectacular family of birds that occur only in Madagascar. Of the five species, the long-tailed ground-roller is the only one that lives outside the country’s eastern rainforests. half of Madagascar’s breeding species are endemic – an unparalleled proportion for any comparable landmass. Not just species, but dozens of genera and subfamilies, and even five whole families, are endemic to the island and the nearby Comoros. Madagascar’s bird community is full of old relics, drifters and evolutionary experiments that could not have arisen – or survived – anywhere else on the planet. This much is clear in the spiny forest, where a dense, other-worldly vegetation of candelabra euphorbias, swollen baobabs and spine-encrusted octopus trees grows on ancient limestone plateaux and coastal dunes, each species displaying its own adaptations to the arid climate. A dry and unforgiving environment, the spiny forest is nevertheless dripping with life, and is recognised as one of the top 200 most important eco-regions in the world. Two of Madagascar’s most famous lemurs live here – the ring-tailed lemur and Verreaux’s sifaka – and the forest is home to 10 bird species whose global ranges fall entirely or almost entirely within its borders. These 10 local endemics have prompted BirdLife International to classify the spiny forest as an Endemic Bird Area (and therefore a global conservation priority) and they draw many hundreds of birders to the region every year. The subdesert mesite shares its habitat with the long-tailed ground-roller, a w w w. a f r i c a g e o g r a p h i c . c o m 69 SPINY FOREST BIRDS SPINY FOREST BIRDS BELOW With its smart black head and massive bill, the male Lafresnaye’s vanga is one of the spiny forest’s most striking birds. The female shows more white on the face. BOTTOM A recent addition to Madagascar’s bird list, the red-shouldered vanga has become one of the spiny forest’s most sought-after species. It can easily be found around Andatabo, Toliara’s Table Mountain. The vangas are perhaps the most celebrated of Madagascar’s endemic bird families, not least because they have been likened to Darwin’s finches on account of the variation in their bills – between them they boast a veritable Swiss Army knife of probes, pliers and nutcrackers. Recent genetic studies have revealed that the Vangidae is a much bigger family than we had previously realised and now encompasses species that had been placed in families as diverse as babblers, flycatchers and warblers. Twelve members of the Vangidae occur in the spiny forest, of which three are endemic to it. The handsome Lafresnaye’s vanga uses its massive bill to rip open bark as it searches for insects, but it can just as easily accomplish more delicate tasks with it, such as picking berries. The red-shouldered vanga, described as recently as 1997, has become an avian legend among visiting birders as they need to make a pilgrimage to the area around Andatabo – Toliara’s own Table Mountain – for any chance to see it. The plucky Archbold’s newtonia is the third endemic vanga, its sweet, confident song a constant companion on many walks through the region’s forests. Like the vangas, the Bernieridae is a catch-all family made up of species that until recently were thought to belong to other groups, in this case warblers, jeries, greenbuls and babblers. Few species occur in the south, but one, the enigmatic thamnornis, is a characteristic bird of the region. It skulks furtively in thick undergrowth for much of the year and is therefore a real challenge to see. Come the rainy season in November and December, though, the males proudly proclaim their presence, perching on prominent branches and singing a complex series of rattles, trills and fluty notes to attract a mate. Large, long-tailed birds rather resembling louries after a visit to a make-up artist, the couas are a vocal and prominent component of any walk in the spiny forest. The running coua and Verreaux’s coua are endemic to this habitat and are often seen presenting their rufflefeathered backs to the morning sun in winter, while the more widespread crested, giant, green-capped and Coquerel’s couas also occur in the region. The last on the list of spiny forest endemics are the only two that don’t belong to endemic genera and both are largely restricted to coastal dune systems. Luckily for more relaxed birdwatchers, the littoral rock-thrush and subdesert brush warbler can often be seen from the beach in some of the region’s seaside ‘resorts’. The vangas have been likened to Darwin’s finches on account of the variation in their bills – between them they boast a veritable Swiss Army knife of probes, pliers and nutcrackers Mikea Ranobe Mangily Ambondrolava Toliara Toliara harbour Tsinjoriake Protected Area Anakao and Nosy Ve N U Tsimanampesotse Spiny forest birding The spiny forest covers a huge area and is served by a terrible road system, so access to many parts of it is difficult. Most visitors base themselves in Toliara, from which all 10 