I know of no bird except the white-throated spar- 

 row which sings continuously as " high " as Picker-

 uttered in the note E four octaves above middle 

 C." But Mr. Gibson would have more correctly 

 said E in the fourth octave above, because the treble 

 register ends at the fourth C above the middle 

 one. 



How phenomenally high both the Peabody bird 

 and the Pickering's frog sing we quickly learn if we

 but with greatly reduced force ; yet these little singers 

 in the wooded hollow have golden, liquid whistles
