Put an old frying pan or large shallow container out in your yard with some water in it for birds to to drink and bath in. Make it permanent if possible to build up the local bird-life's knowledge of where to come for a drink/bathe. Observe their 'pecking order' and interesting bathing and drinking methods - differing between birds. You could wok towards making a beautiful feature bird bath to sit and watch on Sabbaths. If you have frequently roaming cat in your yard this is not advised - unless you can make the bath out of reach from a stalking cat.