local endemics can easily be found. The following sites around the town are good for endemics and other special birds; visits are best arranged through local hotels or tour operators in Toliara or the capital, Antananarivo. Mangily (Ifaty) The region’s most accessible and best-known birding site, Mangily has knowledgeable guides who can almost guarantee sightings of longtailed ground-roller and subdesert mesite year round, as well as Lafresnaye’s vanga, running coua, thamnornis, subdesert brush warbler and Archbold’s newtonia. Ranobe A ‘wilder’ alternative to Mangily, Ranobe has all the same bird species but no guides specialised in finding them. It is also probably the best place in the country for the elusive Madagascar cuckoo-falcon, and an excellent site for reptiles such as Labord’s chameleon and the Critically Endangered spider tortoise. Trips on the lake can produce pygmy goose, little bittern and the endemic subspecies of whitebacked duck. 70 africa geographic • m aY 2 0 1 3 Tsinjoriake Protected Area Red-shouldered vanga is most easily seen around Andatabo Mountain and along the road to St Augustin, where Verreaux’s coua, running coua and Lafresnaye’s vanga are also common. The coast around Sarodrano and St Augustin occasionally shelters Humblot’s heron and greater flamingo, and can be good for migrant waders. Anakao and Nosy Ve Littoral rock-thrush is common in this seaside resort, where it shares hotel gardens with Lafresnaye’s vanga and subdesert brush warbler. The offshore island of Nosy Ve hosts Madagascar’s only breeding colony of redtailed tropicbird and often holds good numbers of terns, migrant waders and crab plover. Mikea The Mikea coast is one of the most beautiful in the world, but access is only possible with the sturdiest of vehicles. Long-tailed groundroller and subdesert mesite are common and Verreaux’s coua and littoral rock-thrush have recently been recorded. Tsimanampesotse The beautiful soda lake of Tsimanampesotse (‘where there are no dolphins’) is home to Madagascar’s only breeding colony of flamingos and is a stronghold of the threatened Although it has only a tiny global range, the littoral rock-thrush is easily seen at many coastal ‘resorts’ in southern Madagascar, where it perches prominently on euphorbia shrubs. Madagascar plover. Red-shouldered vanga has been recorded, while Lafresnaye’s vanga and Verreaux’s coua are common. This is also an excellent site to see ring-tailed lemurs, the Critically Endangered radiated tortoise, blind cave fish and Grandidier’s vontsira, a mongoose-like carnivore that occurs nowhere else on earth. www.parcsmadagascar.com Ambondrolava A community-managed mangrove and marsh complex 20 minutes’ drive north of Toliara, Ambondrolava has the highest wetland bird diversity of any site in the region, with species including little bittern, Allen’s gallinule and Madagascar harrier. It has the region’s only purposebuilt bird hide and a wonderful boardwalk trail through the mangroves. www.honko.org Toliara harbour Perhaps the region’s best site for wader watching, Toliara harbour offers excellent viewing of Palearctic migrants such as Terek sandpiper, terns (including Saunders’) and the elusive but beautiful crab plover. Greater flamingos also turn up occasionally. r i c a geogr g e o g r a phic p h i c . co com w w w. a f ric 71 SPINY FOREST TRAVEL PACK BIRDS SPINY FOREST BIRDS A Madagascar M adagascar’s spiny forest is dominated by plants of the Didiereaceae family, which protect their small deciduous leaves with an armour of menacing thorns and spines that project directly from the branches. Occupying the hottest and driest regions of the country, the forest offers visitors a prickly welcome. So, do your research before a visit and check out Charlie Gardner and Louise Jasper’s list of ‘must-have’ paraphernalia. DON’T FORGET • Small change is essential in rural areas, because few people have change for the 10 000 ariary notes that the banks supply. • Visitors travelling independently should also bring a French phrasebook, since very few Malagasy people speak English. However, even French is rarely spoken in rural areas. Verreaux’s sifaka THE RIGHT GEAR • Thick-soled shoes or sandals to prevent spines piercing your feet. • Long trousers and a long-sleeved shirt to protect your skin against spiny bushes (although this is a trade-off, because it gets very hot). s beautiful and rich as the spiny forest is, it is also disappearing fast. The eco-region has suffered the highest deforestation rate in the country since 1990, thanks primarily to the slash-and-burn cultivation of maize, known locally as hatsake. Remaining forests are under extreme pressure as a source of fuel wood too; more than 90 per cent of urban households use charcoal to cook their daily meals and there are no eucalyptus or pine plantations in the spiny forest ecoregion – as there are in the country’s centre and east – to satisfy this demand. Although less destructive than slash-andburn because it targets only hardwood