  Swainson's Thrushes are quite as numerous in
the woods bordering the southern end of the lake as they
were when I first knew it, despite the disappearance 
of so large a part of their favorite evergreen trees. They
are singing now at all hours but most freely at morning
& evening, earlier and later than most other birds. I
enjoy their songs exceedingly & am inclined to rate
them higher than any other Thrush music except that
of the Hermit. There is a peculiar rich, guttural, rolling
quality to their voices. Besides the song I hear the
tr-cha-a-a-a call (which I cannot certainly distinguish
from that of the Veery they are so closely similar) the 
peenk or pink and a high-pitched, rather woodeny piping
note given at short regular intervals and not so very
unlike the peeping of a Hyla but less clear & musical.
This last-named call is seldom given except at morning & evening.
