Anser anser - Greylag Goose
This Greylag Goose was ringed on June 10, 2010 near Rijnsaterwoude, The Netherlands (52.11.34 N 04.39.50 E). I observed this bird also on February 20, 2011 in the Boterhuispolder, Warmond (no photo). Subsequently, I saw it on March 12, 2011 and on April 18 and 20, 2011 in the Klaas Hennepoelpolder in Warmond, The Netherlands.
