MADAGASCAN
Upland Rainforest

The higher altitude rainforests of Madagascar are cooler, and they offer a range of yet more endemic species to search for...

This is Madagascar, so as is the trend, there are many other invertebrate species that are endemic. A commonly seen large and spectacular moth found only on Madagascar and nearby Mayotte is the 'Suraka Silk Moth' Antherina suraka. This species is the only one of it's genus.

The rainforest of Madagascar has a fascinating diversity of endemic amphibians. The genus Aglyptodactylus includes six species of 'Madagascan Jumping Frogs', and are all endemic to Madagascar.

Apart from the lemurs, Madagascar is probably best known for it's Chameleons. Even though chameleons are found across the tropics of Asia and Africa, their centre of diversity is in Madagascar. Furcifer pardalis, 'Panther Chameleon' is one of the most commonly seen species, but across its range this species varies in pattern and colour.

There are not just large amd colourful chameleons, there are also tiny camouflaged ones. The genus Brookesia contains the 'Leaf Chameleons', tiny chameleons that live in the leaf litter of the rainforest.

There are other endemic rich groups of reptiles here, such as the family Gekkonidae. The genus Uroplatus contains the 'Flat-tailed Geckos' or 'Madagascan Leaf-tailed Geckos'. They are all endemic to the forests of Madagascar. There are more species than previously thought; some can only be distinguished in the field by the colour and patterns in their large eyeballs.

One of the areas where the endemism of Madagascar is very obvious is with the birds. There are some entire groups that are endemic to the island, such as the 'Ground Rollers'.

Another group endemic to Madagascar are the 'Asities' of the family Philepittidae. The two genera and four species are all endemic to Madagascar. They are sexually dimorphic, with the males developing colourful heads masks around the eyes. The colour is unique in the animal kingdom, as the pigmentation is provided by collagen fibres. Although they are one of Madagascar's few fruit eating (and thus seed dispersing) birds, they also have forked tongues for nectar collection.

The biggest family of birds in Madagascar are the Vanga. Although species in the family are also found in other parts of the old world tropics of Africa and Asia, it is Madagascar where they have radiated to an extraordinary degree. Species of bird in Madagascar that were once thought to be other types of birds such as Babblers, Bulbuls and Warblers, have been found to be Vangab that have evolved to fill different niches. This family offers some of the most amazing and easy to recognise examples of convergent evolution on the planet.

Other birds groups have representatives that are presumably relatively recent arrivals, and are only slightly different from their mainland counterparts. An example is the 'Malagasy Bulbul' Hypsipetes madagascariensis. The species here was split from the Black Bulbul, of which is looks quite similar. The Malagasy Bulbul is found in various wet and dry habitats across Madagascar, and with subspecies on surrounding island groups.

Places to experience the Madagascan upland rainforest

Madagascar has a number of national parks where you can explore the countries upland rainforest, including Amber Mountain National Park.
