A song thrush is being used to help keep a public toilet clean in a shopping mall in Kunming, Yunnan Province.

The sound of birdsong indicates to the bird’s owner, Chen, who is responsible for cleaning the toilet, that it is clean.

But silence from the song thrush alerts Chen that the toilet needs cleaning.
