In partnership with the Romanian Ornithological Society, for more than 10 years we have been organizing this programme in Romania, which is conducted in almost all European countries. Milvus Group has a fairly large amount of work, as we gather data from 20 counties of Romania. Year by year, we collect essential data from 50-60 important wetland areas, where 100,000-160,000 birds spend the winter. The relevance of the programme is given by the fact that observations are made simultaneously with other European countries (but also around the world). Therefore, we yearly get a clear picture of the evolution of waterfowl numbers even at a European level.
