A successful habitat reconstruction effort, the short history of the European Bee-eater (Merops apiaster) colony at Albertirsa (Hungary)

In the Golyófogó Valley near Albertirsa natural erosion created near vertical walls in the loess deposited in the last glacial period, offering natural nesting sites for the European Bee-eater. Later the deeply cut coach roads, the pits of loess extraction and the construction works of the motorway nearby created further man-made banks. Hence by the 1970-ies a well-established colony bred here, but by the beginning of the 21^st century, disturbance and the demise of vertical banks led to a serious reduction in the number of breeding pairs. The purchase of 5-hectare loess grassland plot and the adjacent loess bank, and later its reconstruction led to an unprecedented growth in the number of Bee-eaters. From 2010 the number of breeding pairs exceeded 200 every year. Not only the Bee-eater colony, but also the natural vegetation and the botanical values of the area are managed to maintain the population of rare and protected element of the local flora and fauna.
