Adult-looking 4cy Lesser Black-backed Gull

Langvannet, 24.05.2013

Same as above

Ringed as young in 2010 in southern Norway.

Herring Gull J2877

P8 hidden behind P9. 26.02.2011

Same bird 2 years later. 30.03.2013

This bird is interesting. Note how the marking on both P9 and P5 evolves. P9 shows a window 2 years later, and P5 shows extensive black markings. Sadly not a bird with known age.
