Nest of Vireo Noveboracensis
1875. MASS. (Middlesex Co.) [Middlesex County, Massachusetts]
June 11 [June 11, 1875] either as I shall try for the nest again
next week. Striking across the fields 
for the station I heard another [male]
singing and chasing him about for
a few minutes finally shot him
with the pistol. On one occasion I
stepped up on a tussock and found
him squatted flat on the mud beneath
one like a snipe or a woodcock. This 
bird was in a little sedgy sink in a
pasture where I never saw one before
though I have often been through the 
place. Here I heard singing all at
once C. Henslowii [Centronyx henslowii], C. passerinus [Coturniculus passerinus] and 
P. Savanna [Passerculus savanna]. Took the 6:35 train home.
  June 14 [June 14, 1875] Clear and cold with hight N.W. [Northwest] wind. Ther [Thermometer] at
sunrise only 40 [degrees] and heavy frosts reported
from portions of N.H. [New Hampshire] Rose early and
got off by 7, Charles driving me up
to the foot of the Belmont hill. Hunted
 for the nest of a pair of Contopus borealis
which have frequented the old haunt there
all the spring, but the birds had appar-
ently gone and I could find no
indications of a nest. From thence struck
up by the mill ponds and over into
Waltham. Hunted for some time very
carefully for the nest of a pair of Vireo
Noveboracensis that I had seen in a certain
spot in May and finally found it
suspended prettily between the forks of a
hazel and about 2 ft high. The [female] was
sitting on 4 perfectly fresh eggs and
