Emily Dickinson: "The Birds begun at Four o'clock..." As the first rays of sunlight fill the trees on a spring morning, a symphony of birdsong erupts. As early morning light extinguishes the stars, male birds begin to belt out their songs. One of the magical gifts of spring is the dawn song. Early in the morning, sparrows, chickadees, thrushes, finches, wrens, blackbirds, and warblers - like this Yellow Warbler - all sing at once. Learn more at BirdNote.org.
