The ant moat on top not only stops crawling insects from reaching the ports, but it also lays flat so it is easy to fill. The glass bottle is a beautiful design and a great option for anyone who is looking for a long-lasting feeder. The perches are large and rounded to allow hummingbirds to perch comfortably while they eat from any of the 5 feeding ports. The base comes apart in 2 pieces, and the bottle has a large opening for easy cleaning.
