Gulls in NW Europe
(last update: September 25, 2011
Herring Gull (argenteus) NLA 5.424.828 4CY, October 31 2011, IJmuiden, the Netherlands.
Ringed at IJmuiden, 06 February 2009, released after taken into hospital. It's in 4cy by 2011.
Something must have gone wrong, as the form states this bird was >4CY when released in 2009 (maybe my mistake in reading the code).
