, yellowish underparts,
and an ashy gray head, neck and breast; they have a complete whitish
ring about the eye, this distinguishing them in any plumage from the two
following species. As they do most of their feeding upon the ground and
remain in the depths of the thickets, they are rarely seen unless
attention is drawn to them. They are quite abundant in New England in
fall migrations, being found in swampy thickets. They have been found
breeding in Ontario by Wm. L. Kells, the nest being on the ground in the
woods among raspberry vines. It was made of leaves, bark fibres, grass,
rootlets and hair. The eggs are white, specked with brown and neutral
tints. Size .75 x .55.

679. MOURNING WARBLER. _Oporornis philadelphia_.

Range.--Eastern United States, breeding from northern New England,
Pennsylvania, (Philadelphia) and Nebraska northward.

Very similar to the last but with no eye ring and a black patch on the
breast. The habits and nesting habits of this species are very similar
to those of _agilis_, the nest being on or very close to the ground.
With the exception of on mountain ranges it breeds chiefly north of our
borders. The eggs are white, specked with reddish brown. Size .72 x .55.
They cannot be distinguished from those of the last. Data.--Listowell,
Ontario, June 5, 1898. Nest in a tuft of swamp grass in low ground; not
very neatly made of dry leaves, grasses and hair. Collector, Wm. L.
Kells. (Crandall collection.)

680. MACGILLIVRAY WARBLER. _Oporornis tolmiei._

Range.--Western United States from the Rockies to the Pacific, breeding
north to British Columbia; winters in Mexico and Central America.

Similar to the last but with white spots on the upper and lower eyelids,
black lores, and the black patch on the breast mixed with gray. These
ground inhabiting birds are found in tangled thickets and shrubbery
where they nest at low elevations, from one to five feet from the
ground. Their nests are made of grasses and shreds of bark, lined with
hair and finer grasses, and the eggs are white, specked, spotted and
blotched with shades of brown and neutral tints; size .72 x .52.
Data.--Sonoma, Cal., May 17, 1897. A small nest, loosely made of grasses
(wild oats) lined with finer grasses; placed in blackberry vines 14
inches from the ground in a slough in
