For us humans, there’s something relaxing about the sound of moving water—think of the burbling of a stream, rain tapping on the roof, ocean waves gently lapping at the shore. Birds, on the other hand, are excited by it. So, if your birdbath is quiet, break its silence, and you’ll turn it into a bird magnet—they’ll find it irresistible, and you’ll see a lot more activity (this is true for any water feature). Here are several appliances that’ll make water move.
Bubbler
The job of a bubbler is to roil water so that it’ll produce bubbles. They’re typically solar-powered, and there are many styles, from plain to elaborate.
Water agitator
Set one of these in the center of your birdbath to produce continuous, gentle ripples. Available as solar-powered or with batteries.
Dripper
The sound of dripping water also attracts birds. The dripper must be connected to a water source, usually a garden hose. (You can find instructions online for do-it-yourself drippers made from plastic bottles, but keep in mind that plastic is toxic—current research suggests that even BPA-free plastics may be unsafe. )
Mister
This does just what its name says. If you can position it so your birdbath will catch falling droplets and nearby foliage also gets wet, the birds will be very happy, indeed! Some will soak in the drips and ripples in the birdbath water, some will bathe in the mist, and others will “wash” themselves in wet leaves.
Fountains, water features
A fountain or water feature is a wonderful alternative to a birdbath. If you want the birds to bathe, there must be a shallow area for doing that. Most birds bathe in water only 0.5–2.0 inches (13–51 mm) deep.
