I saw something similar when I was looking for upcycling projects and this is my own take on what I saw. I really wanted a pair of old leather work boots for this project, but these canvas and rubber ones had the right shape. So I spray painted them.
Then I cut a hole and drilled a smaller one for the perch. I was lucky to find a cheap tin embossed plaque, and cut it in half, then bent it in half again. I taped the tin with painters tape so it had the shape I wanted and glued it to the top of the boot.
I used a metallic paint pen for the highlights and mounted it through the sole with screws to a cheap metal shelf bracket.
