Spinning Metal Garden Porch Hummingbird Mobile Windcatcher This hummingbird mobile, made from iron sheet, metal makes a great addition to a home or garden. The pieces are individually attached so that they move independently to each other in a 360 degree motion. Each piece is hung using swivels so that it only takes a slight breeze to trigger movement. This mobile is made up of plasma cut pieces that have been cleaned and painted with Rustoleum. The hummingbirds are red and the rest is black. It will add a splash of color to any indoor or outdoor space. It is approximately 26" long and has multiple pieces that sway and swivel when the wind blows.
