=======================================================
Odd Phylloscopus
trochilus,
collybita, trochilus x collybita?
The bird was
caught the 9 September 2006 at 12:10 in a net group consisting of 3 nets
at Vargviken on Fårön in Piteå, Sweden (65º 20.263'
N 21º 31.109' E).
The weather was fine with hard NV winds and approx. +14° C.
The colour of
the tarsi did not match anything
I ring regularly and the emargination on the sixth primary
made me confused.
