Moorhens and coots are common birds on ponds, lakes, rivers and canals, but which is which? There are actually a number of differences, but the most obvious is that the bill of a moorhen is red and that of a coot is white!
Appearance
The moorhen (Gallinula
chloropus) is a member of the rallidae family of birds that includes rails and
crakes, so, although it is often found in the company of ducks, it does not
have the webbed feet of a duck. It is about 33 centimetres long (13 inches)
with dark brown upperparts and dark grey underparts, with a white stripe along
the flanks and white under the tail. The legs, which have long toes, are
yellowy-green and the red bill has a yellow tip. Males and females look very
similar.
Behaviour
The moorhen
spends most of its time on the ground or the water, with flying being something
of an effort. In flight, which is usually only for a short time, the legs
dangle or trail behind. Moorhens will paddle along the surface of the water
before taking off.
The moorhen
is happiest when swimming, jerking its head and tail as it does so. It only
dives occasionally, but can, if danger threatens, stay submerged with only its
beak above the surface.
On land, it
walks with a jaunty stride except when running for cover with head down and
wings flapping.
Breeding and
feeding
Moorhens nest
in waterside vegetation, with both partners building the nest from dry reeds or
similar material. Moorhens are not gregarious birds, and will defend their nest
fiercely.
The clutch is
normally six to eight eggs, which both birds incubate for up to 22 days. The
chicks are fed in the nest for a few days, after which they swim around, not
venturing far from safety, still being fed by their parents on food consisting
of insects, larvae, spiders, molluscs and some plant material. This is similar
to the adult diet, which also includes worms, grass, seeds and a wider variety
of water plants.
Moorhens may
have as many as three broods during the year, the first in April or May, the
second in June or July and the third in August. Mortality among the chicks can
be high, with threats from all directions, including birds of prey, foxes and
other predatory mammals, and pike.
