Can birds all colours or do they see only black and white?

Answers:
Yes, they can actually see more than we can! They can see infrared and ultraviolet light! (science nerd and saw it in scientific american a while ago)

i dont know im not a bird, why?

I would guess that they can see it color, as this would help them find food %26 mates. Also, many birds are colored brilliantly, so color is obviously important in their world.

Birds would not be colored so vibrantly if they could not see it! The whole point of males being so colorful is to attract a female. Some birds use color to find food...hummingbirds use their color vision to find flowers to drink nectar from.

Yes they can see colors, some birds prefer one color to another for pellets AND for toys.
I have watched my guys pick out one color and leave others or throw them to the dogs to play with.
Rico will also react and try to bite when you have brightly colored nails but if you have natural or a soft pink he could care less!

Birds see in color, this is why the males are more brightly colored than the females, to attract a mate, and the female is usually more of a dull color, because they stay at the nest and do most of the setting on the eggs!

Birds can see color and ultraviolent light. When we see blue jays, we see a blue bird. However, when a female blue jay comes along and looks at him, she doesn't see the same color bird we see. This is because not only can birds see UV light, but their feathers also reflect it. People think that seeing in color would help the females pick out a mate, but the real important thing is them seeing UV light. All male birds have a little difference in the intensity of the UV light their feathers reflect. The ones that are more flashy looking to the females will get the mates first. So even when we see a group of male jays that we think look identical, to the females, they're all different colors (or different shades, but you get what I mean).
