Very carefully, say scientists at the San Diego Wild Animal Park.
Zoologists hope to discover why.
Although the species has rebounded from a population low of some 200 individuals several decades ago, scientists say the Indian rhino is still jeopardized with extinction in its grassland habitat in India and Nepal. An estimated 2,400 survive in the wild. In an effort to expand the captive rhino population, an international team of scientists is using high-tech tools to identify reproductive problems in animals like Terai. To that end, the zoo has enlisted the help of world-renowned German veterinarians who are specialists in the reproduction of rhinos and elephants. Their level of expertise is much higher than what we have, even collectively.
