High-oil black sunflower seeds which are popular with blue tits, great tits, greenfinches and chaffinches to name but a few.
Black sunflower seeds are excellent for use in bird feeders as they are free-flowing and prevent clogging in the tube. Sunflower seeds are full of essential natural oils which wild birds love. As they retain their outer husks they are suitable for birds which are able to strip them in order to access the inner hearts. Sparrows, tits, finches etc will love them. A good no-hassle way to feed your garden birds.
