Researchers from the U.S. are trying to save the giant panda bear. The population is dwindling, so American experts have gone to China to learn how to keep them healthy in captivity.

The researchers are studying pandas in their natural habitat so they can transfer this knowledge to animals kept in captivity. The most difficult task is teaching the bears to breed in captivity. For some reason, the Chinese have had more success at it than many western zoos.

China has 13 panda reserves. There are only about 1,000 pandas left in the world.

The San Diego Zoo has a deal to import them from China. Researchers hope their trip will teach them how to help their bears flourish.
