pages 246 with the following records and it is unnecessary 
to draw attention to their remarkable similarity. Besides 
the trivial difference of pitch, a matter at most of a major 
seventh (the smaller species having the higher voice), there 
remains only a final group of notes in the Bicknell song 
which has no place in that of the Veery.

Those ascending notes absolutely decide the species; no 
other bird but Bicknelli sings that song, how much or how 
little of it Alicia sings remains to be discovered, but that he 
must sing some of it, no matter how little, there can be no 
possible shadow of doubt, otherwise Bicknell could not 
be a subspecies of Alicia. 
The same effect of a ‘“‘silvery spiral thread of music” 
obtains in this bird’s song as it does in the Veery’s, the 
same vague, mysterious descent of three or four mixed 
tones but with the addition of a distinctly solitary one—or 
perhaps two—and a final uprising mixed tone. These two 
records obtained on Mt. Mansfield, Vermont, close to 
the Summit house, under the ‘‘Nose” and in the very 
midst of the breeding ground of Bicknell Thrushes show 
no very marked differences of structure:

The high C is the final C of the piano, and a practiced and 
musical ear will detect an initial tone in some songs even 
higher. But the actual pitch of the song is less important
