Forgotten Songs is a permanent public art installation comprising 180 bird cages that play a soundscape of birdsong. Commissioned by the City of Sydney, it was permanently installed at Angel Place in December 2011.
The calls are from bird species that used to live in the city before the arrival of Europeans.
During the day, you may hear the calls of the Eastern Whipbird, Rockwarbler, Regent Honeyeater, Grey Shrike-thrush, Fan-tailed Cuckoo, Spotted Pardalote, Brown Gerygone, Jacky Winter, Scarlet Robin and many others.
At night, the soundtrack switches to nocturnal birds like the Australian Owlet-nightjar, Powerful Owl, Southern Boobook, Barn Owl, Tawny Frogmouth, and White-throated Nightjar.
