🐞✗ Tested and false“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.
