With the leaves falling and temperatures cooling, supporting our garden birds has never been more important.

While keeping feeders topped up is vital as food becomes scarce, there's one simple step every gardener should take: putting up a nest box.

Post breeding season, you don't have to worry about disturbing active nests - so you can get boxes clean and ready to go. Birds also start looking for new sites for spring, so putting a box up now gives ample time for them to find and get used to it.

Some smaller birds, such as tits and wrens, use boxes as snug winter roosts, so they will benefit from a shelter straight away.

Boxes are available from many online retailers, or if you're feeling handy, you can always make your own. When it comes to putting up your nest box, placement is key. Here are some top tips from the BTO to make sure you're doing what's best for garden birds.

1. Don't put boxes too close together

    Nest boxes of the same type sited too close together may encourage acts of aggression between neighbours.

    2. Shelter your box from the weather

    The front of the nest box should be angled vertically or slightly downwards to prevent rain from entering. Make sure it's sheltered from prevailing wind, rain and strong sunlight.

    3. Erect 3 metres from the ground

    Small-hole boxes are best placed 1-3m above ground on tree trunks, but it's best to avoid sites where foliage obscures the entrance hole - a clear flight path is important. If there are no trees in your garden, place your box on the side of a shed or wall. Just make sure the box isn’t easily accessible to predators like cats or squirrels.

    4. Keep nest boxes away from bird feeders

    If you get several birds visiting your garden feeder, this can disrupt nesting pairs. Try to keep nest boxes away from feeders.

    5. Secure your nest box with non-rusting materials

    If fixing boxes to trees, galvanised wire can be used to tie the box to the trunk or hang it from a branch. Regularly inspect fittings to ensure the nest box remains securely attached.
