Nepalese one-horned rhinoceros Kancha stands at the central zoo at Jawalakhel in Kathmandu. Nepal's only zoo has opened a new 'honeymoon suite' for its two one-horned rhinos in the hope of persuading the endangered pair to breed for the first time.

Kancha, 20 (pictured), and 22-year-old Kanchi have lived together in captivity for most of their adult lives, but have never bred -something the zoo's manager Sarita Jnawali attributes to the quality of their enclosure.

She hopes that their new, much larger home, which features mud rather than concrete floors and two large ponds for them to wallow in, will persuade them to finally start mating
