| Summary: | To document the migration pattern of the black-headed gull in Bavaria 706 recoveries were used from the EURING-databank. The material supports previous results, that gulls borne in the southern part of Bavaria (south of the river Danube) use south-western areas for wintering (> 85% of all recoveries), whereas gulls from northern Bavaria use areas in north-western (about 40%) and south-western direction (60%). In general no pronounced influence of the population increase was found during the sixties on the spatial migration pattern. Weak evidence points to some temporal changes in the migration pattern: gulls migrate a bit earlier to the breeding areas. Since 1965 an increased colony fidelity has occured. |
