Bird Nest Boxes

Garden Bird Nest Boxes

Nest boxes play a vital role in supporting garden birds, providing safe breeding sites and shelter from harsh weather and predators.
With natural nesting cavities becoming more scarce due to habitat loss and modern building practices, well-placed nest boxes can significantly benefit bird populations.

Where and When to Site Nest Boxes

The placement of a nest box is crucial to its success.
Ideally, it should be positioned 2 - 4 metres above the ground, away from direct sunlight, prevailing winds, and predators such as cats and squirrels.
The entrance hole should face between north and east to avoid overheating in summer. Different species have different preferences - small hole entrances attract tits and sparrows, while open-fronted boxes suit robins and wrens.

Nest boxes should be installed in autumn or early winter, giving birds time to locate and inspect them before the breeding season starts in spring.
However, they can be put up at any time of year, as birds may take advantage of them immediately if natural nesting spots are in short supply.

The Role of Nest Boxes in Winter

During winter, nest boxes also serve as roosting sites, offering birds essential protection from cold temperatures, wind, and rain.
Species such as blue tits, great tits, and wrens frequently use them for overnight shelter, with wrens sometimes gathering in large numbers to conserve warmth.
Adding a small amount of wood shavings or dry moss can make a box more inviting for winter roosting.

By providing nest boxes, gardeners contribute to bird conservation while enjoying the benefits of increased bird activity in their outdoor spaces throughout the year.
