A squirrel enjoys a dip in the cement bird bath, too.

A cement bird bath is a nice addition to your yard or garden and will attract a variety of wild birds to your yard. Cement bird baths are sturdy and last a long time, providing a place for birds to drink and cool off on a hot summer's day. Over time, you'll notice colorful mold growing in the bottom of your cement bird bath as a result of standing water, dirt and bacteria. Keep your bird bath looking nice and maintain it as a healthy place for wild birds by removing mold whenever it appears.
