THE COMMON GALLINULE. [Common Moorhen.] |
Genus | GALLINULA CHLOROPUS, Linn. [Gallinula chloropus.] |
The two species of Gallinule which occur in the
United States are confined within a comparatively small range in that extensive country, the southern
portions of which appear to suit them better, at all seasons of the year, than
the other districts. The Common Gallinule is extremely abundant during winter
along the rivers, fresh-water creeks, lagoons, ponds and lakes between the Gulf
of Mexico and the eastern shores of the Floridas, while in spring and summer a
good number migrate eastward into the Carolinas, and now and then a few
stragglers may be seen on the fresh waters of the Middle Districts, beyond which
none, to my knowledge, have ever been observed. They seldom ascend any of our
southern streams to any considerable distance, few are ever met with many miles
above Natchez on the Mississippi, and none are to be seen in the Western
Country.
In general they are equally diurnal and nocturnal in their habits, and when
undisturbed frequent the land as much as the water. In the lower parts of
Louisiana and the Floridas, I have seen them seek their food and amuse
themselves by day in the pastures and fields, and I have observed both them and
the Gallinules of England enacting their courtship, while the sun was yet high
above the horizon. In sight of man, however, they are timorous, although not
shy, and retreat from him among the grass and sedges bordering the water, to
which they resort for safety. If shot at, or otherwise frightened, they run
with speed, and either fly or swim off as fast as possible, to elude their
enemy.
During my various temporary residences in London, I have often seen the
Gallinules resort to the grounds in the Regent's Park at all hours of the day.
They were there in a manner partially domesticated, and walked quite
unconcernedly in the meadows, led their young over the water, and paid their
addresses to each other, while fifty or more persons were amusing themselves
with feeding the ducks and swans over the bridge leading to the inner circle,
and within sight of these birds. While I was at Spring Garden Springs in East
Florida, in the early part of January, the Gallinules were seen in great numbers
on every bayou leading towards the waters of the St. John, and at that early
period the manifestations of their amatory propensity were quite remarkable.
The male birds courted the females, both on the land and on the water; they
frequently spread out their tail like a fan, and moved round each other,
emitting a murmuring sound for some seconds. The female would afterwards walk
to the water's edge, stand in the water up to her breast, and receive the
caresses of the male, who immediately after would strut on the water before her,
jerking with rapidity his spread tail for awhile, after which they would both
resume their ordinary occupations. This was in the middle of the day, when I
could have counted eight or ten pairs in sight.
The nest is formed with more labour than art, being composed of a quantity
of withered rushes and plants, interwoven in a circular form, frequently from
two to three inches thick in the centre, surrounded by an edge or brim four or
five inches high. If not greatly disturbed, these birds raise several broods in
a season, using the same nest, and making additions to it previous to depositing
each new set of eggs. In Lower Louisiana I found it usually five or six feet
from the water, among the rankest weeds, along the bayous and lakes, which are
so numerous there. In some instances it was placed on a prostrate trunk of a
tree over the water, when the materials of which it was composed were less
abundant than in other circumstances. I never saw one floating loose, but have
often heard people say they had occasionally seen a nest in that state, although
I am not much disposed to give credit to such assertions. The number of eggs
seldom exceeds eight or nine, and is more frequently from five to seven. As the
bird lays more than once, its progeny is thus numerous. The Gallinules cover
their eggs when they leave them, no doubt to protect them from Crows and other
enemies, but return to them as soon as food has been procured, although both
sexes incubate. The eggs measure an inch and five-eighths, by an inch and one
and a half eighths, and are of a dull darkish cream colour, spotted and dotted
with various tints of reddish-brown and umber.
The females are as assiduous in their attentions to their young as the Wild
Turkey Hens; and, although the young take to the water as soon as hatched, the
mother frequently calls them ashore, when she nurses and dries them under her
body and wings. In this manner she looks after them until they are nearly a
month old, when she abandons them and begins to breed again. The young, which
are covered with hairy, shining, black down, swim beautifully, jerking their
heads forward at each movement of their feet. They seem to grow surprisingly
fast, and at the age of six or seven weeks are strong, active, and perhaps as
well able to elude their enemies as the old birds are. Their food consists of
grasses, seeds, water-insects, worms, and snails, along with which they swallow
a good deal of sand or gravel. They walk and run over the broad leaves of
water-lilies as if on land, dive if necessary, and appear at times to descend
into the water in search of food, although I cannot positively assert that they
do so.
