To attract goldfinches and sparrows to your garden in the UK, consider planting sunflowers, which are favored by various bird species. BBC Gardeners' World Magazine advises selecting single-flowered varieties with large centers and leaving the plants standing after flowering, as the seedheads will serve as natural birdfeeders into early winter. In addition to sunflowers, other bird-friendly plants like guelder rose, ivy, honeysuckle, roses, and crab apples can enhance your garden's appeal. To further enrich your garden for wildlife, experts recommend setting up bird feeders, providing fresh water, and adding nest boxes. Additionally, for those interested in attracting owls, reducing outdoor light pollution can create a more conducive environment for them, as bright lights can deter these nocturnal birds.
