Overwintering birds need a diet rich in energy to get through the cold season. Frost and snow restrict their natural food intake, and urbanisation makes it increasingly difficult for them to survive on natural food sources. Especially in cities, wild birds benefit from supplementary feeding.Lillebro Sunflower Seeds for Wild Birds are a nutritious and energy-rich food which helps wild birds to cope with chilly winters. A natural source of vitamins and rich in oils, sunflower seeds are an important part of the supplementary wild bird diet.We recommend that you protect the bird feeding place from wind, rain and snow and clean it regularly. This will encourage the wild birds in your garden to keep coming back for more.
