Woodstone Zaragoza Nest Box 32mm - Grey

Give garden birds a safer place to nest

When birds have a safe place to breed, they are more likely to return year after year. This WoodStone nest box with a 32 mm entrance has been specially designed for slightly larger cavity-nesting birds, offering a secure and comfortable nesting site, with built-in protection against predators and a durable construction that lasts for years.

Made from insulating WoodStone and backed by a 10-year guarantee, it's a long-lasting way to support garden wildlife while giving birds the best possible start to the breeding season.

Built-in protection against predators

What makes this nest box stand out is its integrated marten protection. A specially shaped internal platform, positioned directly behind the entrance hole, helps prevent martens and other predators from reaching the nest, eggs or chicks.

This clever design provides extra peace of mind by creating a safer environment where birds can nest and raise their young with less disturbance.

Durable WoodStone construction

The nest box is made from WoodStone, a robust blend of concrete and FSC®-certified wood. This durable material is built to withstand the elements and offers excellent insulation and breathability, helping to maintain a stable internal temperature during both warm and cool weather.

The result is a comfortable nesting environment that supports successful breeding and means the nest box can remain outdoors for many years.

Designed for medium-sized cavity-nesting birds

The 32 mm entrance hole is perfectly sized for species such as great tits, house sparrows, tree sparrows and nuthatches, while helping to discourage larger bird species from entering.

The nest box is easy to install on a tree or wall, with rear mounting ribs providing extra stability. At the end of the breeding season, the removable front panel allows for quick and easy cleaning, ensuring the box is ready for its next residents.
