In the 19th century, the long-legged buzzard (Buteo rufinus) was present in the Balkans as a nesting bird species only in Greece. The 20th century debuted with an enlargement of its area toward north, to reach Hungary, south-west Romania, south Ukraine and up to the border with Kazakhstan at the beginning of 2013. Our observations come from south-west Romania, where we first found the species nesting, in Oltenia. This paper presents the history of this bird distribution in south-east Europe and its expansion in Romania. New nesting points are added to complete information and distribution maps of the species Buteo rufinus. Our observations were carried out between January 2017 and September 2018, in Mehedinți County, the administrative area South-West - Oltenia, with a mosaic of habitats: crops, pastures, forests, and uncultivated areas. Inventorying and monitoring the species took place in 15 locations of the county. Nesting was monitored with a camera with motion sensor and data collecting regarding young development and other ethological aspects will be researched in the future.
