Singapore Hornbill Project:Known as “farmers of the forest”, hornbills play a crucial role in the spread and germination of the seeds from big-fruited forest trees. There are 54 species of hornbills in the world—23 in Africa and 31 in Asia (12 in Southeast Asia). Three species are believed to be native to Singapore—the Oriental Pied Hornbill (Anthracoceros albiros- tris), Rhinoceros Hornbill (Buceros rhinoceros), and Helmeted Hornbill (Rhinoplax vigil). Only the Oriental Pied Hornbill, a species common in Southeast Asia, remains extant in Singapore.
