Birdbath

A birdbath is one of the easiest ways to bring birds up close, where you can get a really good look at them. You can attract even more species of birds with water than with a feeder.
Bird feeders usually cater to seed-eaters, such as cardinals, blue jays, and sparrows. Birds that eat insects or fruit, such as wrens, catbirds, and waxwings, usually don't find anything at the feeder to interest them. But the birdbath entices all kinds of birds, from robins to screech owls. It will expand your awareness of the variety of life.
A birdbath should be no deeper than three inches at the center. It should be even shallower at the edge, so that a bird can ease its way in. Cats like to lie in wait beneath shrubbery or behind a concealing object and then pounce on the birds when they're wet and can't fly well. So put your birdbath at least five to ten feet from such hiding places. Give the birds a chance to see the cat coming.
Make your birdbath easy to clean and refill. But locate your birdbath away from your feeding station, because seeds and droppings would soil the water quickly. Change the water every few days, or even every day in hot weather. Dump it out or squirt it out with the hose. I keep a scrub brush outside with my gardening tools, so that I can brush out any algae that begins to form.
