A mister is a simple attachment that fits a regular garden hose that creates a fine mist when turned on. Hummingbirds, like all birds, will take a dip in the water of a birdbath, but a mister is nearly irresistible. Hummingbirds will often flit through the mist to clean themselves and then find a place to roost to preen and dry off. Misters are easy to find and use and are not major water users either so it is a win-win (this one is a favorite).
