Examples of animals on the International Union for Conservation of Nature's Red List of endangered species that live in rainforests include the giant panda, the great green macaw and the yellow-crested cockatoo, as of 2015. The IUCN estimates that the population of giant pandas is about 1,000 to 2,000, the population of great green macaws is less than 3,700, and the population of yellow-crested cockatoos is 1,500 to 7,000.
The giant panda's existence is fragile due to hunting by humans and the destruction of its habitat, the temperate bamboo rainforests of China. A female panda is able to conceive during only two to three days each spring. The species' babies are small and fragile, weighing about 3 to 5 ounces. It is difficult for the species to recover from such low numbers; many giant pandas are kept in zoos where zoologists attempt to induce breeding.
The great green macaw's numbers have continued to shrink in recent decades as a result of deforestation affecting the rainforests of Central America, capture for the pet trade, and subsistence hunting. In Costa Rica and Nicaragua, a campaign is underway to increase awareness of threats to the local ecology.
The population of yellow-crested cockatoos has rapidly declined in modern times as result of international trade in the species and ongoing deforestation in the rainforests of Timor-Leste and Indonesia. In recent years, some islands have seen an increase in the population as a result of restoration of mangrove swamps and increased conservation efforts and law enforcement.
