Yellow-legged Gull michahellis 4CY 893H March 18 2013, Jakuševec landfill, Zagreb, Croatia. Picture: ringing team Luka Jurinovic.

Ringed michahellis from Croatia, orange codes with "H" may be used for winter trapping on Jakuševec landfill near Zagreb, hence no provenance on origin or exact age.

Orange 893H, ringed on March 18 2013 at Jakuševec landfill, Zagreb, Croatia. Adult looking bird, but when the wing is spread, obvious immature markings in primary coverts and GC, but also on rectrices and secondaries. Note much black on bill.
Aged by inner primaries, which are adult-like grey, lacking dark markings and adult-like P5, in combination with P10 which already shows a mirror.
