birdbath
A shallow outdoor bowl of water where birds drink and bathe.
A birdbath is a shallow basin filled with water that people place in yards and gardens for birds to drink from and bathe in. Most birdbaths sit on top of a stand or pedestal, putting the water at a height where birds feel safe from cats and other predators.
Birds need to bathe regularly to keep their feathers clean and in good condition for flying. Watch a bird in a birdbath and you'll see it splash energetically, ducking its head under the water and fluttering its wings to spray water all over itself. After bathing, birds will often perch nearby and preen, using their beaks to smooth and arrange their wet feathers.
A good birdbath becomes a popular gathering spot in any yard. On a hot summer day, you might see robins, sparrows, cardinals, and blue jays all taking turns cooling off. The water needs to be changed regularly to keep it fresh and clean, and in winter, birdbaths can freeze solid unless they have a heater. Many people consider their birdbath one of the best ways to help local birds while observing these fascinating creatures up close.
