We have recorded a staggering number of birds feasting on Sunflower Hearts. Even \'non seed-eating\' birds such as thrushes, Robins and Blackbirds, who generally have difficulty opening the hard outer husks, have been seen merrily feeding away. During winter, a Blue Tit can spend up to 85% of the daytime feeding just to survive. By offering Kibbled Sunflower Hearts, time spent cracking open the husk is eliminated, enabling birds to save valuable time and feed more efficiently. We\'ve been astounded by the success of this food. The birds just love these smaller bite size pieces. As an added bonus there is virtually no waste, which means less cleaning for you. This food is available in a number of pack sizes - look out for the best value bulk buys!
