Spring and early summer.
Concord, Mass.
1913.

53  Chipping Sparrow. - Arrived April 12 [April 12, 1913]. Breeding in nearly if not quite their
usual numbers. At the Farm we had at least two pairs.  One reared an
early brood successfully in a nest built in a clematis vine on the front
porch of the Bungalow. Another laid three eggs in a nest in a drooping
mass of foliage at the end of an apple tree branch in the garden but
they were all pierced with small holes a few days later, I suspect
by one of our breeding House Wrens who was much given to foraging
for food in that particular tree. The contents of those eggs were not
removed. The 3 Chippies sang steadily through May & June. There was 
a third pair in the pasture across the road where I found their
nest & eggs in a little cedar near our well house. On June 10 [June 10, 1913]
I heard a [male] singing well back in Prescott pine woods. He may
have strayed there from Bensen's farm where one or two pairs breed.

54.  Field Sparrow. A male first heard in our Berry Pastures on April 12 [April 12, 1913]
sang there at intervals through April and up to May 25 [May 25, 1913] but
was either absent or silent for days in succession during both
months. Hence I doubt if he had a mate & nest there. This was
literally the only Field Sparrow noted by me anywhere in Concord this
year. On April 21 [April 21, 1913] he appeared with some Juncos under the front
windows of our house attracted there by millet and hemp seed which
he ate greedily.

55.  Junco. March 15 - April 30. Most numerous during first
half of April. Maximum number of birds - about 30 - seen
on April 2 [April 2, 1913].

56. Song Sparrow. No well-marked north-bound flight. Breeding
birds almost if not quite as numerous as they were last
year. At least three pairs settled at the Farm and perhaps
as many as five or six within hearing of Ball's Hill. Brood of 
young reared early in nest on ground near our hot bed.
