it is found everywhere in the woods. In the spring it fre- 
quents the swampy woods, and is more shy. Arrives from 
the south from April 9th to 22d; remains about two weeks, 
when it departs northward. Arrives from the north about 
October Ist. Becomes very plentiful by the 10th. By the 
1st of November the greater part disappear, although a few 
remain until quite late in the month. Have taken it in 
Coos County, northern New Hampshire, on October 31st, 
although the ground was covered with snow six inches deep 
at the time! also in Oxford County, Maine, as late as No- 
vember 6th. ; 
T have never heard it give any note, except a low chirp 
of alarm, while passing through Massachusetts. A few 
yndoubtedly breed here. I have seen it at Hyannis on 
duly 3, 1868. There is also a nest containing four eggs, 
jabelled as beionging to this bird, collected at North Bev- 
erly, June 14, 1868, by Mr. E. P. Emmerton, in the mu- 
seum of the Peabody Academy of Science at Salem.

Tawny Thrush, ‘‘ Veery.” Common summer resident. <Ar- 
rives from April 30th to May 12th; leaves about the Ist 
of September. Found everywhere in the woods, where it 
breeds abundantly. 
6. Turdus Swainsonii, Cas. -—Olive-backed Thrush. 
Rather rare spring and autumn migrant. Have taken it 
from May 16th to June 1st in spring, and in autumn from 
September 25th until October 9th. Frequents thick, swampy 
woods and thickets, where, from its shy and retiring habits, 
it 1s very difficult to detect. This bird is quite variable in 
size and intensity of color, insomuch that ornithologists have 
long considered specimens of a somewhat larger size (al- 
though not always) and of a universally pale color, a “new” 
and a “good species,” called the ‘‘Gray-cheeked Thrush” 
(Turdus Alicie, Baird). It is strange that when the wide 
differences in this family are so well known and so generally
