The song has been described by Dr. Townsend in his Notes 
on the Birds of Cape Breton Island,* as follows (which 
inclines me to believe I have not heard the full song): 
‘‘Several times in different places I was treated to a pleas- 
ant little warble . . . which appeared to my companion 
and myself to easily merit the name of song. It was a low, 
bubbling, warbling song, which I vainly attempted to 
describe in my notes. It began with a pstt or tsee, followed 
by a sweet but short warble . . . quite different from the 
irregular rolling notes that the Black-cap occasionally 
emits.’”’ That would mean that the thin, rippling notes I 
heard from the Hudsonian could not be the full song and 
that my record above does not fairly represent it. Mr. 
Horace W. Wright also describes the song as he heard it at 
Ipswich, Mass., November 12, 1904 as a “‘sweet warbling 
song” and again, for another song heard in Belmont, 
November 25th, he uses the same terms.** But of one 
fact we may be certain, the differences between the various 
notes of the Black-cap and the Hudsonian are distinct and 
absolute, the call of the latter is a low-pitched, drawled 
pst, zee, zee, zee, that of the Black-cap is stck-a-dee-dee-dee. 
This difference may be easily recognized by any mountain 
climber or autumn visitor in the White Mountains who is 
fortunate enough to meet with the two species.
