The triple suction cup mounting style and size of this feeder make it perfect for almost any window. The clear plastic feeder dome is adjustable to restrict larger birds. It also acts to protect birds and food from the rain and snow. The deep feed dish has a .75 pound capacity and several drainage holes that keep food dry and fresh if the rain drives in. Cleaning and filling is easy and convenient. Simply lift the feeder from the suction cups or open your window to add to the food dish. Children under 8 will need adult help. 8" wide, 8.5" tall.
