Adjust the wild bird food to the seasons. Depending on the season, the need for nutrients that should be contained in the loose food for garden birds changes. While the birds have an increased fat requirement on cold days, they need more protein in spring and summer. Food for wild birds from manufacturers such as MulitFit, PREMIERE or Versele-Laga take this into account in the composition of summer scattering food and bird feed in winter. For example, if the temperatures fall below freezing point, birds reach for fatty food. This is often enriched with soybean oil and provides enough energy on cold winter days for chaffinches, robins and thrushes, for example. Wild birds are also dependent on different types of feed. In general terms, a distinction is drawn between grain and soft foods. Natural goldfinch food therefore has different components from blackbird food. Scattered food mixtures contain something suitable for all birds.
