Critically Endangered
Siau Island tarsier
Tarsius tumpara
Siau Island tarsier is a primate in the family Tarsiidae (order Primates) — Tarsius tumpara, recorded as Critically Endangered and tied to Indonesia.
Appearance
The main characteristics of the tumpara tarsiers include having a white ventral fur, lacking the distinctive golden dorsal fur of the Tarsius sangirensis, and having a larger skull compared to its other relatives.
The Siau Island tarsier is a very small species that measures around 4 to 6 inches (10–15 cm) in body length. Their long tails can add another 8 inches (20 cm) to their total length.
Range and habitat
The tarsier species are nocturnal and can be found sleeping in tree holes during the day, especially those of fig trees (Ficus), depending on what forest they are in. The Siau Island tarsier is a tarsier from the tiny volcanic island of Siau in Indonesia.
The Sangihe Islands are known for their critically endangered avifauna, and concerns about the conservation status of the Siau Island tarsier grew before its formal description. The Siau Island tarsier was selected for the list of "The World's 25 Most Endangered Primates" by the IUCN Species Survival Commission, Primate Specialist Group.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
In crisis
The progressive disappearance of its habitat, with the large population of the Siau people, restrains the primate communities within a small area. Other threats include the volcanic activities of the island, though most of these are interconnected and all play an important role in the endangerment of the tumpara tarsier.
