KAZIRANGA NATIONAL PARK, India: After a night of traditional music and dance, The Duke and the Duchess of Cambridge, headed out in a jeep Wednesday morning into the wilds of remote northeast India for a wildlife safari to see rhinos, elephants and more.

Dressed in cotton casuals and wearing local Assamese hand-woven gamochas, or scarves, around their necks, the British royal couple looked relaxed as they sat in the back of the open jeep driving through park during the hot and humid morning, local resident Ranjit Rajak said.

Prince William and his wife, the former Kate Middleton, spent several hours at the Kaziranga National Park in hopes of drawing attention to the plight of endangered animals, including the park’s 2,200-population of a rare, one-horned rhinos.

The animals are under threat from wildlife poachers and habitat loss. Already this year, six rhinos have been killed for their horns, after 20 were poached in 2015.

The royal couple was joined by a park official acting as a guide on a tour across dirt tracks, tall grasslands and thick evergreen forest.

V.S. Bhaskar, a top Assam state government official, said the royal couple saw rhinos, wild boars, buffalos, hog deer and a variety of birds. “They enjoyed the trip quite a lot. They were very happy,” he said.

Prince William asked the forest rangers about the conservation challenges they face, he said.

The rangers told him that the poachers were using sophisticated automatic weapons, whereas the forest guards had old rifles, which were being upgraded, Bhaskar said.
