Adorable Javan Rhino Calf Caught on Camera, One of About 80 Still Alive

Camera traps are instrumental for wildlife biologists and conservationists to monitor the health of animal populations. In some cases, camera traps even spot species that are seldom seen by people. In Java, Indonesia, a camera trap spied an adult Javan rhinoceros (Rhinoceros sondaicus) and her newborn calf -- a remarkably rare sighting of the critically endangered species.
