Yesterday, I set up a new birdbath in my backyard. Instead of using the pedestal, I placed the bowl directly on the ground, partly beneath some cedars. I then installed a 1/4″ diameter plastic tube above the bath, hooking the tube up to my garden hose (using some parts I purchased at a plumbing supply store). I adjusted the flow so that the water slowly drips into the birdbath from the tube. I have seen this kind of setup before and know how amazing it is at attracting birds. For whatever reason, they are easily attracted to the sound of dripping water.
I didn’t have to wait long before the first visitors arrived. A group of three chickadees showed up first, followed by an American Goldfinch and then two migrants, a Chestnut-sided Warbler and a Nashville Warbler. I have never had warblers visit my regular birdbath, so I can only conclude that they found the dripping sound irresistible. On September 6, another Chestnut-sided showed up, as well as a Magnolia Warbler.
