 Sunflower HeartsGive garden birds maximum energy with minimum effort by choosing sunflower hearts - the tasty seed inside of the black sunflower seed. 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 in opening the outer husks, have been seen merrily feeding away. During winter a Blue Tit can spend up to 85% of daytime feeding just to survive. By feeding sunflower hearts, time spent cracking open the black sunflower husk is eliminated, enabling birds to save valuable time and feed more efficiently. |
