Birds and animals develop bright colouration to attract mates,but aren't animals and birds colourblind?

Answer 1

Birds and animals are certainly not colourblind. But the amount of colur or information they are able to see varies from species to species.

Nocturnal mammals and birds have less-developed color vision. Marine Mammals can see only black and white.In herbivorous primates, color perception is essential for finding proper (mature) leaves.

Some birds, including hummingbirds, are thought to be sensitive to even ultraviolet light, since the flowers from which they drink display patterns only visible in ultraviolet light.

Answer 2

birds are not colorblind at all, if they were then they would not have the bright colors they do. Most animals are not colorblind either. Many do not see the whole color spectum like humans do, and may not see some colors as brightly, but almost all of them can differenciate between reds and greens.

Answer 3

To begin with, birds are animals. The term animal
is often incorrectly used as though it meant
mammals, which is apparently what you are doing.
There are four or five kinds of living things, -
plants, animals, fungi, bacteria and, if you want to
separate them from bacteria, archaea. Anything
alive is in one of these categories. (Viruses are
not listed because they are generally not thought
to be alive.)

Birds and mammals may or may not have color
vision. Birds mostly, perhaps all, do have. In the
mammals color vision is absent in many because
so many of them are nocturnal. Diurnal mammals
like primates normally have color vision. Many other kinds of animals also have color vision, fish
and insects, for example, though not all of them.

Answer 4

Not all are. Nonetheless those who see only gray scale are very sensitive to bright HUES. That's why a colourblind bull charges at something bright red.

Answer 5

Many _seem_ to be colorblind -- they don't react to color cues in tests -- but others have keen color vision, extending into what are for us the infrared and ultraviolet. Other species don't use bright coloration for this purpose, but distinctive calls or pheromones.

Answer 6

No they aren't colorblind. Hummingbirds, for example, are attracted to bright red feeders.

Answer 7

its ungulates who are colour blind ( hooved animals ), like cows bulls, antelopes etc.

Answer 8

Not all of them...For example humming birds.Eh?
