First Nature’s 32 oz. Hummingbird Flower Feeder’s red base with attractive yellow flowers really draws the birds and the raised flowers discourage bees and wasps from entering the feeder. The perch provides the perfect position for birds to comfortably feed at any of the ten ports. The wide-mouth fluted reservoir is easy to fill and easy to clean. The patented two-part base twists apart for thorough cleaning. All parts may be washed in warm soapy water. (Do not put any parts of this feeder in a dishwasher.) We recommend you use First Nature’s Hummingbird Nectar Concentrate which you can easily mix right in the reservoir. In addition, this comes with an ant barrier to keep ants from swarming your feeder, which can be easily installed between the hanger and the hook and then filled with water.
