Anser anser - Greylag Goose
The goose was marked on June 6, 2010 in Zoetermeer (52.03.28 N, 04.26.52 E), approximately 12 km south-west of Leiderdorp (52.08.57 N, 04.32.16 E). This solitary bird appeared weakened. However, it survived and I saw it again on July 2, 2011 at the Starrevaart Plas, Leidschendam, apparently in good health.
