A survey of endangered Javan rhinos in an Indonesian park has found far fewer females than males, a potential setback in efforts to save the species.
Video cameras set up in the eastern half of Ujung Kulon National Park recorded 17 rhinos this year. Just four were female.
Park official Arif Junaedi said Friday the cameras have now been moved to the more remote western half of the park, and that "hopefully many more females remain" there. The results should be known in November.
Only 40 to 60 Javan rhinos remain in the park, which is the animal's original habitat. They are the last known living members of the species, with none in captivity.
The last known Javan rhino in Vietnam was found dead in April, apparently after poachers killed it for its horn.
