In the Atlantic Coast States this Warbler is found only as a fall
migrant, at times in considerable numbers. It lives on the ground in or
at the border of woods usually where there is dense undergrowth, and
would easily escape observation were it not for its sharp call-note,
_peek_, by which it may be identified. Its song, heard only on its
migrations up the Mississippi Valley and on its nesting ground, has been
described as resembling that of both the Oven-bird and Maryland
Yellow-throat. The only nest recorded was found by Ernest Seton near
Carberry, Manitoba, June 21, 1883. It was on the ground and contained 4
eggs, white with a few spots about the larger end.

The Mourning Warbler is one of the rarer Warblers which, by good
fortune, we may occasionally see toward the end of the spring migration.
It is usually found in the lower growth, being a brush and tangle
haunter of woods and clearings. Its song, which is described as clear
and ringing, is uttered frequently, often from a dead limb. The nest is
built in briars or bushes within a foot or two of the ground. The eggs,
laid in the first half of June, are white with a few brownish spots at
the larger end.

MARYLAND YELLOW-THROAT

_Geothlypis trichas trichas. Case 8, Figs. 50, 51_

The gray-bordered, black mask of the male makes
him unmistakable. The female is without
distinctive markings, but may easily be identified
by her notes and actions. L. 5-1/4.

_Range._ Nests from Virginia and the lower
Mississippi Valley northward; winters from North
Carolina to Florida.
