Note DU — PREFACE TO THE EDITION OF 1814 (continued 2)

"The Mocking Bird (Turdus polyglottus, Linn.), the American nightingale. He has a voice full, strong, and musical, and capable of almost every modulation, from the clear mellow tones of the Wood Thrush, to the savage scream of the Bald Eagle. In measure and accent he faithfully follows his originals. In force and sweetness of expression he greatly improves upon them. In his native groves, his song rises pre-eminent over every competitor. Neither is his strain altogether imitative. His notes are bold and full, and varied seemingly beyond all limits. They consist of short expressions of two, three, or, at the most, five or six syllables; generally interspersed with imitations, and all of them uttered with great emphasis and rapidity, and continued with undiminished ardour for half an hour, or an hour at a time."—American Ornithology, by Wilson, Bonaparte, and Jardine, vol. i. p. 164, etc.—ED.
