New cr-rings in Polish BHG project

We start ringing black-headed gull (Chroicocephalus ridibundus) with brand new, yellow cr-ring. Darvic ring has always 4 digits and start with "T". There is also a web page adres on it http://ring.stornit.gda.pl (to Polish POLRING system).

Darvic Black-headed Gulls migration

Every month i get a new recovery of my darvic Black-headed gulls which were ringed in the West Pomerania Province in Poland. This research become more and more interesting. Hope to write a publication about it in nearly future, but right now see these two birds.

чтить/Hello! Black-headed Gull

Not so often we receive a report of Polish-ringed bird in Russia. This is a large country with a low population density (just 8 Pop. per km2), so a chance to find ringed bird is even lower. FN77822 was also carrying the darvic ring TH08 when found in July 2010 at pond near Vozdvizhenskoe. The Gull was weak and released in dry place.


This bird had been ringed as 2cy on 15.12.2009 and covered a distance of 1419 km. Interestingly, FN77822 was cought using fishing line on my flat windowsill in Szczecin.

This is my first recovery of Black-headed Gull (Chroicocephalus ridibundus) in Russia, hope not the last :)

Croatian Black-headed Gull (Chroicocephalus ridibundus) at Miedwie Lake

Is not the first Croatian Black-headed Gull (Chroicocephalus ridibundus) who visit the Miedwie Lake (the fifth bigest lake in Poland). They really like roosting place on the north coast (Morzyczyn). Look forward to hearing from Luka about ringing details.
