THE DOWNY WOODPECKER. [Downy Woodpecker (see also Gairdner's Woodpecker).] |
Genus | PICUS PUBESCENS, Linn. [Picoides pubescens.] |
The Downy Woodpecker, which is best known in all parts of the United States
by the name of Sapsucker, is perhaps not surpassed by any of its tribe in
hardiness, industry, or vivacity. If you watch its motions while in the woods,
the orchard, or the garden, you will find it ever at work. It perforates the
bark of trees with uncommon regularity and care; and, in my opinion, greatly
assists their growth and health, and renders them also more productive. Few of
the farmers, however, agree with me in this respect; but those who have had
experience in the growing of fruit-trees, and have attended to the effects
produced by the boring of this Woodpecker, will testify to the accuracy of my
statement.
This species is met with, during summer, in the depth of the forest, as
well as in the orchard or the garden. In winter it frequently visits the
wood-pile of the farmer, close to his house, or resorts to his corn-crib, where,
however, it does little damage. I have found it pretty generally distributed
from the lower parts of Louisiana to Labrador, and as far to the westward as I
have travelled. It seems, in fact, to accommodate itself to circumstances, and
to live contented anywhere.
About the middle of April it begins to form its nest, shewing little care
as to the kind of tree it selects for the purpose, although it generally chooses
a sound one, sometimes, however, taking one that is partially decayed. The pair
work together for several days before the hole is completed, sometimes perhaps a
whole week, as they dig it to the depth of a foot or sixteen inches. The
direction is sometimes perpendicularly downwards from the commencement,
sometimes transverse to the tree for four or five inches, and then longitudinal.
The hole is rendered smooth and conveniently large throughout, the entrance
being perfectly round, and just large enough to admit one bird at a time. The
eggs, commonly six in number, pure white, and translucent, are deposited on the
bare wood. In the Southern and Middle States, two broods are raised in the
season; farther north seldom more than one. The young follow their parents
through the woods, in company with Nuthatches and Creepers, and seem at all
times lively and happy. Their shrill rolling notes are heard at a considerable
distance, as well as those which they use when calling to each other. Their
food, during summer, consists of insects and their larvae; but, at the approach
of autumn, they feed on fruits of various kinds, especially small grapes, and
the berries of the poke-weed. The extensile portion of the tongue of this
species, as well as of Picus varius, P. villosus, and P. querulus, is
cylindrical or vermiform, while the extremity, or tongue itself, is linear, flat
above, convex beneath, with projecting edges which are serrated backwards, the
tip pointed.
The flight of the Downy Woodpecker, like that of the other species, is
performed by glidings and undulations, between each of which it utters a single
click note; and, although usually short, is capable, on occasion, of being
protracted. The bird is by no means shy or suspicious, and scarcely pays any
attention to man, even when standing close to the tree on which it is at work.
Towards winter many individuals migrate southward, and spend their time in the
immediate neighbourhood of the planter's dwelling.
I have observed that during their stay in the Floridas, Georgia, and the
Carolinas, their breast and belly are so soiled by the carbonaceous matter
adhering to the trees, in consequence of the burning of the grass at that
season, that one might be apt to take a specimen in that state, as belonging to
a different species.

Male, 6 3/4, 12.
Breeds from Texas to Labrador, and northward to lat. 58 degrees. Common
throughout the interior to the eastern bases of the Rocky Mountains. In every
district a constant resident.
Adult Male.
Bill longish, straight, strong, tapering, compressed, slightly truncated
and cuneate at the tip; mandibles of equal length, both nearly straight in their
dorsal outline, their sides convex; nostrils basal, oval, covered by recumbent
bristly feathers. Head of moderate size, neck of ordinary length, body robust.
Feet rather short, strong; tarsus strong, scutellate before; two toes before and
two behind, the inner hind toe shortest; claws strong, arched, very acute.
Plumage soft, with rather disunited barbs, slightly glossed; wings large,
the third and fourth quills longest; tail longish, cuneate, of ten tapering
stiff feathers, worn to a point.
Bill bluish-black; iris dark red; feet bluish-green; claws light blue,
black at the end. The top of the head is black, as are a broad band behind the
eye, another below the cheek, as well as the shoulders, wings, and tail; there
is a bright red narrow band on the occiput. A band over the eye, and meeting on
the hind neck; another from the base of the upper mandible, passing under the
eye, and down the neck; six bars on the wings, and the greater part of the
middle of the back, together with the three lateral tail-feathers on each side,
white, the latter marked with black spots. The lower parts in general are dull
white.
Length 6 3/4 inches; extent of wings 12; bill along the ridge 10/12; tarsus
3/4.
Adult Female.
In the female, the red band on the head is wanting, the place occupied by
it in the male being white. The lower parts are brownish-white.
In a male preserved in spirits, the width of the mouth is 4 1/2 twelfths,
the tongue is 8 1/2 twelfths long, its horny part 3 1/2 twelfths, slender,
tapering, flat above, furnished on the edges with a single row of rather strong
deflected bristles, about 12 in number. The hyoid bones converge on the top of
the head as usual, but do not proceed farther forward than opposite the centre
of the eye, terminating at the distance of 4 twelfths from the base of the bill,
in which respect they contrast strongly with those of the Hairy Woodpecker. The
oesophagus is 2 1/4 inches long, its width scarcely 1 twelfth, it being in its
contracted state narrower than the trachea; the proventriculus enlarges to 3
twelfths. The stomach is elliptical, 7 1/2 twelfths long, 5 1/2 twelfths in
breadth, its muscles well developed; the epithelium thin, tough, rugous, and of
a reddish-brown colour. It is filled with farinaceous vegetable substances of a
whitish colour. Intestine of moderate length, wide, 8 inches long, its width at
the upper part 2 twelfths. No coeca. Trachea 1 inch 5 twelfths long, its
breadth nearly 1 twelfth; its contractor muscles moderate; its rings about 50;
the bronchial half rings 12. The salivary glands are of large size.
THE RAMPING TRUMPET-FLOWER.
BIGNONIA CAPREOLATA.
This species is met with only in the Southern Districts. It is rather rare
in Louisiana, but abounds in Georgia, Alabama, and the Floridas. The flowers
are destitute of odour. Humming-birds delight to search for food in them, as
well as in those of other species of the genus.
