Everything about The White Stork totally explained
The
White Stork (
Ciconia ciconia) is a large wading
bird in the
stork family
Ciconiidae, breeding in the warmer parts of
Europe (north to
Estonia), northwest
Africa, and southwest
Asia (east to southern
Kazakhstan). It is a strong
migrant, wintering mainly in tropical
Africa, down to the south of
South Africa, and also in the
Indian subcontinent.
It is a huge bird, 100-125 cm (40-50 in.) tall, with a 155-200 cm (61-79 in) wingspan and a weight of 2.3-4.5 kg (5-10 lbs). It is completely white except for the black wing flight
feathers, and its red bill and legs, which are black on juveniles. It walks slowly and steadily on the ground. Like all storks, it flies with its neck outstretched.
There are two
subspecies (
HBW):
- Ciconia ciconia ciconia Linnaeus, 1758. Europe, northwest Africa, westernmost Asia; wintering in Africa.
- Ciconia ciconia asiatica Severtsov, 1873. West-central Asia; wintering in India.
The
Oriental White Stork (
Ciconia boyciana), now regarded as a distinct species, was formerly treated as a subspecies of the White Stork.
Conservation and population
Notable breeding totals occur mainly in central and eastern Europe, with 52,500 pairs in
Poland (6th International Census of White Stork, 2004), 12,000-18,000 pairs in
Ukraine, 10,500-13,000 pairs in
Belarus, 10,000 pairs in
Lithuania, the highest known density of this species in the world, and 8,500 pairs in
Latvia. In
Germany, 3,000 of the total 3,400 pairs are in the former
East Germany. In southwestern Asia,
Turkey has the highest population, with 15,000-35,000 pairs. Apart from
Spain (14,000 pairs) and
Portugal (1,000-2,000 pairs), numbers in western Europe are much less healthy, with the once sizable
Danish population declining to just five pairs in 1995, while re-introductions of zoo-reared birds have halted declines in
Italy (30 pairs), the
Netherlands (9-12 pairs), and
Switzerland (120-160 pairs). A few pairs also breed in
South Africa, recent colonists from within the normal wintering population (
HBW). North of the breeding range, it's a rare passage migrant or vagrant in
Finland,
Great Britain,
Iceland,
Ireland,
Norway, and
Sweden, and also west to the
Azores and
Madeira. Data (except Poland and South Africa): Snow & Perrins 1998.
Threats to the species include the drainage of wetlands and other agricultural intensification, collisions with overhead power lines, use of persistent
pesticides (such as
DDT) to combat
locusts in Africa, and (largely illegal) hunting on passage and the wintering grounds (
HBW). Some birds, known in German as
Pfeilstorch ("arrow storks"), have been found in Europe with African
arrows embedded in their bodies.
The White Stork is one of the species to which the
Agreement on the Conservation of African-Eurasian Migratory Waterbirds (
AEWA) applies.
Behaviour
White Storks rely on movement between thermals of hot air for long distance flight, taking great advantage of them during annual migrations between
Europe and
Sub-Saharan Africa. The shortest route south would take them over the
Mediterranean, but since thermals only form over land, storks take a detour. The options are limited, because to the east lies the
Arabian Desert, where it's difficult to find food and water - and to the west lies the
Atlantic Ocean. This leaves two narrow migration corridors: eastern storks cross the straits of
Bosporus to
Turkey, traverse the
Levant (
Syria-
Lebanon-
Israel-
Palestine), and then bypass the
Sahara Desert by following the
Nile, while western ones fly through the straits of
Gibraltar. Either way, the storks can get help from the thermals for almost the entire trip and thus save energy .
White storks breed in open farmland areas with access to marshy wetlands, building a stick nest in trees, on buildings, or special platforms. Because it's viewed as bird of good luck, it isn't persecuted, and often nests close to human habitation. In southern Europe, storks' nests can be seen on
churches and other buildings. It often forms small colonies. Like most of its relatives, it feeds mainly on
frogs and large
insects, but also young birds,
lizards and
rodents.
The white stork is almost silent except for the noisy mutual bill-clattering when adults meet at the nest.
Cultural associations
According to mythology, the 'stork' is responsible for bringing babies to new parents. This story probably came about because White Storks have a habit of nesting on buildings in urban areas, so they're often seen around human habitation.
Poles, Lithuanians and Ukrainians believe that storks bring harmony to a family on whose property they nest. The White Stork is the national bird of
Poland and
Lithuania. Famous polish poet
Cyprian Kamil Norwid mentioned polish storks in his poem "My song":
Ukraine it's called as
buziok. There it's associated with the start of a new
family in a new
home. In Ukraine the bird is considered as the
Messenger of Spring, because it's one of the first birds to return to the
Ukraine after
wintering. It is also - set against a yellow and green background - the symbol of the city of
The Hague,
The Netherlands.
