Spring & early summer
Concord, Mass.
1913.

1. Wood Thrush. - A bird singing - mostly at morning and evening -
in the run near the foot of the lane at the Farm from May 18 [May 18, 1913]
to 23 [May 23, 1913], inclusive. I have not noted one there before since May 27
1910. The species bred there last in 1908.

2. Wilson's Thrush. Arrived May 9 [May 9, 1913]. First heard singing (in
Davis Swamp) on the evening of the 21st [May 21, 1913]. In fullest song
June 19 - 23. After they had settled down to breed I heard 
a male singing regularly at the Farm (either in the Berry
pasture or near foot of lane), another near the Barrett Spring,
one or two in Davis Swamp, two in Ball's Hill Swamp,
two in Pine Park Swamp and at least three in the 
swampy coverts opposite Ball's Hill on the West Bedford
shore near our storm boat house. Thus they were present
this year in normal if not maximum abundance. Their
singing seemed to improve in quality as the season
advanced & to be at its very best about June 20 [June 20, 1913].
