This particular exhibit is a living art piece made up of 40 zebra finches jamming on electric guitars and cymbals at the Barbican, in London. The artist, Boursier-Mougenot creates a walk-though aviary for a flock of zebra finches, furnished with electric guitars and other musical instruments. As the birds go about their routine activities, perching on or feeding from the various pieces of equipment, they create a captivating, live soundscape.
This video is cute, because it shows a female zebra finch, building a nest on the guitar;
this video is a humorous remix of the original video (top);
