From the book

“See his early spring silhouette as he sings from the leafless treetops, his back slightly hunched, tail down and slightly forward of vertical . . . Spring’s here spring’s here, plant it plant it, in the ground in the ground, cover it up cover it up—doublet after doublet of short, whistled phrases pour from his bill.”

Just listen to the variety of brief doublet songs that the male thrasher sings in this three-minute offering. He can have as many as 2000 or more different songs!
