TOWNSEND AND ALLEN: LABRADOR BIRDS.

while he gave a sweet warbling song.” Of another bird, seen on 
November 25th, he said: ‘‘The Belmont bird was also well seen and 
gave a few notes of the warbling song.” At Cape Breton Island in 
August, 1905, Dr. Townsend heard in four different places a pleasant 
warbling song emitted by this species. ‘‘It was a low, bubbling, 
warbling song, which I vainly attempted to describe in my notes. 
It began with a pset or tsee) followed by a sweet but short warble” 
(Auk, vol. 23, 1906, p. 178). While this was in press, C. H. Clark 
wrote as follows in the Journal of the Maine ornithological society (vol. 
8, 1906, p. 27): ‘‘I ran into a flock of Hudsonian Chickadees (ten or 
twelve), and these, too, were exercising their voices, and mingled with 
the ‘dee, dee, dees,’ and ‘ehick-a-dee dees’ was a sweet little song 
of three or four notes and new to me, but I was not long in doubt as 
to what it was, for soon a Hudsonian came out on a limb not over 
three feet from my face and sang it right at me.” This was at Lubec, 
Maine, on February 11, 1906. Again in the same Journal (vol. 8, 
1906, p. 83) Dana W. Sweet records a pair of Hudsonian Chickadees 
on Mt. Abraham, near Phillips, Maine, on June 22, 1906. He says: 
“Twice I heard the song of the Hudsonian Chickadee.” Dr. Town¬ 
send wrote to Air. Sweet asking for fuller particulars. Air. Sweet kindly 
replied as follows under date of December 8, 1906: “I have never 
read anything about the notes of the Hudsonian Chickadee. . . .Janu¬ 
ary 19, 1905, I heard what I am very sure is the warbling song that 
you mention. At the time I was unable to describe it in my notes.... 
It was, however, entirely different from any other notes of either 
species. As I remember, it was a clear, sweet soprano, and was 
cpiite a remarkable performance from a musical standpoint.” 
Although we did not hear the song in Labrador, we heard at Bay 
of Islands, Newfoundland, on July 6, 1906, a song which Dr. Townsend 
recognized as the warbling song of this species he had heard the 
previous summer in Cape Breton. We are both agreed that it should 
be classed as “a warbling song” of considerable merit. We had 
been watching a pair of Hudsonian Chickadees with the hope of 
hearing them sing, but as the birds were concealed in the spruces at 
the time the song was heard, we could not be absolutely sure that one 
of these was the author. In speaking of the song Mr. Brewster 
(“Birds of the Cambridge region,” 1906, p. 379) says: “I have never 
heard anything of the kind from the Hudsonian Chickadee, although 
I am reasonably familiar with that species, having had abundant
