The Bitcoin Birds collection is 400 uniquely handmade pixel art birds. No two are exactly the same, and each one of them can be officially owned by a single person on the Stacks blockchain. Bitcoin Birds was created by 12-year-old Abraham Finlay as an extension of his love for birds and Bitcoin. He ultimately wants his digital birds to help physical birds. Abraham plans to donate a portion of the proceeds he receives from Bitcoin Birds towards helping wildlife.
