// Swainson's Thrushes are quite as numerous in the woods Swaindon's

bordering the southern end of the lake as they were when I first knew
it, dispite the disappearance of so large a part of their favorite
evergreen trees. They are singing now at all hours but most freely
at morning and evening, earlier and later than most other birds. I en-
joy their songs exceedingly, and 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 h
hear the te-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 wooden, piping note, given at short regular inter-
vals and not so very unlike the peeping of a Hyla, but less clear and
musical. The last-named call is seldom given except at morning and
evening.

I am having a fine opportunity here to study and compare Songs of.
the song of th Hermit, the Swainson's and the Wilson's Thrushes. The the Hermit
Swainson's is much the more persistent singer of the three, being Swaindon's
often heard at all hours of the day when the other two species are and Wilson's
nearly always silent save at morning and evening. Slowly but surely Thrushes
I am coming to the conclusion that the Swainson's is the finest song- Compared.
