When you order First Nature's Stackable Hummingbird Feeder you'll receive two individual feeders, attached together to hang as one unit, providing a total of 32 feeding ports. However, you may choose to separate the two individual feeders and hang them in more than one location in your yard. The red base attracts inquisitive birds and you'll find the two-part bases make cleaning a breeze. The wide mouth of the clear reservoir makes it easy to fill and easy to clean with warm soapy water. The design of the feeding ports discourages bees and wasps. There is an ant moat built into the top of each feeder. Just fill with water before hanging and you'll discourage ants from getting to the nectar. An "S" hook is included on each feeder for hanging. For best results use First Nature Hummingbird Nectar.
