Siskin, Carduelis spinus

I have been trying to photograph this female Siskin for the last month hoping that I could read the number on her ring. This is the best I have and reads, top row NH... middle LO... bottom L4... Now I just need to get shots of the other side of the ring.

 

I posted this in a thread on Winterwatch and Child of herne posted the following comment:

"Lovely photo of the Siskin. The NH and LO will refer to the contact details of Natural History Museum, London which is found on all BTO rings used in Britain. Although rings are issued by the BTO the Museum adress is used as it is better known internationally leading to better reply rates from rings recovered abroad. Unforunately I doubt that it would be possible to determine the ringing location from two digits other than it having been ringed in Britain"

 

Update 3.3.2012 I think I have managed to 'piece' together from several photographs the number, L474807.

 

This the BTO Ringing Recovery Report:

 

Ringing Scheme: London Ring Number: L474807 Species of bird: Siskin

 

 

This bird was ringed by D N Greasley as age at least 2 years, sex male on 23-Feb-2011 at Waunfawr, Caernarfon, Gwynedd

OS Map reference SH5259, co-ordinates 53deg 6min N 4deg 13min W.

It was found 375 days after it was ringed, 8 km from the ringing site, direction S.
