The San Joaquin antelope ground squirrel is an endangered species included in the list. They are significantly decreasing in number due to destruction of habitat. These animals are found in southern California. Another endangered species included in the list are the Peruvian black spider monkeys. They are decreasing in numbers for the last three generations because of habitat destruction due to land development and hunting. In Hawaii, the nihoa millerbird is also dwindling in numbers because of the introduction of predators in the area. The red wolf is also considered and endangered species. Though it was introduced back to its natural habitat in North Carolina, it is still struggling to survive and increase in numbers.
The European Mink is decreasing in numbers due to diseases, invasive predators, hybridization and habitat loss. The Azorean bat is also an endangered species due to the colony disturbance and pesticide poisoning.
Walden’s Hornbill of the Philippines is also an endangered species because of the deforestation and hunting in their natural habitat. In the small Salibabu Island, the Talaud bear cuscus is also decreasing in number due to overhunting and habitat destruction.
The Malagasy giant jumping rat and the long-tailed big-footed mouse are endangered species I Africa. These species are decreasing in numbers due to hunting and deforestation.
A small marsupial called woylie is now an endangered species in Australia. It is on the brink of extinction due to invasive predation.

The northern rockhopper penguin is an animal in the Antarctic that is considered by the IUCN as an endangered species. Also the galapagose petrel is considered by the IUCN as an endangered species. Most of these animals are facing extinction because of the overhunting and destruction of their habitat. Global warming and climate change is also another reason for their decreasing number. With the melting of the polar caps because of climate change and global warming, there is a disruption in their natural habitat that may lead to their extinction.
