My most far east record so far (2600 km) of a Black-headed gull.

Ringed in ESTONIA as a nestling on June 14th 1991 and recaptured and ringed with a second (!) ring in POLAND on March 17th 1995. In the following years he is seen quite often in February-March in Amsterdam THE NETHERLANDS. On March 18th 2006 he is captured again in the Oosterpark in Amsterdam where gets a colour ring. He has lost the aluminum Matsalu ring !!! In subsequent years the colour ring is read regularly. Most likely, he breeds in ESTONIA and the migrates through FRANCE towards ENGLAND where he overwinters every year. And in spring he migrates trough THE NETHERLANDS and LATVIA to his breeding site in ESTONIA.
In total, this Black-Headed Gull has been observed in 6 different countries. A record for my colour ring research !
