There is no set rule to what to feed the birds in Spring. However, natural sources from worms and berries are still quite sparse until earlier summer. Right now, they are hard-pressed to find steady food sources. Combine that with their incessant drive to mate and defend territories, and wild birds need as much help now as in winter.
Mealworms are an excellent source of protein and are one of the best foods you can give to birds in general. They are a natural source of sustenance all-year-round, and so too in spring. It provides an easy meal high in protein and fat.
Suet is a great fast food for birds and a great source of energy, enabling birds easy access to essential fats and energy ready for breeding and fledging. We have suet available in pellets, fat balls, blocks and cakes, suitable for many different feeders and we can guarantee they will be a favorite in your garden.
Sunflower hearts are highly nutritious and oil-rich and come without the husks of complete sunflower seeds. Specially treated to prevent any extraneous growth in the garden, sunflower hearts are a sure favourite among many different garden bird species.
RSPB advise: Feeding birds in the spring and summer may help them to raise their chicks more successfully. Remember, always put peanuts in a rigid mesh feeder, as large pieces of nut can choke baby birds.
