Many of the rainforest's birds, reptiles, amphibians and mammals are endangered. These include familiar animals, such as the chimpanzees of Central Africa, and relatively unknown animals, such as the elephant frog of Australia.The tropical rainforests are home to more species than any other terrestrial habitats.
Endangered rainforest birds include the hyacinth and Lear’s macaws of South America and the yellow-crested cockatoo of Indonesia. Habitat destruction is a serious problem for many of these birds, but some of them, particularly the hyacinth macaw, have also experienced population declines because of collection for the pet trade.
Worldwide amphibian populations have been declining for several years. Both the golden poison dart frog and the golden mantilla are endangered amphibians of the rainforest floor. The causes of amphibian decline are not clear in all cases and may stem from the combination of habitat destruction, fungi, climate change and collection.
Mammals such as the Javan rhinoceros and the Sumatran tiger are at risk of extinction. Both are hunted for their purported medicinal properties, but they also face increasingly fragmented habitats. The maned three-toed sloth and the pygmy three-toed sloth are two other animals that are disappearing from their tropical rainforest habitats.
