Birds know moving water means fresh water!  Unique agitator action creates continuous ripples in water.  Prevents mosquitoes from laying eggs in summer.  Use in winter with a heated bath to create a bird oasis.  Operates with two D size batteries, not included.  Includes wiggler and sage glazed ceramic cover.

Notes from The Front Range Birding Company:  One of our most popular products.  Batteries last a very long time.  The water wiggler is not strong enough to prevent water from freezing.
