Article summary

The White Stork which bred in Belgium in 1972 seemed to have participated in the normal migration through eastern France. This breeding case is not considered as a compensatory phenomenon to the rarefaction of the White Stork in Alsace (France), nor as a range extension, but as the re-occupation of an old breeding zone. Toponymic arguments show that the species did breed formely in this zone, in places showing the ecological characteristics of potential breeding sites. Moreover, the White Stork is represented on the coat of arms of the city of Arlon (Belgian Luxembourg). Discussing the probable causes of the White Stork's disappearance in Western Europe, it is suggested that the causes are not inherent to the White Stork, but connected to a global perturbation of the ecosystem the bird is living in. Different cases of sporadic nidification cited in the litterature are interpreted as reflecting a potential breeding zone for the species. A recent breeding record of the White Stork in the Manche (France), very similar to the Belgian case, is described. Different hypotheses are discussed, such as the existence of recent changes in feeding habits leading to the present feeding eclectism of the White Stork, and as the existence of a preferential Atlantic migration route. A general attitude is defined, in order to favourise the return of the White Stork in Luxembourg.
