Gull & Tern colony under water

Lots of time till i wrote sth on the blog. I will try to be better.

As you may hear on the TV or read on the Internet, we had the flood on the May 2010 in Poland. The two bigest rivers Odra and Wisla flooded. Unlucky not even homes, buldings and fields have been waterlogged. The bigest gull and tern colony on Odra river - "Bielinek" flooded with nets, eggs and small chicks.

- about 2000 pairs of Blackheaded Gull (Larus ridibundus)
- about 200 pairs of Common Tern (Sterna hirundo)
- pair of Oystercatcher (Haematopus ostralegus) (just several breeding pairs in whole Poland)

Common Pochard (Aythya ferina) with nasal saddles in Police

On the the 20th of April 2010 Zbyszek Kajzer observed a Common Pochard (Aythya ferina) with nasal saddles C OX. The bird was obserwed with other ducks on settlers in Police Chemical Factory. There is lots of pollution like industrial sewage, biological sewage and many others... so don't know at all why birds like this place.

I"ve tried to find out some information about marked Common Pochard on the Cr-Birding... but it could be a french bird and german as well, any ideas?

Warsaw's rubbish

"Lubna" is the bigest rubbish dump in Poland and one of the most interesting, becouse of the location. You can watch there Herring gull, Caspian gull and Yellow-legged gull as well. Every year Lubna is wintering area of 1-2 Glaucous gull (Larus hyperboreus).

After draw to Euro 2012 in Warsaw we know the groups. I wonder if any football fan and bird watcher in one who will come to Warsaw to the Euro cup, visit also the Lubna :)

Last Michal's sights from the dump:

The coot C60 in Netherlands

We've recived next information about the coot with white neckband C60. On the 1st of January 2010 was in Germany (Bremen) and after 26 days was observed in Netherlands (Groningen). Nearly 300 km in 26 days it isn't long way but if you look at the map, you can easily see that the whole way is a stright line.

Thanks Rob Koelman, Klaas van Dijk and Ana Buren to report.

Nice pictures of colour-ringed Greenfinches

The Greenfinch CR project is growing. Actually we ringed a few thousands birds so it's not a fortune that also photographs meet our birds. The great exaple is Marcin Perkowski (see his website), who regularly meet ringed Greenfinches and shoot them.
