Geothlypis trichas - very common in moist thickets in brook
meadows and about the shores of ponds and
not at all uncommon among bushes bordering stour woods
and roadsides on high and perfectly dry ground. The
singing record is as follows: July 17[1]*18[2]*19[2]*20[3]*21[2]*
23[1]*24[1]*30[1]*August 5[1]*.
  Siurus aurocapillus - common in mixed woods and white pine
groves. In full song up to July 30th (July 11[1]*19[1]*20[3]*
24[1]*25[1]*29[1]*30[1]*).
  Setophaga ruticilla - Several pairs found in maple and birch
woods at the [delete]west[/delete] end of Cunningham Pond but
some noticed elsewhere. Not heard singing after July 12th.
  Vireo olivaceus - Probably the most abundant of the smaller
birds and of practically universal distribution but   
most numerous in mixed woods and old pastures
growing up to birches and maples. In full song everywhere
up to (and including) August 2nd" but on the 3rd & 4th,
although the weather continued fine, I did not hear
a single bird. It was as if an edict had gone forth
decreasing absolute silence of the entire region on these days.
Afterwards there was occasional singing as the following
record will show: August 5[1]*8[1]* (singing for a short
time at sunrise), 9[2]* (singing rather steadily at intervals
from 6 to 10 A.M.) 10[1]* (in full song much of the time
from 6 to 9 A.M.) 14[1]* (early morning) 15[1]* (do).
  Vireo solitarius - Found only in deep woods near the brook on Ben Mere
farm where two birds were singing near together July 24 and one
was heard on July 23, 25, 28 & 29 and on August 1, 2 & 3.
