Résumé :
|
The Common Crane was a rare wintering bird in The Camargue until the late 1990s and early 2000s. From the winter of 2003- 2004, wintering numbers have steadily increased to more than 14,000 individuals by January 2017, spread over a dozen roosts. The frequented roosts are large open areas, usually made up of freshwater marshes. During the winter season, cranes mainly feed on rice stubble. Other food resources such as winter wheat are used to a lesser extent. Some birds do not hesitate to fly further up to 30 km to fetch food. Fifty ringed birds were controlled between 2013 and 2017, the majority (89 %) of them originated from Finland. It seems that the cranes use two migration routes to The Camargue : one central European routeway and another one possibly passing through western France, which could indicate a loop migration.
