Kitty this is such a lovely invention designed specifically for small birds! It’s a great idea to paint it to attract birds, so what colour or pattern would you paint it? Would you go green to blend in with the parks’ natural colours or would you try neon and bright colours to stand out? Every part of your invention holds a purpose, there are perching places to provide comfort and there is a piece of wood to stop wind blowing it away. Let your imagination run free and keep inventing!
