The birdcage artwork is actually called “Forgotten Songs” by Michael Thomas Hill. It’s in a tiny laneway between two major Sydney CBD streets and the skyscrapers.
“As you stand underneath the birdcages you can hear the sounds of the birds that once inhabited Sydney before the city built up to what it is today. As day becomes night, the sounds of the birds change too!” (From: “Travelling with Nikki. A blog of my travels around the world.” https://www.travellingwithnikki.com/2014/03/angel-place-sydney/
The songs are recorded and depending on the time of day or night they play different versions.
Thanks for the much appreciated comments. It’s a great spot which I completely forgot was there. Luckily we have a great group leader!!!
Thanks for commenting. It’s an unusual little niche in the CBD!
Thanks for your comment. It is cool!
Thank you!
Thanks Rick.