trees rather than clearing the forest completely, charcoal production is causing the degradation of vast areas of spiny forest around the major towns of Toliara and Taolagnaro (Fort Dauphin). It is not just the local demand for resources that threatens the forest though. Western overconsumption is also a driver of deforestation, as demonstrated by a recent huge increase in mining interest and agricultural ‘land grabs’ by foreign corporations looking to produce biofuels. The habitat of southern Madagascar’s unique birds is under pressure from all sides, and even the birds themselves fall prey to villagers, who hunt many species for food. It is essential to understand why forests are overexploited if we are to develop effective conservation strategies, but in the case of the spiny forest what we do know reveals something of a paradox. Rural communities are indeed the main drivers of deforestation and forest degradation throughout the region, yet forests play an important role in the lives of the Masikoro, Mahafaly, Tagnalagna and Tandroy people and are generally valued by them. Many forest sites are sacred because they house ancestral tombs or are home to spirits of various kinds, and zebu cattle can be safely hidden from rustlers in their dense vegetation. Forests serve as free supermarkets too, being a source of housing materials, timber, fuel wood, medicinal plants, wild fruits and tubers, string, glue and meat, among countless other goods, and thus help to bolster ABOVE, RIGHT The thamnornis was thought to be a warbler until recently, but is now known to belong to the Bernieridae, a family entirely endemic to Madagascar. Although common throughout the spiny forest, it is difficult to find when not singing. THIS IMAGE Once thought to occur only on the Mahafaly Plateau, Verreaux’s coua has recently been found at several new sites and is now thought to be far more widespread. • A wide-brimmed hat to protect your face and neck as the heat makes you sweat all your sunscreen off. • A Leatherman or other pocket multi-tool for pulling spines out of your shoes. • A small, soft brush for sweeping sand out of equipment like binoculars and cameras. • Insect repellant to ward off mosquitoes and sweat bees. • High-SPF sunscreen. c ap e un ion m art (3) GEAR RECOMMENDED BY SOUTH AFRICA’S FAVOURITE OUTDOOR STORE WIN!

The fast rattle of the subdesert brush warbler is a constant companion on walks in spiny forest near the coast. ABOVE Despite the dry climate and extremely poor soils, huge areas of spiny forest are burned each year by farmers looking to grow maize. Yields are generally poor, so even this massive destruction does not provide a way out of poverty. 74 africa geographic • m aY 2 0 1 3 the household economies of communities living in extreme poverty. Unfortunately forests can also be converted into cash, and for farmers whose crops have failed due to climate change, fishermen whose catches are dwindling, or young families needing a plot of land to eke out a living, the forest is the only bank that will grant them a withdrawal. On a more positive note, things are beginning to change in Madagascar. Pressure on the forests may still be high, but a number of conservation initiatives are under way that show signs of reversing this worrying trend. In 2003 the Malagasy government declared that it would triple the size of the country’s protected area system, and while for conservationists this was wonderful news, it was also a huge challenge, as most remaining forest areas are home to substantial human populations that depend on them for their subsistence and household income. Nearly 100 new protected areas are being established across the country, including several within the spiny forest, but they follow a radically different model from the strictly protected national parks and special reserves of the past. Instead of imposing a complete ban on the exploitation of resources, the managers of these new sanctuaries seek to accommodate the needs of local communities by permitting them to make sustainable use of the forest. Indeed, in many instances communities themselves are involved in managing the protected areas. Some of the spiny forest eco-region’s existing parks are also being expanded, including its flagship example, Tsimanampesotse. This is one of Africa’s oldest national parks, having been created in 1927, and has increased in size from 40 000 hectares in 2008 to more than 200 000 hectares today. Many of these protected areas are developing tourism infrastructure as a way to generate a little revenue for the communities that manage them, so it is now easier than ever for visitors to enjoy the region’s special birds and other unique wildlife (see ‘Spiny forest birding’, page 71). With a little luck and a lot of hard work, these initiatives and the numerous other conservation activities under way will help to safeguard some of the spiny forest for future generations – the lives of thousands of species and millions of people depend on it.
