Active migration of raptors in mid-November over Burgas area

It is usually considered that the migration of the soaring raptors lulls around the end of October. Unusually active migration of raptors, however, was observed on 15.11.2015 over Sarafovo estate of Burgas. For little more than three hours (between 11.35 and 14.45 local time) in total 1054 common buzzards (Buteo buteo) passed in south-western direction, together with 6 sparrowhawks (Accipiter nisus), 4 marsh harriers (Circus aeruginosus), 1 white-tailed sea eagle (Haliaeetus albicilla), 1 long-legged buzzard (Buteo rufinus) and even 1 lesser spotted eagle (Aquila pomarina).
Migrating raptors were observed over Burgas area and Poda Protected Site also during the days before and after the date in question, which shows that the migration of the birds of prey continues quite actively after the end of October, too. It is possible this to be connected with the unusually warm (about 20˚ С), dry and windless weather and with the weather to the north of Bulgaria as well. Obviously the known up to the moment numbers of the migrating raptors per season reflects just part of the real numbers of the migrants. Taking into consideration also the width of the migration flyway, the known to the moment figures can appear quite lower than the actual ones.
