Spring and early summer.
Concord, Mass.
1913.

36. Red-eyed Vireo. Arrived May 8 [May 8, 1913]. No marked flight of north-bound migrants
noticed. Breeding birds less numerous than usual. Walking from the Farm to
Ball's Hill I seldom or never heard more than 5 males. Two of them sang
near our house. Full, sustained singing did not begin until May 13 [May 13, 1913].
A nest deserted before completion was begun in an apple tree on June 1 [June 1, 1913]. I
found no other this year. No young seen or heard up to the date of my
final departure (July 2 [July 2, 1913]).

37. Solitary Vireo. - Arrival April 19 [April 19, 1913] ([male] [in full song] at Farm). No obvious flight of migrants
going further north. Breeding birds more numerous than for several years
past. I heard males singing near our farm buildings, in Pulpit Rock woods
(usually 2 there), at Ball's Hill (1) and Pine Hill (1). In Prescott's pines
there were three in fullest song and within hearing of one another on
the morning of May 11 [May 11, 1913] when on following up the song of one I
presently found the bird sitting in his nest which was at least 25 ft,
above the ground at the end of a long, heavily-foliaged branch of
a big white pine - a rather exceptional situation. When I visited the
place a few days later the nest was torn to shreds & the bird
gone. These Vireos sang well and freely, too, up to the very
end of June.

38. Yellow-throated Vireo. This has been the first year since
I bought the Barrett farm when it has been unblessed by the
constant presence in the breeding season of a pair of Yellow-
throated Vireos. It is true that a [male] appeared there on May 15 [May 15, 1913]
and was afterwards heard singing almost daily through
the month and occasionally up to the end of June, also,
but he did not, as a rule, frequent the immediate neighborhood
of the house and was often almost out of hearing from
it while his mate was never seen. I heard either him
or another near Bensen's on May 30 [May 30, 1913] & one near the Manse June 1 [June 1, 1913].
