The 5-year-old rhino, Andalas, traveled from the Los Angeles Zoo in the United States to Jakarta's international airport on a two-day journey. The rhino was fed fresh green leaves upon arrival in the tropical island nation.
''He got bored toward the end and a little stir crazy,'' said Dr. Curtis Eng, a veterinarian from the Los Angeles Zoo who accompanied Andalas on the trip.
After a checkup, the rhino was to travel another 12 hours by truck and ferry to a sanctuary on Sumatra island, where females Rosa and Ratu await.
''He is young and still full of energy,'' said Arman Malonongan, Indonesia's director general of forest and wildlife conservation. "Let's just hope he falls in love there.''
The Sumatran rhino is considered the most threatened of the five rhino species, with less than 300 still alive in isolated pockets in the forests of Malaysia and Sumatra, which is also home to endangered tigers and elephants.
Rampant poaching for its horns – used in traditional Chinese medicines – and destruction of forests by farmers, illegal loggers and palm oil plantation companies has decimated their numbers.
