Critically Endangered Animals
From WikiPilipinas: The Hip 'n Free Philippine Encyclopedia
The International Union for the Conservation of Nature and Natural Resources' (IUCN) Red List of Threatened Species (also known as the IUCN Red List or Red Data List) is the most comprehensive listing of the conservation status of animal and plant species globally. It is based upon a set of criteria to evaluate the extinction risk of thousands of species and subspecies. These standards are deemed relevant to all species and all regions of the world.
The IUCN Red List is assessed by the Species Survival Commission, overseen by the Biodiversity Assessments Sub-Committee (BASC). The list is made in order to raise awareness and concern on worldwide biodiversity.
In 4 May 2006 an updated Red List was released, which included the list of critically endangered animals found in the Philippines. The list included the following fauna.
 Critically Endangered Animals of the Philippines
- Philippine Eagle (Pithecophaga jefferyi). Also known as the "Monkey-eating Eagle' or "Haribon," the Philippine Eagle is one of the rarest, largest and most powerful birds of the world. Its population is rapidly declining, with an estimated population of around 250 mature individuals. This bird is endemic to the Philippines.
- Isabela Oriole (Oriolus isabellae). The Isabela Oriole is endemic to Luzon, with populations spotted in the province of Bataan and in the northeast parts of the island. The destruction of lowland forests is assumed to be the main threat to the bird's existence.
- Dwarf Pygmy Goby (Pandaka pygmaea). Pandaka pygmaea, one of the world's smallest fishes in terms of mass, was discovered in Malabon River in Metro Manila. In 1996 it was assessed to be critically endangered.
- Visayan Warty Pig (Sus cebifrons). This pig species can be found only in the islands of Visayas, and thus, faces challenges to their survival in the wild, such as having a limited area to escape from predators, and the possible presence of invasive species.
- Mt. Isarog Striped Rat (Chrotomys gonzalesi) . This rodent is endemic to Mount Isarog in Northern Luzon, and is threatened by continuous habitat destruction.
- Philippine Cockatoo (Cacatua haematuropygia). This bird, identifiable by its red feathers around its vent, is endemic to the Philippines. Its population suffered a massive decline due to habitat destruction and trapping for cage-bird trade.
- Mindoro Bleeding-heart. (Gallicolumba platenae). Endemic to the island of Mindoro, this species of bleeding-heart has an extremely small and fragmented population. Habitat destruction and illegal trade contribute to their population decline.
- Hawksbill Sea Turtle (Eretmochelys imbricata). Continuous hunting and capture causes population decline in hawksbill sea turtle, despite its wide distribution. In the Philippines, hatchlings were sighted in the island of Boracay. 
- Philippine Bare-backed Fruit Bat (Dobsonia chapmani). This bat is found in the islands of Negros and Cebu, where they survive in small numbers. Continued conversion of forests into sugar plantations negatively affect their species count.
- Tamaraw (Bubalus mindorensis). The tamaraw is a small hoofed animal endemic to the island of Mindoro. It is the only bovine endemic to the Philippines, and the country's largest native land animal.
- Island Forest Frog (Platymantis insulata). This frog species is endemic to the South Gigante Island in central Philippines. Shifting agriculture and limestone quarrying are among the reasons identified which contribute to its decline.
- Risiocnemis seidenschwarzi. This damselfly species is endemic to Cebu, where an insect population was found near a stream. However, continued pollution of its habitat is threatening the insect's existence.
- Pait (Puntius amarus). Pait is one of the many ray-finned fishes identified as critically endangered in Lake Lanao. Some researchers even suggest the species' extinction.
- Cebu Flowerpecker (Dicaeum quadricolor). The Cebu flowerpecker is a small passerine bird endemic to Cebu. It was feared to have become extinct, but a population was rediscovered in 1992.
- Sulu Hornbill (Anthracoceros montani). One of the most threatened species in the country, the Sulu Hornbill is endemic to the tiny island of Sulu in Mindanao. It is highly threatened by the destruction of forests and uncontrolled hunting.
