Lake Umbagog.

June 7
(no 2)
  The Swainson's Thrushes sang through the greater part of the
day in the rain. One within twenty yards of camp sang during
the entire forenoon with only the briefest intervals of silence and
apparently in the same place. There was something peculiarly
sad or mournful in the expression of his voice as it came
from out the gloomy, water-soaked forest. It moved me strangely
and not at all agreeably recalling old associations with these
northern forests - associations pleasant enough in themselves but
inexpressibly sad as brought back to me by the voice of this
Thrush. For an hour or more he interrupted my work and made
me utterly wretched. At the time I supposed that this effect
was due to the mood I happened to be in but next day 
the same bird sang in the same way and with the same
effect. The morning & evening singing about our camp has
seemed to me delightful and I have looked forward to it
through each day.

Swainson's Thrush[/margin]
  Although the Swainson's Thrushes had apparently all arrived &
taken up their summer quarters in the Pine Point woods
before we opened the camp (May 21) they were very silent
for the first week. Indeed during the remainder of May
I seldom heard more than one or two songs (not singers) in
any one day and these at daybreak or in the evening twilight.
General and sustained singing began quite abruptly on June 2
after which we heard the song everywhere we went and more
or less at all hours. But immediately about our camp the
birds were all more numerous than anywhere else. They invariably
opened the bird concert at daybreak & closed it in the late
evening twilight. I never heard one sing during the night.
These Umbagog Thrushes seem to me to sing differently from the
White Mountain birds. The song has, I think,more variations here.
