In October, 1959, Karl W. Kenyon, Research Biologist of the U.S. Fish and Wildlife Service, and the writers, spent three weeks in North Borneo observing wild primates. During this brief period, we questioned both European and native residents of the Colony on the relative abundance of orang-utans (Pongo pygmaeus) in various sectors, and we carefully recorded such indications as we ourselves noted. Although our own encounters with wild orang-utans were limited, we saw numerous nests, many of recent construction. The results of our inquiries and observations were encouraging enough for us to conclude that the orang in North Borneo is, for the present, in no danger of extinction and that it survives in moderate numbers wherever suitable habitat exists. This in itself should offer sufficient inducement to afford every possible sort of protection to the North Bornean survivors of a species that, elsewhere within its comparatively limited range, is becoming scarce or has already disappeared altogether.
