Hi Martin,

So which photo are you thinking shows you the length of the outer rectrix? What exactly are you judging that from?

It would be a lot better if we could make the call on more than one, uncorrelated feature, though that may not be an option. May well be a Leaden, but I'm not sure it's that simple.

Cheers, Chris.
