Who’s ever been on the Dutch motorways to drive on, the picture will be well aware of: at the top of a high lamp-post, sit, black-and-white bodies with long thin legs. Often, in couples or in small groups. A normal picture is in the summer. However, it is considered by some to be the winter, and they are still there. Is it not about time that the storks return to Africa?
Indeed, the white stork is a migratory bird. Some of the birds are gelegenheidstrekkers. Such as greylag geese, which are dependent on the weather conditions, relatively short distances, and flying back and forth to the winter, free from the grip of a hard frost to keep up.
But the storks are of real inter-continental day-trippers. They breed in Europe, and after a bountiful summer on the strength of his come, and they leave at the end of August for the long trip. They fly in through Gibraltar, the Mediterranean Sea and the Sahara desert to tropical Africa. The white stork in Eastern Europe, sometimes even all the way to South Africa. This is our winter, and the birds have a lot of food. In February, the first of the white stork along the same route back to their nests.
there is, however, a number of you that missed the bus, can be any observant bird watcher will tell you. Across the country, are still sightings of the white stork has been reported. In Meppel,, Drenthe, on 30 december, 2019 at the latest, even for a group of one hundred and one units were spotted.

the Increase in wintering white stork is due to the recovery after the DDT crisis,
as You would expect it to be as a result of climate change, according to marine biologists, there is something else going on here. Anyway, it continues to be a part of the stork is always left behind. The increase, which men can see in the last few winters (and summers), is the result of something else: the restoration of an ecological crisis due to the use of the now-banned landbouwgif DDT. The white stork and many birds of prey such as common buzzards climbing, being in the country again in the direction of natural numbers at the beginning of the twenty-first century.
DDT is a powerful insecticide. Because it is highly effective found in pest control in the agricultural sector, was the person who discovered it in 1948, and the Nobel prize in Chemistry. But it turned out to be the subsequent food chain from the lever, and the onafbreekbaarheid to accumulate in large predators. So, TRACE now even being found in polar bears at the north Pole and penguins in the Antarctic. It was in the mid-seventies in dangerous concentrations have been detected in human breast milk.
By the publication of Silent Spring in 1962, American biologist Rachel Carson was turned upside down for the public as a whole. In the Netherlands, the use of DDT in 1973 and is strictly prohibited. In many of these countries, however, it is still being used a lot.
more than One in five storks to stick to it in the winter
as for The restoration of the white stork, and after the ban on DDT, however, for a long time. At the end of the sixties, was the white stork in the Netherlands, is almost extinct, and in 1990 it counted, our country is only ten breeding pairs. Now breed in the Netherlands, according to the Society, as a total of 1,100 pairs of white stork, to which the population will be fully restored to the level of more than a hundred years ago.
The research for the white stork in the Netherlands, a STORK, organizes every year a special wintertelling. Therefore, they try to map out how much of the white stork: well actually, in our country, to remain during the winter. In the census of January 2019 547-wintering of white storks have been reported. According to STORK, the older white storks, who no longer have to be in for the long ride. The young of the storks go in winter, just almost all the way to Africa.
Wageningen, the biologist Arnold van Vliet, sums up the simple phrase: “The winter of the white stork is a common sight. You see, because there’s more of it.” According to Van Vliet, is it going to be about one-fifth of the Dutch population, and in the winter will also be affected by a successful captive breeding program, which is a part of the white storks around the broedcentra to settle down.
you can Also vogelorganisatie Sovon, to do research on the white stork. They say that the stork came out of a breeding program, to an increasing degree of wild behaviour, and it is also about the wider areas of distribution, including the wintertrek to Africa. Moreover, to keep the white stork, not from the cold. In the event of snow and ice in the winter, therefore, in accordance with Sovon, the tendency of protection is to look at cities in the Netherlands.
