106 Faxon, Summer Birds of Berkshire County, Mass. [April 
74. Turdus mustelinus. Woop Turusu.—Common at lower levels 
and extending high up in the beech forest at the head of the Hopper. 
Also found sparingly at other points on the mountains. Noted on the 
Graylock carriage road near the three-mile board, altitude, 2400 feet (?). 
75. Turdus fuscescens. W1Lson’s THRUSH.—Common in the lower. 
cleared portions of the country, and observed at leastas high as 2000 feet 
from the sea-level on the cleared portions of the mountain sides. 
76. Turdus alicie bicknelli. BICKNELL’s GRAY-CHEEKED THRUSH.— 
On the third of July I visited the summit of Graylock, for the first time 
under favorable conditions of weather. I had barely reached the top 
when the chant of Bicknell’s Thrush was heard issuing from the 
thick growth of spruces, firs, and mountain ashes that skirt the clearing. 
The singer was perched upon oneof the larger spruces, perhaps twenty 
feet from the ground. AsI approached nearer he darted into the dense 
undergrowth of hobble-bushes and mountain maples. He proved to be 
so shy that it was not until my second subsequent visit to the mountain 
top (July 6) that I succeeded in shooting him. I therefore had ample 
opportunity to hear the song at short distance, for the bird was not 
chary of song when well concealed by intervening tree-trunks and 
foliage. The song is very much like that of Wilson’s Thrush in 
quality of tone, but quite different in form. In neither regard does it 
bear any close resemblance to the song of Swainson’s Thrush. It is intro- 
duced by two or three low clucks only to be heard at a short distance, 
which seem to the listener to be involuntary, mechanical sounds, like 
those that precede the song of the Whip-poor-will. The bird was shot 
while singing. The alarm or call-note of this species resembles the 
Veery’s, although distinguishable. It is entirely different from the 
abrupt whistle of the Olive-back. All of the Mylocichle are as readily 
distinguished by their call-notes as by their proper songs. What I take 
to be the equivalent note of the Hermit Thrush is not the low chuck com- 
monly heard while the bird is on its migration, but a peculiar sound which 
always suggests to mea Finch rather thana Thrush. The Bicknell’s Thrush 
on Graylock remained in the same place to my knowledge for four days 
in early July, in constant song. I do not doubt, therefore, that its nest. 
was near by. The condition of its testes, moreover, denoted a breeding bird. 
I failed to find a nest, however, nor did I see or hear another specimen 
although I visited the summit of Graylock on five subsequent days and 
carefully explored the other high points of the range. 
of this catalogue, 1835, Dexdroica maculosa and Sitta canadensis, both common in the 
Graylock region in summer, are also marked as breeding in Massachusetts, although 
not admitted in this 7o/e to recent lists until Mr. Allen’s revised catalogue of 1886, on 
Mr. Brewster's authority. In the light of the recent testimony to the accuracy of 
Emmons’s catalogue it is worthy of note that Dezdroica castanea is also marked by 
him as “breeding, rare.” Is it not possible that in Dr. Emmons'’s day, before the destruc- 
tion of the great coniferous forest of Graylock had gone very far, this bird found a 
congenial breeding ground there, as it still does in the White Mountains of New 
Hampshire?
