Are chimpanzees color blind

Answer 1

It depends what you consider colorblind, and which monkeys you're interested in. All primates have some color vision--that is, they are at least dichromatic. Dichromats can see some colors but are blind to certain distinctions, usually the difference between red and green. Some new world monkeys only have dichromatic vision. Other new world monkeys as well as all old world monkeys and apes have trichromatic vision and can make all the color distinctions that humans with normal color vision can make.

Answer 2

No. Apes and monkeys can see colors. They are the only animals, other than man, that scientists can conclusively say have color vision. They can be trained to open a colored door which has food behind it.

Answer 3

Firstly there is a need to define 'colour blind': colour blindness or colour vision deficiency is the inability or decreased ability to see color, or perceive color differences. Colour blindness is divided into the following categories: Monochromacy, Dichromacy, Anomalous trichromacy and Total color blindness. It is assumed for this question, that the OP is asking about 'total colour blindness'.

There has been disputed cases on whether macaws, and other parrots in the Psittacidae family (to which the macaw belong) are able to see colour.

It has been proven on a number of different occasions however, that birds, including the Psittacinae family are able to see into the ultraviolet spectrum of colour.

UV vision was first demonstrated by birds in the 1970s, however the knowledge, understanding and concept of colour in parrots was first documented by Irene Pepperberg in the 1980s, with the African Grey Parrot, Alex. Alex demonstrated the ability to recognise over 50 different shapes, including seven colours. While there has yet to be studies similar to the Avian Learning Experiment conducted with macaws, many owners have reported successful results with teaching their birds colour recognition. There have even been cases where macaws have had preferences and even severe dislike for certain colours!

Parrots and macaws alike use colour, in particular in the UV spectrum to help identify a likely candidate for a mate, as birds with dull plummage often suggest sickness or disease, whereas plumage that is iridescent, like the blues, reds, yellows and greens found on macaws, reflect UV light, giving strong emphasis to the term 'healthy glow'. It is claimed that birds are also able to see this UV colour difference in fruit, hence why they are able to identify which fruit is ripe. (It was originally thought that they could 'smell' the fruit, however experiments have shown that macaws have a poor sense of smell, when compared with other animals)

While macaws cannot see and identify colour the way humans can, that is in no way to suggest that they are colourblind. It would be incorrect to compare the human colour spectrum against that of a macaw, as we are able to see the same colours, but in different ways.

Answer 4

No they are not because scientists have done research on it

Answer 5

No. They can see the color of ripe fruit.

Answer 6

Their eyes are brown.

Answer 7

Yes, almost all rodents are color blind.

Answer 8

i think they do
