NIGHTINGALE AND H18 Rivas. — Contin. 
even the woods to echo with his melodious voice; and this delightful bird, 
scorning to be out-done, will not yield to any competitor, either of birds or 
men. The Woodlark is his greatest antagonist, between whom there 
sometimes happens such a contention for mastery, each striving to outvie 
the other, that, like true-bred cocks, they seem resolved to die rather than 
lose the victory. If the former carries it in stoutness and freeness of 
song, so does the latter in his pleasing variety of soft, warbling, har- 
monious notes, in which, to my fancy, none excels or is equal to him.” —

Nors. — Darwin himself must acknowledge the faculty of song in this 
talented family : — 
“A mocking-bird (Ifimus Orpheus), called by the inhabitants Calandria, 
is remarkable from possessing a song far superior to that of any other 
bird in the country ; indeed, it is nearly the only bird in South America 
which I have observed to take its stand for the purpose of singing. The 
song may be compared to that of the sedge warbler, but is more powerful, 
some harsh notes and some very high ones being mingled with a pleasant 
warbling. It is heard only during the spring. At other times its cry is 
harsh and far from harmonious.” — Darwin, C.: Journal of Researches, 
etc., p. 54. 
Mr. Minot says :— 
“T estimated that the nightingale had a most wonderful compass, and 
was the greatest of all bird vocalists, but with a less individual and 
exquisite genius than our wood thrush.” — Minot, H. D.: Eng. birds com- 
pared with American. (Am. Nat., vol. xiv., 1880, p. 563.) 
On the slopes of Olympus the song of the blue thrush 
is often mistaken for that of the nightingale. — Birds of 
the Levant. (Lclectie Mag., n. 8. vol. vii., 1868, pp. 114-119.) 
And was not the song thrush the rightful recipient of 
Cowper’s homage in his ode to the nightingale ? 
See Index, Organist. 
1 A French observer, whose name cannot now be recalled, finds that 
the nightingale’s compass is rarely more than an octave.
