The Hermit Thrushes can readily be identified from any other by the
reddish brown tail which is in marked contrast to the color of the back.
The nesting habits and eggs of this species are precisely like those of
the eastern Hermit Thrush, which is a sub-species of this.

759a. AUDUBON'S HERMIT THRUSH. _Hylocichla guttata auduboni._

Range.--Rocky Mountain region of the United States. Winters in Central
America.

The nesting habits of this bird are like those of the next except that
it more frequently nests in bushes above the ground. The eggs are not
distinctive.

759b. HERMIT THRUSH. _Hylocichla guttata pallasi._

Range.--Eastern North America, breeding in northern United States and
north to Labrador; winters in southern United States.

This species, which is noted for its sweet and musical song, frequents
damp swamps and thickets where it builds its nest either on the ground
or near it, like that of the Wilson Thrush; it is made of shreds of
bark, grasses, leaves and rootlets, lined with fine rootlets; the three
or four eggs, which are deposited in May or June, are bluish green and
cannot, with certainty, be distinguished from those of the Veery; size
.85 x .65.

759c. DWARF HERMIT THRUSH. _Hylocichla guttata nanus._

Range.--Pacific coast of United States, from Washington, southward.

The nesting habits and eggs of this slightly smaller and duller colored
variety are like those of the other Hermit Thrushes.

760. RED-WINGED THRUSH. _Turdus musicus._

Range.--An Old World species, accidentally straying to Greenland.

This common European bird nests at low elevations in bushes or trees,
laying four or five bluish green eggs, spotted with reddish brown; size
1.05 x .75.

761. ROBIN. _Planesticus migratorius migratorius._

Range.--North America east of the Rockies, breeding from the middle
portions of the United States, north to the Arctic Ocean.

These common birds nest in trees about houses, in orchards, open woods,
in corners of fences, on blinds on houses, and in fact almost every
conceivable position. Their nests are made of grasses, firmly cemented
together with mud and lined with finer grasses; when placed in trees
they are generally firmly saddled in crotches and may be found at any
height, from on the ground to sixt
