done. He does not hug the log, but stands
very erect, expands his ruff, gives two introductory blows, pauses
half a second, and then resumes, striking faster and faster till the
sound becomes a continuous, unbroken whir, the whole lasting less
than half a minute. The tips of his wings barely brush the log, so
that the sound is produced rather by the force of the blows upon the
air and upon his own body as in flying. One log will be used for
many years, though not by the same drummer. It seems to be a sort of
temple and held in great respect. The bird always approaches on
foot, and leaves it in the same quiet manner, unless rudely
disturbed. He is very cunning, though his wit is not profound. It is
difficult to approach him by stealth; you will try many times before
succeeding; but seem to pass by him in a great hurry, making all
the noise possible, and with plumage furled he stands as immovable
as a knot, allowing you a good view, and a good shot if you are a
sportsman.

Passing along one of the old Barkpeelers' roads which wander
aimlessly about, I am attracted by a singularly brilliant and
emphatic warble, proceeding from the low bushes, and quickly
suggesting the voice of the Maryland yellow-throat. Presently the
singer hops up on a dry twig, and gives me a good view: lead-colored
head and neck, becoming nearly black on the breast; clear
olive-green back, and yellow belly. From his habit of keeping near
the ground, even hopping upon it occasionally, I know him to be a
ground warbler; from his dark breast the ornithologist has added the
expletive mourning, hence the mourning ground warbler.

Of this bird both Wilson and Audubon confessed their comparative
ignorance, neither ever having seen its nest or become acquainted
with its haunts and general habits. Its song is quite striking and
novel, though its voice at once suggests the class of warblers to
which it belongs. It is very shy and wary, flying but a few feet at
a time, and studiously concealing itself from your view. I discover
but one pair here. The female has food in her beak, but carefully
avoids betraying the locality of her nest. The ground warblers all
have one notable feature,--very beautiful legs, as white and
delicate as if they had always worn silk stockings and satin
slippers. High tree warblers have dark brown or black legs and more
brilliant plumage, but less musical ability.

The chestnut-sided belongs to the latter class. He is quite common
