Yes, birds do use baths, both for bathing and fresh water. They are drawn to running or bubbling water, but that isn't a deal breaker. Keep the water fairly shallow and/or add in submerged rocks to accommodate different sizes of birds. Any container will work. I have one which is a hammered copper dish that I wedge in the crook of a tree. It is perhaps 1.5" deep. I've seen a simple set up of a tomato cage with a plant saucer sitting in the top ring. Look around and see what you might have that would work, then experiment with placement. Birds like some sort of cover - a nearby shrub or tree - so they can quickly hide if threatened. Some folks add copper pennies to their baths for keep algae growth down. I position my bird friendly water sources near a hose bib and just dump and refill frequently. Good luck on your stewardship. And welcome to NGA.
