Spotted-breasted thrushes are typically slightly smaller than robins. Their dark eyes, shorter tails, and spotted breasts distinguish them from thrashers. They prefer the forest understory; eat insects and berries. All are fine singers. (From Golden Books A Guide to Field Identification: Birds of North America).
The wood thrush is the common nesting thrush in eastern deciduous forest and suburbs. It has an olive body but a rusty head and the spotted breast all thrushes have.
The thrush alone declares the immortal wealth and vigor that is in the forest.
Whenever a man hears it, he is young, and Nature is in her spring.
Wherever he hears it, it is a new world and a free country, and the gates of heaven
are not shut against him. - Henry David Thoreau
