Step 1: The Tin Can Base
I drilled on large hole to let the sound out, bolted in the bird mec and added a switch. I also made a mesh grill to cover the large hole.
Then I added some metal legs from some old alarm clock and mounted a plastic battery holder underneath.
Step 2: The Cage
Step 3: The Bird
I used alluminium for the tail and wings as it is also light in weight.
Then I covered parts of the bird in rubber,cut from old inner tubes, and superglued in place. The neck and legs were painted using acrylics, and small clock parts were added.
Step 4: Rusting
Step 5: How It Works
Another metal rod is glued into the top of the birds head.It passes freely through a hole in the lower part of the birds head and down through the neck to rest on the base.
So, as the body lowers, the top part of head appears to lift, and as the body rises, it appears to fall. As all of this in in sync to the birdsong,the bird appears to be singing. A small rod at the front of the beak stops the head from twisting.
The wings are fixed to the body by hinges, but supported in the middle by the two rods. As the body lifts, the wings lower and as the body falls, the wings lift.
Step 6: The Cage Fitted and Estonian Birds

Later I made two larger Steampunk Singing Birds for the Tallin Puppet Theatre,in Estonia. Youcan see a video of one of them here http://www.youtube.com/watch?v=vNKJOfqqnpE
