(House Wren) in rearing young while every now and then I 
found on the ground under an apple tree the egg of a Robin 
pierced with one or more small holes otherwise intact and 
retaining nearly or quite all its contents which would not have been 
the case had a Jay, a Crow, a Cuckoo or a Squirrel molested it.
All three eggs in a Chippy's nest well concealed among the foliage of 
a low drooping branch of an apple tree often visited by the Wrens 
were treated in this manner and of course deserted by the bird soon 
after they were laid. Here I am inclined to suspect, however 
reluctantly, that many wanton depredations of such a nature 
were committed by those Wrens since it is definitely known 
that they are given to similar practices elsewhere. They did 
not interfere in any way this year with the Phoebees [Phoebes] nesting 
in our wood shed although last year the [male] Wren caused 
these birds exceeding annoyance by filling it up with sticks 
from day to day, after the young had left it, however.

15. Black and White Creeper. - Arrived April 25 [April 25, 1913]. Less numerous than usual 
during migration. Only a very few remained to breed, perhaps two pairs in 
woods at Farm & another at Ball's Hill.

16 Golden-winged Warbler. - One heard singing at Farm near foot of lane
on May 14 [May 14, 1913] & another in Berry pasture on 21st [May 21, 1913]. None noted afterward.

17 Nashville Warbler. - Arrived April 27 [April 27, 1913]. No obvious north bound migrants 
noted. At least two [males] remained into June. On the 9th [June 9, 1913] heard one at the foot of lane, 
another in Birch Field. There was probably a nest in each of these places.

18 Tennessee Warbler. - At the Farm heard a [male] in full song in oaks behind barn 
on May 21 [May 21, 1913] (8-8.20 A.M.), 23rd [May 23, 1913] (whole forenoon), 24th [May 24, 1913] (through entire day), 25th [May 25, 1913]
in Berry pastures (8 A.M.). On 21st [May 21, 1913] had good view of bird, low down in elm.
