Finally, it's here – our species-appropriate robin nesting box, cat-proof! The bird nesting box is professionally adapted to the needs of robins and redstarts! Thanks to the peck-resistant double niche entrance and cat protection inside, the birds have the best conditions for breeding and raising their young 🐦! The marten/cat protection inside prevents predators from reaching the young birds with their paws! The slit entrance, popular with robins, made of stainless metal also serves as woodpecker protection and prevents larger birds from pecking open the entrance slits of your robin nesting box and displacing nesting robins.
