Larus fuscus fuscus 1cy (juvenile) CHR5 August 08 2002, Tampere, Finland (61.33N 24.59E).

A juvenile fuscus by early August, ringed in Finland CHR5. Hand when ringed: 220 mm.
On average, juvenile fuscus is slightly more contrasting and 'cold' patterned in the upper-parts (as this individual shows) than western taxa. This bird has the fringes of the scapulars slightly buffish but rather fresh. Note the lower upper scapular region containing three very fresh feathers, probably already second generation feathers.

CHR5, ringed as pullus at Kanala (61.41N 24.06E). Other birds, ringed at the same location, are CHR2 and CHR6, both present at Tampere in autumn 2002 as well. CHR5 has only been recorded on August 08 2002 and wasn't seen again at Tampere dump despite daily visits, and may have started migration from then on.
