Scientists say Turkeys can see in color. Then why do they say that my dogs can't see in color.?

Answer 1

i dont think it really matters what they can see. dogs are attracted to smell more than anything. they smell something good and go after it, doesnt matter what color it is or what it looks like. and who cares about turkeys. the only thing they need to see is the blade before it cuts their head off.

Answer 2

Yes dogs ARE color blind, they see in two colors instead of three exactly the same as some color blind people. The difference between a dogs eyes and ours is that a dog has fewer cones (collect color) and more rods (collect light) so a dog sees colors about like a color blind person, and sees at night about like a person using night vision goggles.

We see "VIBGYOR" (Violet, Indigo, Blue, Green, Yellow, Orange, Red)
dogs see "VIBYYYR" (Violet, Indigo, Blue, Yellow, Yellow, Yellow, and Red). The colors Green, Yellow, and Orange all look alike to dogs

Answer 3

The shortest answer to your question is that all species of creatures have different vision capabilities. One animal being able to see colors doesn't mean that they all can.

What's interesting is that for many many years it was rumored that dogs couldn't see colors, but no one knew for sure (even though they may not admit that).

Then, in the late 1980s, a definitive set of experiments was done at the University of California to test this. I'll try not to bore you with the details, but the expirements showed that dogs do see color, but in a more limited range than that seen by normal humans.

Humans see the rainbow of colors described by "VIBGYOR": Violet, Indigo, Blue, Green, Yellow, Orange, and Red (plus hundreds of variations on these shades). Dogs, on the other hand see "VIBYYYR" (Violet, Indigo, Blue, Yellow, Yellow, Yellow, and Red). The colors Green, Yellow, and Orange all look alike to dogs; but look different from Red and different from the various Blues and Purples. Dogs are very good at telling different shades of VIB apart. Finally, Blue-Green looks White to dogs.

I'll give you the simplest explanation for these differences in color vision, but I'll warn you that it gets a bit confusing. The retinas of normal humans have three (3) types of color receptors, called "cones". Each cone type is particularly sensitive to light of a narrow limit within the entire VIBGYOR range. That means that three different "cone lines" of communication run back to the visual part of the brain, which then compares the weight of the signals coming in from each of cone "line". Different weights produce a perception of different colors. In dogs (and in "green-blind" humans), there are only two (2) types of cones, so there is less basis for comparison by the brain, and thus the perceived color range is more limited.

What this basically means, is that dog color vision is "color-limited", not "color-blind".

As for the turkeys, they are different in that they have a much wider range of vision. They can see for about 270 degrees and have good color vision.

Some side information, in case you're wondering, is that turkeys have what is known as monocular vision, which means both eyes don’t focus on the same point at the same time as occurs with humans and many predators.

A bird like a turkey is much more likely to swivel and bob its head to one side to peer at an object with just one eye. This is because each eye is looking at a different visual field, rather than working together to focus on just one object. While animals with monocular vision sacrifice certain depth and quality of vision, they gain the advantage of a much wider range of vision.

I hope this is helpful to you.

Answer 4

They used to say dogs and cats could only see grays but now they say that they see most colors. I think the reds are not as strong.

Answer 5

the main function of the dog's eyes is to notice minimal movement, especially in dim light, & then to concentrate on it intently.
lateral vision is more important than color, hence their angle of vision is wider (250- 290 degree).human's eye view is 210 degree.
dogs can distinguish between yellow & blue, but they see prodominantly in shades of grey.

Answer 6

Yes, dogs can see some colors. Our trainer has us use "touch targets" with yellow and blue on them, as dogs can see these colors. It's not as bright and vibrant as we see them, but they can see them still.

Answer 7

Upon examination of eyeballs they determined that many animals don't have "cones". Cones differentiate the colors we see. All sighted animals have "rods",just as we do. Rods see light and dark,as well as shades of gray in between. :-)=

Answer 8

The eyes of different animals have different structures. In particular some animals have both rods and cones in their retina. The cones allow the eye to see in colour.

Answer 9

because your dog is not a turkey i guess...

Answer 10

hi hey can see
