(Luscinia megarhynchos). Theodore Roosevelt once remarked that, "In melody, and above all in that finer, higher melody where the chords vibrate with the touch of eternal sorrow, [L. megarhynchos] cannot rank with such singers as the Wood Thrush and Hermit Thrush. The serene, ethereal beauty of the Hermit's song, rising and falling through the still evening under the archways of hoary mountain forests that have endured from time everlasting". A study published in 2014 presented evidence that hermit thrush songs, like human music, tend to be constructed of frequency ratios that are expressed as simple mathematical ratios and follow the harmonic series.
