Over the past three years, I have been collecting audio recordings of giant pandas in San Diego and China. On Friday, April 16, 2011, I was able to record Bai Yun and Gao Gao during their breeding interactions. Giant pandas are primarily only vocal during the breeding season and use this form of communication as a type of courtship. A recording has been provided so that readers can have a listen.
In the clip, Gao Gao is bleating (sheep-like sound), and Bai Yun is chirping in response. Recordings like these have provided extensive information for our research and collaborative efforts with Zoo Atlanta and China.
