[填空题]On a summer evening I was caught in the crossfire of dueling wood thrushes, each defending his portion of the forest. Their chosen weapons were their voices; melodies were their ammunition. Each sought to wound the other’s pride, but their sweet fluting pierced only the evening silence. (71)

He needs no approving audience and can project his voice without resorting to a singing perch in the treetop. The brown-backed, speckle-breasted, eight-inch wood thrush only looks drab. All of his beauty is concentrated in his voice. Let the scarlet tanager take the prize as the forest’s flashiest dresser. Among his winged brethren, the song of the wood thrush has no equal. He sings more enchantingly than any bird I know. (72) On the trail, I often find myself stopping to admire the wood thrush’s gift.
