Migration of herring gulls

I and collaborators are examining the migration of herring gulls winter in Japan using data loggers (geolocator) and numbered plastic rings (white colored).  The objective is to understand their migration routes and movement patterns as well as their spring destinations.  We would like to understand the adaptability of migration of herring gulls.  We appreciate any infomation on gulls marked with leg rings.
