Here in our sanctuary, the Bubbler is very popular with the birds. Some folks have thought about having a bubbler but perhaps would like a less expensive alternative to consider for the warmer months. We found that adding a dripper to bird baths also effectively moves the water and attracts the birds. We have two working in the garden areas right now, alternating on timers. The birds learn very quickly when they will come on.
In the spring, I put together a thirteen-minute video on this topic for the Arrow Rock Birds and Bees Festival, coordinated by the team at the Missouri River Bird Observatory. Here is the video with a bit of history on our sanctuary and information on putting a dripper on a bird bath. Oh, and if you do, the birds will thank you for it!
Stay cool out there!
