Concord, Mass.
1902.
July 6
  Forenoon cloudy with several light showers; afternoon
clear& rather warm with S.E. wind. Evening cool.
  I spent last night at the cabin. I was awake
at daybreak this morning and for half an hour later but
heard few birds singing, a Veery, Phoebee, Black & White Creeper,
Red-winged Blackbird, Song Sparrow and Maryland Yellow-throat
being all that I now remember.
Ball's Hill
Birds singing at daybreak.
  In the afternoon most of the common birds sang
freely but I heard neither the Robin nor the Rose-breasted
Grosbeak. There were two Field sparrows and one Chippy
singing at the Farm and Red-eyed Vireos everywhere.
A Solitary Vireo (the first that I have heard since May)
was in full song in the Barrett woods (near the spring)
and a Yellow-throated Vireo on Davis's Hill. I heard
three Tanagers singing and saw a female.
Birds singing in afternoon
  Twice to-day I heard a Rose-breasted Grosbeak making
that peculiar outcry which the bird appears to utter only
during the breeding season when anxious for the safety of
her eggs or young. On one occasion to-day her voice was
mingled with the screaming of a Blue Jay which, no doubt,
was at or near her nest. I noted her cries on the spot
as follows:- Ke-her, Ki-her-hir, ker-her, her-ki-
her, her uttered very rapidly in shrill, almost piercing
tones.
Notes of Rose-breasted Grosbeak
  A Green Heron which I flushed this forenoon from
a ditch in the Barrett meadow gave a croaking
toc-toc-toc-toc-toc as it flew off. I have rendered
this cry hitherto as oc but the t sound was unmistakable
to-day.
