Many thanks for all the comments so far.
I'll just quickly summarise the background to my query. In late November, a
Hoopoe was found dead in Durham, UK and is now stored at the Discovery
Museum in Newcastle, UK. To my eyes, the dark colouration of the orange on
the bird suggests it may belong to the subspecies saturata (which originates
from Asia), as opposed to the subspecies epops (which originates from
Europe). As concluded by Ericson, a key difference between these subspecies
is the colouration of the orange. A photo of the bird can be found here:

If it is possible to produce equivalent results as Ericson, this would help
in deciding which subspecies the bird belongs to (and therefore whether it
may have originated from Asia or Europe).
So could anybody provide a step-by-step method, which would produce results
comparable with those of Ericson, for photographing the bird (my camera is a
Canon 40D) and analysing the photos in Image J (or any other program)?
Robert Dougherty in particular hinted that this may be possible.
Thanks again
Ross

If you can *see* the differences between the birds with your eyes in
pictures taken with a camera that takes RGB images, I think, it should be
possible. Maybe you need some sort of "standard curve" / reference data sets
created by visual assertion of birds to groups.
Actually this might be a good job for a neuronal network.
Have fun
