I was surprised to find this in the net today. Usually they are somewhere about laughing and teasing me & flying nowhere near the net! In fact, earlier on, I had shouted out to one such Green Woodpecker and suggested it should get in the efin net!
Above: My first of this species but hopefully not the last!
Above & below: From the front & back. When they fly away from you, there is a flash of yellow (like the flash of blue you see in kingfishers).
