RSPB Feeder mix is a great value wild bird seed blend that we've designed for putting into tubular seed feeders all year round. It's a nutritious mix of oil-rich black and striped sunflower seeds, husk-free oats and canary seed, that'll attract many garden birds such as blue tits, great tits and greenfinches.|We recommend using our Classic seed feeder or Easy-clean seed feeders with this bird food.
