The bundle includes mini silhouettes of three iconic birds a swallow, a robin, and a great spotted woodpecker, which can be grouped together to create a lovely wildlife scene in your garden. Made of corten steel, a corrosion resistant material, this decorative silhouette is designed to last. Over time, the material forms a protective patina a green or brown coating that deepens and strengthens through the seasons. This coating will eventually become a dark brown or charcoal black hue for a natural, rustic look. Install your decorative metalbird baby bird bundle silhouettes on a tree or fence by holding them at a downward angle and gently tapping the stake into the wood with a hammer until secure. Packaged in a beautiful gift box, this rustic silhouette would make a unique gift for the wildlife enthusiast in your life. Corten steel contains over 70% recycled content, and all scrap steel from the manufacturing process is recycled.
