Mongo, I am far from being a color expert, but I have a lot of practice figuring out how my eyes are misleading me. To me, the bird's eye clearly looks green when isolated. When the bright green reflections on the water are included, it looks sort of blue to me at first, and later I see the green. Just my 2 cents, I fear I may be disagreeing with people I have enormous respect for. You probably want to listen carefully to what they say.
Excellent shot BTW.
Also, ACR said that the blue and green levels are very close to being the same, with the blue very slightly higher.
