Hidden in a Sydney alleyway called Angel Place the songs of fifty different species of birds that were gradually forced out of the city as a result of European settlement can still be heard calling down from a canopy of birdcages. A permanent art exhibit, Forgotten Songs includes the installation of 120 birdcages suspended to look as if they’re floating in the sky, accompanied by recordings of the sounds of Sydney’s long lost birds.
