Uniform direction of Great Tits migrating over Europe

The Great Tit (Parus major) is considered to be a species migration of which is characterized by very variable parameters, including the direction of movements and migration flyways. I verified this thesis based on analysis of ringing recoveries from seven bird ringing stations located along eastern and southern Baltic coasts (Russia, Estonia, Lithuania, Poland) and on studies of other authors (data from Sweden, Finland, Russia, Czech Republic, Ukraine, Germany, Switzerland). I stated that all partly migratory populations of Great Tits in Europe move in a broad front along parallel lines running from north-east towards south-west, at ca 235° angle. The observed departures from this rule are usually caused by occurrence of geographical barriers (mountains, seas). The individual variation is relatively low and only 3% of birds were observed outside wintering grounds typical for their populations.
