Updates from Africa: Madagascar part 2, Tana to Toilara

Antananarivo (Tana for short), the capital city of Madagascar, straddles a dozen or so hills high on the central plateau. Colorful houses dot the hillside and antique Renaults serving as taxis clog up the narrow roads with noise and exhaust. The reconstructed Queen's palace (it was destroyed by an act of arson in 1995) sits high on a hill commanding absolute attention and overseeing all the activity. Comically obnoxious Hollywood-esque letters advertise the city's name on the steep slope side below. There are zebu-carts running down dirt roads and green rice paddies farmed by families who live on less than $2 a day. All this is within walking distance of luxurious hotels where well dressed businesspeople drink and enjoy fancy French cuisine.

Starting from Tana the well traveled and popular Route Nationale 7 starts heading south along the central plateau. It winds its way through the highlands eventually turning southwest and dropping down before ending in the coastal town of Toliara. The whole trip is 799 km one way without side trips. Jake and I made the roundtrip journey in a silver station wagon with a Malagasy man named Lalah behind the wheel.

Eight hours south of Tana, halfway down RN7, there's a turnoff that takes you east to a town and national park both named Ranomafana. As popular and well studied as the park is today you would think it was the reason for the town's existence, but it wasn't actually even created until 1991. Ranomafana means hot water in Malagasy and it was these waters that drew visitors to this area in the days of colonization. Today the park trumps the water thanks to many amazing and fairly recent discoveries.

Upon arrival in Ranomafana we were met by our guide to devise the program for our visit. There was some confusion as we thought we were meeting a man named Emile and Lalah was convinced our guide's name was Rajeri. Emile Rajeriarison (Rajeri for short) turned out to be one person and an incredibly knowledgable guide. He has worked with many international researchers in the park, including American primatologist Patricia Wright, who with the help of Emile discovered the golden bamboo lemur in 1986, and German herpetologist Miguel Vences, along with whom he discovered multiple new species of frog. He has a very impressive resume and a great sense of humor. We were lucky he was free and were happy to pay his hefty guide fee in order to experience the forest with a true local expert for a few days. First thing, he introduced us to a group of golden bamboo lemurs. This endangered lemur subsists mainly on leaves and shoots of giant bamboo. These shoots have such high levels of cyanide that if other mammals consumed similar amounts it would be lethal. Incredibly high levels of cyanide have been found in their feces, and there is actually a species of dung beetle that specifically forages on their ultra-toxic poo. It's this strange and specific diet that allows them to live sympatrically with two other species of bamboo lemurs at Ranomafana.

Emile showed us all three bamboo lemurs and five other lemurs without even breaking a sweat. Although his real interest and expertise showed when he would disappear momentarily, reappear with a closed fist, and plop a beautiful little frog down in front of us along with more natural history than we could swallow. Names and facts came whizzing at us like mosquitos after nightfall, only unlike mosquitos there were no itchy welts left as reminders. Luckily there is a book for all that (and Emile had a hand in its existence). We didn't have nearly as much luck with the birds in the rainforest but luckily the primates made up for it. It rained on us every day and night, on the plus side the leeches were not nearly as bad as expected.

After Ranomafana we made our way back to RN7 and continued south. We passed an enjoyable afternoon in the small community run Anja Park surrounded by meowing ring-tailed lemurs. We spent a day at Isalo National Park climbing up sacred sandstone formations, hiking into slot canyons covered with hanging gardens, and diving into cool picturesque pools with plunging waterfalls. We made a quick visit to the small fragmented Zombitse National Park where we had an up close and personal performance by a young Verreaux's sifaka and found a squat Zombitse sportive lemur who somehow shoved himself in a tree hole half his size. We passed villages with bright red houses made with bricks from the blood red earth. We got stuck behind herds of zebu cattle driven by young men on foot, making their way from the south to the east where they can get a better price for their product. We saw Malagasy women with loads of produce on their heads walking to sell their wares at market day, each with a clean colorful hat made of raffia in their hand for when they arrive. In the highlands there were people selling plums and grapes, near Ranomafana it was eels and crayfish, and in Fianarantsoa where we were hoping for vanilla someone tried to sell us a Pachypodium, a native plant the locals call elephant's foot. As RN7 turned westward enormous centuries old baobab trees sprung up like beacons from the unnaturally barren landscape. Much of the native spiny forest has been cleared away for charcoal and the accompanying Verreaux's sifakas hunted. Only the highly saturated baobab is left, its water content too high to be of any use as fuelwood.

Eventually we reached the end of RN7 and were welcomed to the city of Toliara by high winds and sporadic downpours, the effects of a cyclone from the neighboring Mozambique Channel. We spent a few days in Toliara and the nearby coastal village of Mangily, 25 kilometers along a sandy road to the north. We visited a private protected patch of spiny forest and were presented with two more species of lemur, a magnificent long-tailed groundroller, a furtive subdesert mesite, and a timid little hedgehog tenrec. We didn't stay long at the beach as the cyclone mucked up the water and flung buckets of sand in our direction; nonetheless, Jake was quite pleased with the bonus seabirds that were blown in on the winds from the channel.

We are now back in Tana where we started. It took three long days retracing our steps on RN7 in that silver station wagon. Our memory cards are overloaded, our clothes are filthy, and our minds are spinning from all we experienced these past few weeks. In the end we tracked down about a quarter of the lemurs and 3/4 of the endemic birds of Madagascar. We couldn't check them all off this trip; we decided we'd better leave something for next time.

The lemur I longed to see the most, the aye-aye, truly is an elusive character and successfully eluded us this entire trip. Yesterday we made a visit to the zoo with hopes of finally catching a glimpse of one. The zoo houses six of these googly-eyed creatures of the night, but alas, the nocturnal lemur house is closed for repair for the next year. Aye aye aye, maybe next time.

Tomorrow we fly back to Nairobi and on Monday we are off to Istanbul. There we will meet up with my mother of the year to spend a week on the frigid shores of the Sea of Marmara. Luckily, she's bringing us both coats, I hear it's cold this time of year.

All the best from Antananarivo,
Corey & Jake
