The reservoir holds 20 ounces of nectar, and the metal base has three feeding ports.
A red plastic flower shape inserts into the ports and removes from the reservoir for refilling. Connect the included, 6" "S" hook to the blown glass loop on the top of the feeder, and hang it anywhere in your garden.
This feeder works on a vacuum principle. To minimize dripping, you must fill the feeder completely with nectar every time you fill it. The goal is to have no air trapped inside the feeder before flipping it upside down.
