of the spruce grove along a mountain brook where smaller, 
thickly-growing spruces give place suddenly to large decidu¬ 
ous trees, mostly yellow birches and red and rock maples. 
“The male bird gleans his food largely from the tall 
spruces, and, from our study, it seems probable that he does 
not assist his mate in the care of the young or in incubation. 
“The patch of spruces in which these birds are nesting 
is situated just where the steep slope of the mountain be¬ 
gins. In shape its outline is irregular. It is about a half 
a mile across and is surrounded as a rule by a large decidu¬ 
ous growth. On the southwest a mountain stream tumbles 
rapidly along its border, and on the northeast a pasture, 
nearly overgrown with small spruces, adjoins it. The 
spruces in the grove grow thickly and range in size from a 
few inches to eighteen inches in diameter.” 
It is readily apparent that the Bay-breast is a large-sized 
member of the Dendroicae. It has been described by Gerald 
Thayer (see MSS notes quoted by F. M. Chapman in “The 
Warblers of North America”) as having a ‘‘Vireo-like lei¬ 
sureliness of movement,” which agrees with our estimate 
of the male's characteristics, but the female appears ex¬ 
tremely active, even more so than the Redstart. 
Chapman gives nesting dates for this species as June 15, 
Bangor, Maine (Knight) ; and June 9-14, Listowell, Ont. 
(Kells). These Monadnock birds are therefore very late, 
due perhaps to the fact that disaster overtook an earlier 
attempt to raise a family, or to the fact that a second brood 
was being raised. As far as I am aware there is no nesting 
record for this species on Monadnock or for any other point 
as far south in New England. 
In order to ascertain if the above-described occurrence 
of the Bay-breast here was accidental, Mrs. Whittle and I 
again visited the same spot on June 4, 1922. After some 
search a male Bay-breast was found singing less than fifty 
feet from his singing-tree of 1921. His song was given less 
frequently than the year previous and it seemed to be higher 
and thinner, resembling a variation of the Blackburnian 
Warbler's song. The female was not found. 
The male, as before, remained in the spruces all the time,
