Erect the nesting box as soon as you spot your first dandelion or if you spot a bluebird. Putting it up too early will only encourage pest species such as the house sparrow and European starling to take ownership of your box. These introduced species, which are aggressive and often drive off our native species, don’t require our help to survive.
Once the bluebirds have finished nesting for the season, clean out and take down nesting boxes until the spring. Alternatively, you can cover up the hole until it is time for the bluebirds to nest again.
