MISSOURI MEADOW-LARK.
[Western Meadowlark.]
STURNELLA NEGLECTA, Aud.
[Sturnella neglecta.]
PLATE
CCCCLXXXIX.--MALE.
Although the existence of this species was known
to the celebrated explorers of the west, LEWIS and
CLARK, during their memorable journey across the
Rocky Mountains and to the Pacific; no one has since
taken the least notice of it.
These travellers mention
it at page 236 of the first volume, edited by PAUL
ALLEN, Esq., and revised by ARCHIBALD M'VICAR.
They say, on the 21st June, 1805, "There
is also a species of Lark, much resembling the bird
called the Old Field Lark, with a yellow breast and
a black spot on the croup. * * * * The beak, too,
is somewhat larger and more curved, and the notes
differ considerably." The expedition was, at the
period mentioned, in the neighbourhood of the great
Falls of the Missouri.
We found this species quite abundant on our voyage
up the Missouri, above Fort Croghan, and its curious
notes were first noticed by Mr. J. G. BELL, without
which in all probability it would have been mistaken
for our common species (Sturnella Ludoviciana). When
I first saw them, they were among a number of Yellow-headed
Troupials, and their notes so much resembled the
cries of these birds, that I took them for the notes
of the Troupial, and paid no farther attention to
them, until I found some of them by themselves, when
I was struck with the difference actually existing
between the two nearly allied species.
In their fight, manners on the ground, and general
habits, nothing different from S. Ludoviciana could
be observed; but on comparing the Missouri Meadow
Lark with specimens of S. Ludoviciana, procured near
New York, the differences are quite sufficient to
warrant me to describe the former as a new and hitherto
undescribed species. The bill of the Missouri Meadow
Lark is more curved, and considerably narrower, than
in the common species, indeed it in scarcely more
than one half the breadth of the bill of the latter.
The Missouri Lark is also considerably smaller, but
the greatest difference is in the form of the tail,
which in this species is nearly square, and consequently
has the feathers nearly equal, whilst in the common
one, the tail is rounded, and the two lateral feathers
are nearly three quarters of an inch shorter than
the middle ones; besides which, the central tail-feathers
of the present bird are narrowly barred, and not
scalloped on their margins as in Sturnella Ludoviciana.
The nest in not covered over, and the eggs are considerably
smaller, and differently marked. This species is
very shy, but abundant on all the prairies; its flesh
resembles that of the common bird, and is indifferent
eating.
MISSOURI MEADOW-LARK, Sturnella neglecta, Aud. 10,
16.
Upper Missouri. Abundant.
Adult Male
The male measures 10
inches from the point of the bill to the end of the
tail, to end of claws 11 1/4; alar extent 16; wing
from flexure 4 7/8; tail 3. Third quill longest.
Bill along the ridge 1 and nearly 3/8, along the
edge 1 3/8; tarsus 1 5/8; middle toe 1, its claw
3/8; hind toe 5/8, its claw 1/2.
The eggs, which are usually four or five in number,
measure 1 1/8 inches in length, by 3/4 in breadth,
pure white ground. The spots are more bold, larger,
and of a brighter reddish colour than those of S.
Ludoviciana, and are diffused over the whole surface,
instead of being crowded toward the larger end, as
is the case in the common species. The irides are
brownish, and the hairs on the upper eye-lid longer
and more numerous. The general colours and markings
are much the same in both species, but much paler
in the present one.
