Green ring with a white 4 alpha-numeric code (letter 'P' into the code)

Please report your sightings using the new POLRING platform, where you are getting an immediate access to the life histories. Please visit ring.stornit.gda.pl and register to create an account. After your account is created, you may add records of birds you resighted (by using option 'New record'). There are many fields to fill in, that define your records precisely, but in  most cases you just select one option from the predefined list. You may upload photographs accompanying the record of course. When you use the platform, it is a matter of hours (up to 2 days) to have an access to the full life-history of the bird, assuming that ringing data are in the system (they are not only if a bird was ringed very recently, the system then asks the ringer to provide data as soon as possible. This is anyway sooner than email). If you experience any problems using the system, write to:

note 1 : gulls are ringed since 2000 in central and southern Poland as either breeding adults or chicks.
note 2 : species are L. argentatus (mainly central Poland), L. cachinnans, L. michahellis (mainly southern Poland) and hybrids between these three (everywhere). One L. fuscus and two hybrids L. fuscus x L. argentatus have also been ringed.
note 3 : there are quite many hybrids, not always possible to identify in the field, so please take a digiphoto if possible.
