Baby panda

This image provided by the San Diego Zoo shows a giant panda cub receiving its first veterinary exam Thursday, Aug. 23, 2012, in San Diego. The exam allowed staff to determine that the cub is healthy, thriving and weighs 1.5 pounds, but were not able to determine the sex. This is the sixth giant panda born at the San Diego Zoo, the most born at a breeding facility outside of China.(AP Photo/San diego Zoo, Ken Bohn)
