THE BIRDS
VIRGINIA RAIL. Rallus virginianus Linnaeus
Field characters.Size of
Robin or Killdeer; body very narrow (compressed); bill slender, over
1-1/4 inches long; tail very short, upstanding; breast cinnamon colored,
back streaked with olive brown and black. Walks with jerking movement of
head and neck.
Occurrence.Resident in
small numbers in marshy situations. Noted at Smith Creek, Snelling, and
Lagrange. Lives secluded, in streamside or pond-margin thickets, rarely
venturing into the open.
Only the observer who can take time to search
thoroughly the dense vegetation of the marshlands will be at all likely
to see the Virgina Rail. Even if present plentifully, the bird is so
elusive that a clear view of one is obtained only by chance. At
Lagrange, on December 10, 1915, a small rail was heard and seen, and the
next day a Virginia Rail was caught in a steel trap. At Snelling, on
January 9, 1915, a bird of this species was caught in an oat-baited
mouse trap placed in a marshy situation close to the Merced River. The
stealthy, mouse-like habits of the bird are indicated by these captures,
which, as far as bait was concerned, were in all probability purely
accidental. The Virginia Rail's food consists almost entirely of small
invertebrate animals, in search of which it slips through the narrow
passageways in swamp vegetation. The mouse trap had been set in such a
natural runway.
Mr. Donald D. McLean (1916, p. 229) records the
finding of a nest of the Virginia Rail, at Smith Creek, east of
Coulterville, on June 5, 1916. The structure was tower-like, composed of
grasses from the surrounding wet meadow, and was 8 inches in diameter
and about the same in height. The 10 brown-and-lilac-spotted eggs were
just beginning to be incubated.
The grass clump in which the nest was situated was
not disturbed when the meadow was mowed. When anyone approached the
vicinity, the incubating bird would slip off quietly; sometimes she
could be heard splashing through the water as she ran away. Usually she
did not go more than six feet from the nest, and there would remain
standing quietly, appearing merely as a dark shadow. She uttered
occasionally a low clucking sound.
Nothing was seen of the male until June 18, when a
shrill whistle came from him as he stood some distance away in the
grass. This was answered by a similar but softer note from his mate. The
male showed himself momentarily as he skulked through the grass, trying
apparently to distract attention from the nest.
On June 19 there were 6 coal-black young in the nest.
They had black-ringed, pink bills and their feet were large in
proportion to their bodies. The female now overcame her shyness and
walked out into the open within three feet of the observers. She fluffed
up her feathers in the manner of a brooding hen, and uttered many clucks
and whistles which were answered by the louder notes of the male.
Later the same day the nest was again visited. The
female was absent, but soon appeared, after her mate had whistled,
swimming and wading toward the nest across a bit of open water. By the
evening of the nineteenth, another egg had hatched, and by the morning
of the twentieth, 2 more; the last egg hatched that afternoon. On the
morning of June 21, the family had departed. Nothing more was seen of
them, save for one that showed itself for a moment one day in late
July.
One bird, chiefly in the blackish juvenal plumage,
was taken at the same locality, July 24, 1920.
