Hello Tweeters,

I see a lot of green color described on dorsal surface feathers in Cornell's species description.
Note that I have added a [bracket] around each time a feather group is described as [green or greenish].

Also, I think the green dorsal feathers are much more easily seen in certain light conditions and the males. They are one of my species of interest for video photography, and I have followed them for many years.
Very neat bird.
Dan
