Gardman Flip Top Sunflower Hearts Feeder is a refillable feeder designed for sunflower hearts for wild garden birds. The flip-top opening provides access for refilling. Hang it securely in a suitable location, clean it regularly and remove stale or spoiled food. Provide fresh drinking water nearby. Refillability does not make the feeder a permanent one-time purchase; continued reuse depends on it remaining clean, undamaged and serviceable.
