Spring and early summer.
Concord, Mass.
1913.

47 Purple Finch. A male singing at the Farm, usually in
trees not far from the house, through April May and June as
well as during the latter half of March. On May 30 [May 30, 1913] I
saw a pair (the [male] adult) in the big red oak at the east end of
Ball's Hill.

48. Red Crossbill. Call note heard at Farm on April 4 [April 4, 1913]. On
July 2 [July 2, 1913] six birds circled low over the cabin at Ball's Hill
calling loudly.

49. Goldfinch. Seen frequently from March 22 [March 22, 1913] to July 2 [July 2, 1913], usually
at the Farm, in pairs and small flocks. In full song after
May 3 [May 3, 1913]. On June 28 [June 28, 1913] I saw 10 [males] & 4 [females] feeding together on
white mulberries in the tree in front of our house. [males] in full
plumage as early as May 18 [May 18, 1913].

50. Grass Finch. Arrived April 5 [April 5, 1913] (1 [in full song] at Farm). No marked
north-bound flight. Usual number of breeding birds, the [males] singing
freely through April & May. In June I heard them less often,
but by no means infrequently, to the close of the month.
As the season advanced their songs steadily improved in
sweetness and volume and were at their best towards the
very end of my stay.

51. White-throated Sparrow. Light migration this year. Saw
no more than a dozen birds in all, the first on April 21 [April 21, 1913],
the last on May 21 [May 21, 1913]. They sang but little.

52. Tree Sparrow. March 17 - April 16. Only about 20 seen
in all & never more than 4 or 5 in any one day.
Song heard only twice.