On more than one occasion, I have seen a flock of these young birds playing
on the surface of the water like Ducks, beating it with their wings, and
splashing it about in a curious manner, when their gambols would attract a
garfish, which at a single dart would seize one of them and disappear. The rest
affrighted would run as it were with inconceivable velocity on the surface of
the water, make for the shore, and there lie concealed and silent for a quarter
of an hour or so. In the streams and ponds of the Floridas, this species and
some others of similar habits, suffer greatly from alligators and turtles, as
well as from various kinds of fish, although, on account of their prolific
nature, they are yet abundant.
This Gallinule seldom resorts to salt water, but at times is met with on
the banks of bayous in which the water is brackish. This, however, happens only
during winter. On land it walks somewhat like a chicken, and thirty, forty, or
more individuals may be seen searching for worms and insects among the grass,
which they also nip in the manner of the domestic fowl. On such occasions, the
constantly repeated movements of their tail are rendered conspicuous by the pure
white of the feathers beneath it, which, along with the white stripes on the
flanks, and in spring the vivid red of the frontal plate, renders their general
appearance quite interesting. In cases of danger, they run with great speed,
and easily conceal themselves. On the water they sit very lightly, and swim
with activity, the movements of their head and neck keeping pace with those of
their feet. They pick up their food from either side, continually jerk their
tail, and not unfrequently touch the water with it.
Although not a migratory bird, this species flies very well, whenever it
has occasion to rise from the ground. Its wings, although concave, are large
for its size, more so in fact than those of Rallus crepitans, which migrates to
a considerable extent. But in general, the Gallinules are averse from flying,
unless when anxious to remove from one lake or stream to another, when they rise
fifty or sixty feet in the air, and fly with ease and considerable velocity, by
continued flappings, the neck and legs stretched out. At all other times when
raised, they suffer their legs to dangle, proceed slowly to a short distance,
and drop among the reeds, or, if over the water, they dive and hide, leaving
nothing but the bill projecting above the surface.
The young in autumn have not attained their full size; their colours are
much duller than those of the old birds, particularly the stripes on the flasks
and under the tail, which are of a dull cream colour instead of being pure
white. The frontal plate is small, and almost covered by the feathers around
it; the legs and feet are of a dingy green, and the red band on the tibia is
scarcely apparent. In spring they acquire their full plumage, but the frontal
plate increases in size for several years.
There are great differences as to size between birds of both sexes. The
male from which I drew the figure in the plate, was of an average size, having
been selected from a bagful procured expressly for the purpose.

The female is similar to the male, but has the frontal plate smaller.
The young, when fledged, have the upper part of the head of an
olivaceous-brown, like the back and wings, the neck of a light dull grey, the
chin dull white, the lower parts light grey, tinged with yellowish on the
breast, most of the feathers tipped with whitish, the lines on the hypochondrial
feathers of a dull cream colour and of small extent. The frontal plate is
small, and with the bill of a dingy greenish colour, as are the feet, the claws
yellowish-brown.
On comparing together a great number of European and American specimens, I
can find no specific differences. Individuals of either kind are larger or
smaller, their frontal plates differ in size and somewhat in form, as do the
bill and the claws; but if the species are really different, Nature has made
them so wonderfully like each other, that there seems to me no possibility of
distinguishing them.
My friend Dr. NEILL has furnished me with the following anecdotes
illustrative of the habits of this bird. "At Canonmills Loch, near Edinburgh, a
pair (or sometimes two pairs) of Water-hens breed yearly, making their nest on
the branches of some very large saughs (willow-trees, Salix russeliana) growing
in my garden, and overhanging the pond. One season (four or five years ago)
finding themselves persecuted by a tame Heron, which watched and devoured their
first young brood (for we detected him in the act), they formed their nest more
than fifteen feet high on the trunk of the willow-tree. There the eggs were
hatched in safety, four or five young being in due time seen sailing about with
the old birds. We had only one pair on the Loch last summer. How they
descended to the water can only be conjectured: they might have crept downwards
three or four feet, but they must at all events have fallen at once from a
height of not less than twelve feet. When the pond is frozen over and covered
with skaters, the Water-hens enter the garden and conceal themselves in an
overgrown rock-work, subsisting on minced flesh mixed with bread or potatoes,
purposely laid down for them, and on which I have often watched them feasting
when the snow was lying deep."
