Have you tried ebay Karen? Just found this but there are many others
'The DVD Guide To British Birds (5 DVD BO X SET)'
Thanks, Wendy - but is it the one with the right voiceover, I wonder... are there different editions of the same thing? Confused...
You have the opportunity to contact the seller & ask!
I see that the Amazon ones are already Version 9 ... obviously being constantly updated!
Aha - I've just looked on Youtube and found out it's Dave Gosney's voice!! One step closer..
Thanks, all - I'll try contacting the sellers. i thought it was an RSPB production, which is why I was asking here...
