On which Philippine island can you find the Philippine Tarsier Sanctuary ?

Same source as #5: The Philippine Tarsier, as its name suggests, is endemic to the Philippine archipelago.[10] Tarsius syrichta populations are generally found in the southeastern part of the archipelago. Established populations are present particularly on the islands of Bohol, Samar, Leyte and Mindanao.[3] They have also been found on various isolated islands within its known range, such as Maripipi Island, Siargao Island, Basilan Island and Dinagat Island

The actual sanctuary I was asking about is on one of the islands you mentioned, Bohol.

Thanks for the answer !
