Shot at Callum Brae this morning. I picked out this shot because it made me laugh, but the laugh soon went away when I thought I had a green cast on my photo. As it turns out, there is no green cast because the white feathers on the shoulder are neutral R245, G245, B245. That means something else is responsible for the green-looking crest. If it were a reflection off the green leaves, the same green reflection would be on the white feathers, but not so. The only other answer is this cocky has a green crest.
