Birds can't be bought. The way to get more in the garden is to create the right conditions, and here's how.
How to encourage it
Plant berrying shrubs for an autumn and winter food source, and hedges for shelter and nesting sites. Leave seedheads standing for as long as possible, since they provide both seeds and the insects that gather on them. Ivy is particularly good for nest sites, used by house sparrows, robins and wrens among others. Bird boxes add further nesting options, including dedicated designs for declining species such as swifts and sparrows. Provide clean water year-round for drinking and bathing, and clean feeders regularly to stop disease spreading between visiting birds.
Different feeder foods draw different visitors. Nyjer seed is the one goldfinches and siskins go for; mealworms are especially popular with robins and blue tits, and can also draw other insect-eating birds such as pied wagtails; sunflower hearts suit finches like chaffinches and greenfinches; and suet-based food bars are a high-energy option that a wide range of species take, particularly useful in winter.
Avoid using pesticides in the garden: they remove the insects birds need to feed their young, not just the pest being targeted.
What it helps control
No single bird species targets any one of these pests specifically; garden birds are opportunistic feeders that take whatever's available, aphids, cabbage caterpillars and flea beetles among them. Almost half of UK bird species are currently in decline, and bird numbers overall are down by 73 million, almost a third, since 1970, so a garden that supports them is doing more than pest control.
Myths about birds
4 common claims about birds, checked: 2 busted0 disputed0 untested2 hold up
“Feeding garden birds seeds and peanuts all year round, the same way you do in winter, is best for them and helps them raise more chicks.”
The RSPB's own review of the evidence changed this advice: it no longer recommends putting out seeds and peanuts between May and November, because of the disease risk when birds cluster at feeders during the breeding season. Winter feeding (autumn through to spring) is still encouraged. During the breeding months, the RSPB only recommends small amounts of mealworms or suet products, in moderation, rather than the usual seed mix.
Our read The instinct behind the myth is sound, garden feeding does help, but the specifics matter: what you feed and when changes across the year, so a static winter routine kept up all summer isn't the safest version of it.
What to do: Keep seed and peanut feeders topped up from autumn to spring, then switch to small quantities of mealworms or suet in late spring and summer, and keep feeders and water clean throughout.

- RSPB, When to feed birdsFollowing a scientific review, the RSPB no longer recommends feeding seeds and peanuts between May and November because of the risk of disease transmission, though small amounts of mealworms and suet are fine in moderation during that period.
“If you touch a baby bird or fledgling, its parents will smell your scent on it and abandon or reject it.”
Bird parents will not abandon a chick because a human has touched it. The idea rests on birds having a strong sense of smell that they use to detect and reject their young, which isn't how most garden birds operate; parental care is driven by instinct and the chick's begging behaviour, not scent-matching.
What to do: If you find a healthy, feathered fledgling on the ground, it's normal, leave it alone or move it to nearby cover out of reach of cats; if you find a naked or unfeathered chick that's fallen from a nest, it's fine to pick it up and put it back if you can reach it safely.

“Blue tits are especially good at keeping caterpillar numbers down in the garden.”
Blue tits time their egg-laying to coincide with the spring flush of caterpillars, so their peak food demand lands exactly when caterpillars are most abundant. Caterpillars are described as a favourite food, alongside other insects, making blue tits one of the more consistent caterpillar predators among garden birds during the breeding season.
What to do: Put up a blue tit nest box away from direct sun and prevailing wind, and avoid pesticides on caterpillar-prone plants like brassicas and fruit trees so there's something for a nesting pair to feed on.

“Encouraging garden birds is a genuine way to help control aphids, caterpillars and other pests without reaching for pesticides.”
Birds are named as natural predators on separate pest-specific pages covering cabbage caterpillars and flea beetles, and sit within the broader natural-enemies approach recommended for aphids. No single bird species is a specialist on any one pest; garden birds are opportunistic and take whatever's available, which is what makes a bird-friendly garden a broadly useful part of pest management rather than a targeted fix.
What to do: Avoid pesticides, since they remove the insects birds need to feed their young along with the pest being targeted, and add berrying shrubs, hedges and standing seedheads so birds have year-round reasons to stay in the garden.

Frequently asked questions
Can I buy birds?
Not usefully: birds released into a garden with nothing to hold them there simply leave. Creating the right habitat and food source is what actually keeps a population around; see "How to encourage it" above.
Could birds actually cause a problem in my garden?
Occasionally, depending on what you're growing: see the note near the bottom of this page.
How do I know if birds are actually helping?
Watch the pest population, not the predator count: fewer aphids, cabbage white caterpillars, flea beetle, plum moth, brown scale, beet leaf miner over a few weeks is the real sign, not how many birds you can spot on a given day.
Birds are also seed and fruit pests: they eat brassica seedlings and soft fruit, so whether they help or hurt depends on what's growing that week.
