Once a fascination largely for elderly gardeners and small children, finding joy in birdhouses and birdwatching is proving to be rather popular among all ages in 2025; in part for environmental reasons, and in part to help loosen the grip that screen-focused activities have on our consciousness.
You heard it here first – ornithology is officially in, and what better way to help support, chart and categorise new avian friends than with your very own decorative birdhouse?
Why are birdhouses important for local wildlife?
Contrary to popular belief, birdhouses are an important addition to local gardens and green spaces all year round – not just in spring. They offer essential shelter during harsher winter months, and – according to CJ Wildlife – encourage successful breeding the following spring by allowing birds to familiarise themselves with new nesting spots.
There aren’t always enough nooks and crannies to go around, which is where birdhouses come in.
Birdhouses are a haven for cavity-seeking avian friends. While some species of birds build intricate nests in tree branches, or rather sad-looking collections of twigs in city alleyways (pigeons, we’re talking about you), many species either look for or create holes in trees within which they can meticulously craft nests and lay eggs. A few examples of cavity-seeking birds in the UK include the Blue Tit and Great Tit, Starlings, Kestrels, Swifts and House Sparrows.
What to consider when setting up a birdhouse for the first time
Quality of materials: Birdboxes should have thick walls made from untreated wood to provide ample insulation. If decorated, always ensure it’s been done with non-toxic materials. Opt for a high-quality birdhouse with a hinged door to make cleaning easier throughout the year. Type of nesting box: Different birds, naturally, have different preferences when it comes to nesting. Some sources suggest avoiding birdhouses with perches, as they make it easier for predators to enter. According to BTO, hole-fronted boxes are suitable for smaller birds like Blue Tits, Coal Tits, and Marsh Tits (25mm hole), as well as Great Tits and Tree Sparrows (28mm hole). Larger birds like Starlings (45mm hole) and House Sparrows (32mm hole) require larger entrance holes. Open-fronted boxes are favoured by Robins, Wrens, Blackbirds, and Spotted Flycatchers. Placement: Prevailing winds, height and sun direction all play a vital part in where different bird species may choose to nest. Always place a birdhouse facing away from direct sunlight, as south-facing or exposed locations can overheat the birdhouse and harm young chicks. Ensure the house is sloped slightly downwards and protected from harsh winds or inclement weather. There should also be a clear, unobstructed flight path for birds to come and go as they please. Mounting: If you’re attaching a birdhouse to a tree trunk, doing so with screws or rope that are too tight may damage the tree. When mounting a birdhouse, always leave enough room for the trunk to grow, and regularly check the wire or rope to ensure the bark is protected. Galvanised wire is the recommended means of mounting, as it won’t rust. Some ornithologists pop a bit of old hosepipe or part of a rubber bike tyre in front of the wire to further protect the tree. Yearly maintenance/cleaning: Cleaning removes parasites, diseases, and old nesting material that can harm chicks or prevent future nesting attempts. The best time to clean birdhouses is at the end of the breeding season, which is typically in autumn between October and November, but it differs from species to species.
