 to draw attention to their remarkable similarity. I : 

 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 Alicice 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 Bicknelli 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
