Designed specifically for use with our Uncle Dunkels Bird Nest Material Holder, this all-natural, eco-friendly cotton provides birds with a safe and soft starter material for their nests.
Each replacement bag is filled with natural cotton, free of chemicals and synthetic materials, ensuring it's safe for birds to use in their homes. Refilling is easy: Simply slide up the wooden lid, add the replacement cotton, and place your holder back in its favorite spot.
Unlike manmade materials such as dryer lint, which can contain harmful residues and synthetic fibers, 100% cotton is a healthy, bird-friendly choice. This ensures that your local birds can build their nests with safe, breathable materials, supporting their wellbeing and encouraging vibrant bird activity in your yard.
