The most comprehensive study of bird migration in Bulgaria

Together with the Dutch Centre for Field Ornithology Sovon we realized a three-year study of bird migration, and for the first time we included the entire territory of Bulgaria. Dozens of teams counted simultaneously migrating birds in a line of observation points from Bulgaria’s western border all the way to the Black Sea coast in the east both in autumn as well as in spring. For the first time in Bulgaria we used a mobile radar for the study. Thus we provided the most complete study on bird migration in Bulgaria so far.
