My new bird bath sat birdless for a full year - even through the most icy winter in years (I kept it thawed out) - not once did I actually see anybody stop by for a drink. And forget bathers. Desperate, I sprung for the basic model water wiggler and what a difference it made! That gentle movement does the trick! Now I have bath visitors all the time.
