The history of the stork in the Zwin has had a remarkable resurgence. Storks were introduced to the area in the 1960s, marking the start of their return as breeding birds in Belgium. This return followed a period when storks were extinct in our country in the late 19th century. Later, storks were released in several locations in Belgium, resulting in a steady increase in the population, thanks in part to growing numbers in neighbouring countries. Today, storks once again find their home in several locations in our country, with a total of over 200 breeding pairs.

Despite being spread across several breeding sites in Belgium, the Zwin and its surroundings remain one of the most important breeding areas for these impressive birds.

The storks breeding in the Zwin are closely monitored by conservationists and researchers. The breeding success of all pairs present is closely monitored, with all young storks being fitted with a scientific ring every year. But population monitoring does not stop here. Since 2019, a transmitter project has been launched in collaboration with the Royal Belgian Institute of Natural Sciences, allowing researchers to track and understand the stork population even better.

This transmitter project aims to better understand the storks’ living habits, such as their migratory behaviour, foraging areas and breeding site preferences. Advanced technology allows researchers to track the movements of individual birds in real time. This information is invaluable for population conservation and management, as well as for understanding the wider ecological processes within the Zwin.

Besides the scientific importance of the transmitter project, it also contributes to raising awareness about the importance of conservation. By sharing the data and stories of individual storks tracked through the transmitters, people can develop a deeper understanding of the challenges faced by these iconic birds. It also provides opportunities for education and ecotourism, giving visitors to the Zwin the chance to follow the birds and learn more about their fascinating way of life.

In short, the stork is not only a symbol of fertility and happiness, but also an extraordinary ambassador for biodiversity conservation in the Zwin. Thanks to dedicated efforts by conservationists and researchers, and innovative projects such as the transmitter project, we can continue to enjoy the grace and beauty of these extraordinary birds in their natural habitat.
