Birds help keep our ecosystem healthy, so help keep birds healthy too with the More Birds® Bird Health+™ collection. Bird Health+™ products are made of bird-safe, BPA-free materials and recyclable parts. The More Birds® Bird Health+™ Diamond Hummingbird Feeder features soft ports and an integrated perch design that optimize the feeding angle and comfort for all species of hummingbirds. Hummingbirds easily feed from the bee guard ports, but bees and wasps are stopped right in their tracks. The Diamond features a spiral, glass nectar bottle and a colorful red top and base. The wide bottle opening and detachable flat base make filling easy and cleaning a breeze. The built-in ant moat stops ants right in their tracks, keeping precious nectar fresh for hungry hummingbirds. With a 30 oz. nectar capacity, the Diamond provides plenty of nectar to keep hummingbirds happy and coming back for more! For best results, use More Birds® Bird Health+™ nectar, which simulates natural nectar found in flowers.
