Bird Watching: Why don't the birds use my bird bath and water wiggler?, 1 by Birdloverdeb

I am a new bird watcher and have found an area I think is protected well with small tree and small shrubs under it where I am scattering bird seed and have a hanging bird bath. Some song birds, especially cardinals, are now visiting regularly and eating the seed. However, I have yet to see a bird use the bird bath that is slightly tilted with sand paper type surface, and my husband created a drip system (clear juice bottle suspended overhead). I wonder if the drip system is scaring the birds? Picture attached. Ideas? Thoughts?
