Range. - Pacific coast, breeding in Oregon and Alaska; winters in Central America.

This species is very abundant in moist thickets throughout its range, nesting in bushes and low trees, and making them of weed stalks, bark strips, grasses and moss, lined with fine black rootlets. They are found an elevations of from two to ten feet above the ground. Like the Wood Thrush the birds are tame while sitting on the nest and will allow a very close approach, without taking alarm; nests are frequently found which are made almost entirely out of green moss and are very handsome structures. Their three to five eggs are laid in May or June; they are greenish blue, spotted with brown of varying shades. Size .92 x .65. Data. - E u r e k a, California, July 6, 1899. Nest in a fir tree, 5 feet from the ground; made of moss and strips of redwood bark. 4 eggs.
