Food for wintering birds has been formulated so that each bird species that stays in the country for the winter can find suitable, energy-rich food. Sunflower seeds, which are readily consumed by most birds, provide a lot of energy. Likewise, pieces of peanuts, along with oilseeds such as niger seeds, rapeseed, and flaxseeds, meet the birds’ nutritional needs thanks to their high caloric content. The presence of wheat attracts many bird species to feeders. Ground corn makes the food accessible even to smaller individuals, while peas provide valuable protein. Raisins attract soft-billed birds like blackbirds, robins, and fieldfares to the feeders.
