Which birds turn up depends on your garden and the time of year. This is a guide to what this food is usually taken by, not a guarantee.
Sunflower hearts are dehusked sunflower seeds, so birds get straight to the good part without any mess or discarded husks littering your lawn or patio. High in oil and energy, they're a firm favourite with goldfinches and other finches, as well as robins, and because there's no shell to crack, they're easy for smaller-beaked birds to manage too.
The 4kg bag suits a household with one or two feeders on the go, giving you a few weeks of feeding before a top-up.
Miami Sunflower Heart Feeder
Built for hearts, with the right size ports to stop them pouring out.
Miami Seed Feeder
A standard seed feeder works too if you already have one up.
Feeders sold separately. Whatever you hang it from, site it within a short flight of a hedge or shrub — birds will not settle at a feeder with no cover to bolt to.
An estimate. Gardens vary with the season, the weather and how many feeders you keep going.
We allow about 6g of food a bird a day. Small garden birds take in roughly 3–7g a day in total, and a feeder supplies only part of that — the rest is insects, berries and whatever is growing nearby.
The bird numbers come from the RSPB's Big Garden Birdwatch. In January 2026, 9.4 million birds were counted across more than 650,000 gardens, an average of about 15 birds in a garden at any one time. We treat the birds you would see at once as the regulars using your feeders through the day. That is an assumption on our part, not a figure the survey provides. We are not connected with the RSPB.
A January count sits at the busy end of the year, so expect a bag to go further once natural food returns in summer. Squirrels and pigeons will empty a feeder far faster than any of this allows for.
No reviews yet. If you have fed this to your garden birds, tell other gardeners how you got on — it genuinely helps people pick the right food.
