Wikipedia
Bird bath

A bird bath is an artificial " puddle" or small shallow pond, created with a water-filled basin, in which birds may drink, bathe, and cool themselves. A bird bath can be a garden ornament, small reflecting pool, outdoor sculpture, and part of creating a vital wildlife garden.

A bird bath is an attraction for many different species of birds to visit gardens, especially during the summer and drought periods. Bird baths that provide a reliable source of water year round add to the popularity and "micro-habitat" support.
