Distribution
and habitat
The lapwing
is a farmland bird that is most commonly seen in northern England and southern
and eastern Scotland. However, lapwings winter in estuaries and lowland
pastures in other parts of England, including the Somerset Levels and The Wash.
Typically, their breeding grounds are in upland areas, but there is also a
breeding population in the New Forest, which is close to the coast of southern
England. Preferred breeding sites include fields sown with early cereal and
root crops, rough pastures, meadows and undisturbed heathland.
Appearance
The lapwing
is about 32 centimetres (12-13 inches) long. At a distance, the bird appears to
have black upperparts and white underparts, but the back has a distinct
greenish sheen. The throat and chest are black and there is an orange streak
under the tail. The wings are broad with rounded, paddle-like ends, that are
flapped extravagantly in flight. However, the feature that is most distinctive
is the long wispy crest that extends from the back of the head, turning up at
the end.
Breeding
The male
lapwing performs an energetic display flight, with tumbles and dives, which he
repeats after a female has been attracted. Nest building takes place in March
or April, the nest consisting of a shallow depression in a field, lined with a
few leaves, stalks or twigs. Some birds choose a more elevated position so that
they can keep a lookout for danger.
The clutch is
usually four eggs (sometimes only three) which are incubated by both parents in
turn for up to 28 days. If a clutch is lost, the female may try again several
times, but only one brood will be raised. The chicks only stay in the nest for
a couple of days before dispersing into the nearby undergrowth for safety.
Food for
lapwings is worms, insects, larvae, spiders and molluscs, plus some vegetable
matter and seeds. The nesting area is not normally suitable for gathering food,
so the parent birds, who look after the chicks until they fledge at about five
weeks, lead them to feeding grounds that can be some distance away.
After they
leave their breeding grounds, lapwings can be seen in large flocks in
agricultural areas and coastal winter quarters.
Conservation
The lapwing
is a protected species in the United
Kingdom , being on the red list of species
under threat. In former times, lapwing eggs were a sought-after delicacy, and
an Act of Parliament was necessary (in 1926) to make the practice illegal.
However, changes in agriculture, such as the conversion of grassland to crop
growing, have also affected lapwing numbers. Modern crops grow quickly, which
may not suit the timetable of the lapwings if the stalks are too high at the
time they wish to nest.
Although
lapwing numbers have declined in areas where farming methods have seen most
change, there has been something of a revival in the New
Forest , where the ecology is far more bird-friendly and forestry
practices have produced a more suitable habitat than that of managed farmland.
The main threats here to lapwing broods are natural ones, such as crows, foxes
and the careless feet of ponies and other animals.
Overall, the
lapwing continues to be a species in danger, with only 40% (at best) of chicks
surviving to breeding age.
