This window feeder is ideal for homes without a garden or limited outside space, it can be securely attached to a window with the 2 strong suction cups provided, allowing you to watch the birds feed from the comfort of your home. The transparent plastic ensures the birds are visible from every direction. Seeds and seed mixes will appeal to a wide variety of garden bird species. The wider variety of seeds on offer, the greater number of species you will attract. This feeder can be used to feed seeds, seed mixes, kibbled peanuts, chopped up suet treats, fat balls and fruits. We recommend whole peanuts are not fed from this feeder (always feed whole peanuts from a dedicated peanut feeder to prevent young birds choking on them).
