A young Ibis perching on a parrot bracket shakes his head and turns away, starts nodding and turns back. It's not David Attenborough, but still nice to look at. Inspired by a wind chime I saw on a fair trade market. I had to try to make something alike from waste material. So I tried my way with recycling plastic bottles.
The trick is that the head hangs on a scale and is held up by a counter weight. With each breeze the bird turns, nods its head shakes its head. Its fun!
