Sunflower seeds present a high-energy, high-protein food source which is rich in the essential oils garden birds need to keep their feathers healthy and their beaks sharp; but they are often messy, leaving husks behind when the birds are done, and can germinate if dropped into fertile earth.
To avoid the frustration this causes some garden owners, many wild bird feed suppliers offer sunflower seed heart kernels, pre-husked so that your feathered friends can more easily finish their meals.
In our experience we have found Sunflower Hearts to be the single best bird food, loved and favoured over other foods by a wide range of birds. We believe the secret of their success is that sunflower heart seeds are a convenient size for most birds, birds don’t have to use valuable time and energy removing a husk and they have one of the highest calorie to size ratios and are filled with essential oils. Definitely the birds equivalent of fast food!! In addition the ease to eat them makes them a favourite of softbills such as Blackbirds, Robins and Song Thrushes.
