Scientists In China Decode ‘Language’ Of Giant Panda

Chinese scientists who studied the language of giant pandas at a conservation center in the Sichuan province were able to decipher 13 different vocalizations. Researchers found that male giant pandas make ‘baa’ sounds like a sheep when wooing mate. The female giant pandas then respond by making bird-like sounds (chirping) when they’re interested.
Baby pandas (cubs) make ‘wow-wow’ sounds when they’re sad. When they’re hungry, the make ‘gee-gee’ sounds to prompt their mothers into action. Cubs also say ‘coo-coo’ which translate to ‘nice’ in human language.
The research team recorded the giant pandas‘ vocalizations in various scenarios which included nursing the cubs, fighting and eating to analyze the voiceprints.
“Trust me – our researchers were so confused when we began the project, they wondered if they were studying a panda, a bird, a dog, or a sheep,” said China Conservation and Research Center for the Giant Panda head Zhang Hemin, who lead the study. The research team has been analyzing panda linguistics since 2010.
Panda cubs learn to bark, shout, chirp, and squeak to express what they want. The researchers found that adult giant pandas are typically unsocial animals, making their mothers the only language teacher they ever had. When a mother panda won’t stop making bird-like sounds (chirping), she could be worried about her cubs. Like a dog, she barks when a stranger goes near her babies. In general, barking can be translated as “get out of my place.”
Understanding how giant pandas communicate can be valuable in their conservation, especially in their natural habitat in the wild. Findings coupled with conservation efforts will benefit future generations. Looking forward, the China Conservation and Research Center for the Giant Panda is looking into the creation of a “panda translator” using a voice-recognition software.
In the ocean, bottlenose dolphins and calves whistle to call each other when they’re out of visual contact: Mom calls Junior using his signature whistle, and he echoes it back in acknowledgement. In the Venezuelan jungle, when green-rumped parrotlets and their offspring get separated, they do the same thing as the dolphins: here.
China’s reforestation efforts have led to an increase in tree cover by 32 percent but the increase mostly comes from people turning former croplands into tree plantations with only one type of tree, which is of little value to wildlife. Likewise, native forests actually decreased by 6 percent because people continued to clear native forests to make way for tree plantations: here.
