How can they really tell what a chicken or dog, etc. can see?. I know they must dissect eyes and figure " oh they are missing this, so they can only see that, ." I don't buy it.

Doesn't the brain have something to say in all this?

i should have said that in my first post on this thread...
thanks!

Chickens don't see in infra red. It's the opposite end of the spectrum they see - ultraviolet. Snakes use infra red to 'see' the body heat given off by prey. So they can even hunt in complete darkness. Ultraviolet (UV) on the other hand is absorbed by some surfaces and reflected by others. Caribou use ultraviolet light to spot wolves in snow. Wolf hair absorbs UV light whereas snow reflects it. So even white wolves look very dark against the snow and can be spotted from far away. (I recently saw a documentary about animal super senses - we were all fascinated by it). In the same way this is why chickens can spot a bug we weren't even aware of because we can't see that end of the light spectrum. We only have three light detecting cones (photoreceptors) in our eyes that detect red, green and blue light and from that our brain processes all the colours we can 'see'. Seeing UV requires a fourth cone which birds possess. Flowers use ultraviolet light to attract pollinators such as insects and birds so they look quite different to an animal capable of seeing UV. It's fascinating stuff - nature is truly amazing!
