It's all in the Cones

I noticed this smart looking Herring Gull on the beach this afternoon. From a distance in the strange light that you get when the sun pokes between clouds and it is raining the legs looked quite yellowish.

When it flow up and landed near me they were suddenly obviously pink. As I've said before my colour vision is poor, but that's normally red-green, Daltonism, (also known as deuteranopia or deuteranomaly, caused by a reduced pigments in the cones in the retina). I don't usually have too much trouble with yellow, in this case I think it was the evening light.

While I was in the bay Nigel, the host at the Coastguards was putting up a new sign. I rather liked the idea of a Puffin sitting on one of the boats in the bay, but I doubt if I'll be there to see it.

On the other side of the sign there is a different image. At first I thought it was a Coastguard playing cricket with a rather strange bat, then the penny dropped and I realised it was the beam of the torch.

As I left there was a faint Rainbow over the water, but the sun wasn't strong enough to produce a really bright show.

On the way home I was amused to see this Pheasant running across a field. The wind from behind kept blowing its tail up in the air, and it kept stopped and looking back, as if it was trying to work out what was happening.
