Article summary

After several failed attempts in the last few years in Flanders and in the Harchies Marshes, the Great White Egret Casmerodius albus finally succeeded to breed in Belgium for the first time in spring 2012. This first successful breeding pairs was found in the clay pits of Ploegsteert, a very important wetlands in Western Belgium. This event followed a spectacular increase of the Great White Egret, both as migrant and wintering species, and more recently as a bird present throughout the summer in Wallonia (Southern Belgium). The evolution of its status in Belgium is to be placed in the context of a rapid increase of the European range of this heron, from the last third of the 20th Century. Remarquably, one of the adults of Ploegsteert was ringed in 2003 as a chick in the colony of Grand-Lieu Lake (Loire Atlantique, France).
