The autumn migration of birds, mainly Passerines, has been described on the basis of data collected by observation and catching at several localities on the Polish Baltic coast during 1961-1970. The intensity and dynamics of the passage, as well as the average andextreme dates of passage, have been presented for each locality separately. Reversed migration has been taken into account. For rare species the dates of all occurrences are given.
