Range.--Western North America, migrating between the Mississippi Valley
and the Rockies; breeds from northern United States north to Alaska;
winters in the south.

This sub-species is said to be very slightly larger, darker on the back,
and paler below. Their nesting habits and eggs are identical with those
of the last.

676. LOUISIANA WATER-THRUSH. _Seiurus motacilla._

Range.--Eastern United States, breeding from the Gulf, north to southern
New England, Ontario and Minnesota; winters south of our borders.

This species is similar to the last but is larger, grayer and less
distinctly streaked on the underparts. They nest in swampy places,
concealing their home in nooks among roots of trees or under overhanging
banks, the nest being made of leaves, moss, mud, grasses, etc., making a
bulky structure. The eggs, which are laid in May and number from four to
six, are white, spotted and blotched with chestnut and neutral tints.
Size .76 x .62.

677. KENTUCKY WARBLER. _Oporornis formosus._

Range.--Eastern United States, breeding from the Gulf to New York and
Michigan; winters south of the United States to South America.

Crown and ear coverts black, underparts and line over eye yellow; no
white in the plumage. These birds are found in about such localities as
are frequented by Oven-birds, but with a preference for woods which are
low and damp. They are locally common in some of the southern and
central states. They are active gleaners of the underbrush, keeping well
within the depths of tangled thickets. Like the Maryland Yellow-throat,
which has similar habits to those of this bird, they are quite
inquisitive and frequently come close to you to investigate or to scold.
They nest on the ground in open woods or on shrubby hillsides, making
large structures, of leaves and strips of bark, lined with grasses. The
eggs are white, sprinkled with dots or spots of reddish brown and gray.
Size .70 x .55. Data.--Greene Co., Pa., May 26, 1894. 4 eggs. Nest a
mass of leaves, lined with rootlets, placed on the ground at the base of
a small elm sprout in underbrush on a hillside.

678. Connecticut Warbler.--_Oporonis agilis._

Range.--Eastern United States; known to breed only in Manitoba and
