ward.

The nesting habits of the northern form of the Blue-yellow-backed
Warbler are in all respects like those of the last, and like them, where
moss grown swamps are not to be found, they have been known to construct
nests of moss suspended from branches of trees, or to nest in bunches of
dead leaves. Data.--Oxford, Mass., June 7, 1895. Nest in a dead pine
swamp; made in end of hanging moss about 6 feet from the ground. Large
colony breeding.

649. SENNETT'S WARBLER. _Compsothlypis piti ayumi nigrilora._

Range.--Eastern Mexico, north to the Lower Rio Grande Valley in Texas.

This species is similar to the Parula but is more extensively yellow
below, and has black lores and ear coverts. Their habits are the same as
those of the last and their nests are generally placed in hanging moss,
and are also said to have been found hollowed out in the mistletoe which
grows on many trees in southern Texas, New Mexico and Arizona. The eggs
cannot be distinguished from those of the last.

650. CAPE MAY WARBLER. _Dendroica tigrina._

Range.--Eastern North America, breeding from northern New England and
Manitoba northward; winters south of the United States.

This beautiful Warbler is yellow below and on the rump, streaked on the
breast and sides with black; the ear coverts and sometimes the throat
are chestnut. They are very local in their distribution both during
migrations and in their breeding grounds. They nest in the outer
branches of trees, preferably conifers, making the nest of slender
twigs, rootlets, grasses, etc., lined with hair; the four or five eggs
are white, variously specked with reddish brown and lilac; size .65 x
.48.

651. OLIVE WARBLER. _Peucedramus olivaceus._

Range.--Mountains of New Mexico and Arizona southward.

This peculiar species may readily be recognized by its saffron or
orange-brown colored head and neck, with broad black bar through the
eye. They nest at high elevations in coniferous trees on the mountain
sides, placing their nests either on the horizontal boughs or forks at
the end of them. The nests are very beautiful structures made of moss,
lichens, fine rootlets and grasses and setting high on the limb like
those of the Blue-gray Gnatcatcher. The eggs are grayish white with a
bluish tinge, thickly speckled with blackish; size .64
