RSPB Premium peanuts are just that - top-quality peanuts that are delicious and safe for garden birds to enjoy. Rich in protein and fat, they provide a high-energy favourite for a whole host of garden birds, particularly tits, finches and siskins. Aflatoxin Safety is our top priority, and as such we reject any peanuts containing detectable aflatoxin. Aflatoxin, sometimes found in poorer quality peanuts, can build up in birds' bodies, eventually leading to death. Birds Attracted Blue tit Coal tit Great tit Long-tailed tit Siskin
