Chinese wildlife workers wear giant panda costumes in preparation for releasing cubs into the wild at the Wolong National Nature Reserve in southwest China’s Sichuan Province.

They dressed up in a panda costume that smelled like bear urine in an attempt to mirror conditions they will encounter in the wild. Workers say the panda costume is important for helping the panda cubs practice get ready for life in the wild. Furthermore, sometimes the keepers even imitate wild giant pandas’ voice.
