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).

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.
