Thanks Marmot and Luke,
We have gone down the "official lines", but I was hoping that someone might recognise the ring sequence etc as originating from a specific country.
Just have to wait and see I guess.
Reading The Migration Atlas the Stromness Hawfinch is in quite a select group. There have only been two foreign rung Hawfinches ever recorded in Britain.One ringed on the Czech border of Germany 27 March 1962 was on Shetland 7 May 1967, and probably more relevant, a male ringed in southernmost Norway on 11 October 1990 was found dead on Fair Isle on 10 April 1994.
Fascinating.
Cheers,
Paul
