Great effort Andy, although a pity about the poor sound...shows folks the real truth about grouse moors though... Peckerhead and Avery will hate it!! :)
If you can physically see a golden eagle then you should easily be able to photograph it, especially with a lens like that. Although the video or photograph won't be good quality, we would still be able to clearly see it's a golden eagle.
Did they not get a tour of the snare traps then? Lets not beat about the bush here - the traps are there for the protection of the grouse alone, any 'rare bird' protection is purely incidental.
