The Natural World: Songbirds

By Tina Mitchell

Water hopscotching over rocks in a creek bed. Leaves crackling underfoot. A squirrel chatter-scolding as you walk past its tree. The slap of a beaver tail as its owner disappears under water while you move past its pond. The wind howling and swirling the new-fallen snow. Music in nature takes many forms, many tones, many timbres. But the featured artists in Nature’s symphony are the avian maestros.
