Common UK garden birds, and what they mean for your feeder

Before you buy a speciality feeder or a box with an unusual hole, it helps to know which birds are already around. Most UK gardens see a fairly short list of regulars. This guide goes through them, not as a field guide, but as a way to match food and nest boxes to the birds you actually have.

It is deliberately not an identification guide. We have not written plumage descriptions, because the RSPB and BTO already do that well, with photos and calls. Each bird below links to, or is based on, an RSPB species page opened on 14 November 2026. For identification, use those pages.

Which birds are most common?

The RSPB’s Big Garden Birdwatch results page says house sparrows are “often the most commonly spotted garden birds” in the survey, and that goldfinches have become a regular in the top ten. The full ranked list on that page is an interactive leaderboard that did not come through when we opened it, so we are not reproducing a top ten here. Look at it there: it is updated each year and it is the best simple answer to “what will I see?”.

What follows is the short list most people mean by garden birds: tits, robin, blackbird, house sparrow, starling and goldfinch.

Blue tits and great tits

The RSPB’s blue tit page says they eat insects, caterpillars, seeds and berries, and enjoy peanuts and sunflower seeds from garden feeders. They nest in tree holes, nest boxes and other small cavities.

What it means for you: a hanging tube of sunflower hearts, or a mesh peanut feeder, in the cold months. A small-hole nest box. The BTO hole sizes for blue tits and great tits are in the nest box guide.

Robin

The RSPB’s robin page says they eat insects, worms, spiders and other small invertebrates, plus berries and fruit, and that they visit gardens for mealworms and suet. They follow gardeners to pick up worms and grubs that have been dug up.

What it means for you: robins do not use a box with a hole. The RSPB says they favour an open-fronted box. Those are covered in sparrow terraces and open-fronted boxes. For food, suet and mealworms rather than a seed tube.

Blackbird

The RSPB’s blackbird page calls them almost exclusively ground feeders, eating worms, insects, berries and fruit, often hopping on the ground or turning over leaves. They build a sturdy nest of twigs and mud, often low in shrubs and hedges.

What it means for you: a blackbird is not a nest-box bird and not a tube-feeder bird. Leaves left on a border, berrying shrubs and a dense hedge do more than a feeder. The current advice on bird tables, and how to help ground feeders without one, is in bird tables and ground feeding.

House sparrow

The RSPB’s house sparrow page says they eat seeds, grains, insects and scraps, and in gardens commonly feed on bird seed, especially millet and sunflower seeds. They like to be in colonies, and usually nest in cavities around buildings, including roof spaces, eaves, wall gaps and nest boxes. The RSPB says the house sparrow is on the UK Red List.

What it means for you: sparrows nest in groups, which is why a sparrow terrace exists. See sparrow terraces and open-fronted boxes. A seed mix with some smaller grains suits them in winter; the differences between mixes are in bird foods compared.

Starling

The RSPB’s starling page says their favourite foods are cranefly larvae and worms in short, grassy areas, that they readily visit feeders for suet pellets and fat balls, and that they nest in cavities in trees and rocks and often in house eaves and roofs. The starling is also on the Red List.

What it means for you: a patch of short lawn matters, and suet is the feeder food. Starlings need a larger hole than tits. The BTO figure is in starling boxes and larger holes.

Goldfinch

The RSPB’s goldfinch page says they mainly eat seeds, especially of thistles, teasels and dandelions, and visit garden feeders for sunflower hearts and nyjer. The page notes they are increasingly visiting bird tables and feeders. That line describes behaviour, not advice: the RSPB’s current feeding guidance is not to use bird tables at all, because of disease.

What it means for you: sunflower hearts in a hanging tube may be enough. Nyjer needs its own fine-port feeder. See nyjer feeders and goldfinches. Teasel heads left standing in autumn are natural food.

Turning the list into a plan

Look at which of these birds you already see, then work backwards:

1. Mostly tits and sparrows? A hanging sunflower-heart tube in the cold months, and a small-hole box or a terrace.
2. Robins and blackbirds? Natural food and cover first, suet in a cage, mealworms cleared by dusk, an open-fronted box hidden in a climber for robins.
3. Starlings? Short grass, suet, and a larger box.
4. Goldfinches? Hearts first, then a nyjer feeder if the hearts tube is crowded.

The seasonal rules for seed, peanuts and suet are the same whichever birds you have. They are in what to feed garden birds.

Why does this page not describe what each bird looks like?

Because the RSPB and BTO species pages already do, with photographs and calls. We would rather point you to them than write descriptions we have not checked.

Which bird am I most likely to see?

The RSPB says house sparrows are often the most commonly spotted bird in Big Garden Birdwatch. Gardens differ, so your own list may look different.

Do all these birds use nest boxes?

No. The RSPB says blue tits, house sparrows and starlings use cavities, including boxes. Robins prefer an open-fronted box. Blackbirds build in shrubs and hedges.
