In 851 experiments in Busse’s cages carried out at Cernek  Ringing Station (N Turkey) in autumn 2002 we studied directional preferences of 10 species of passerines. We proved high similarity of the preferred direction for almost all species – 8 of them chose the direction of ca 290' (SW) and out of these 5 showed an additional direction – 230' (NW). Based on that fact we discuss the possible interpretation of results which are found in Busse’s cages and we formulate a new hypothesis considering navigation of passerines during their first autumn migration to wintering grounds.
