An adult female, ringed at Maasvlakte as pullus at the nest, July 10 1996. Now in 5th summer (6cy) plumage.
The elegant impression suggest a female. Note there is still a little hint of limited black visible at the bill.
Also note the difference in appearance between the pose with and without elongated neck and the head feathers raised or not.
And note the very fresh primaries. (And the rain drops on the back).

Ringed in July 1996, EM79 was recorded further north the same year, at IJmuiden, September 07 1996.

Another ringed LBBG was present April 10 2001: EM86. EM86 was ringed as pullus at the Maasvlakte, the same day as EM79, July 10 1996.
