Geoffrey,
Thanks for posting these. A curious thing is shown
from Geoffrey's photos. The one on the right shows the clear grey oval below the
bird's eye. This was one of the first things I noticed about its plumage
pattern. The books vary in showing this (and many other characters). However
that grey spot seems to appear and disappear as the viewing angle changes. I
think that maybe the feather tips are dark, but bases may be grey, so when seen
along the feathers, the grey oval really shows, otherwise it doesn't. Compare
left and right photos. I wonder if this is worth formally writing up.
