The multi-feeder holds up to 470g of seeds, mixes or live foods such as mealworms. The domed roof can be moved up and down on the central rod to allow or block birds of different sizes. At its highest position it will allow most garden birds to feed but still guard against rain. Or it can be lowered to restrict access to tits, robins, finches and sparrows, while keeping out greedier large birds such as starlings.
