Are crows black?In ancient China, there was a difference between black and black. Crows were not purely black. Under the sun, they would show a blue-purple or blue-green metallic luster. The color of their feathers would also change according to the angle of observation. In the eyes of birds, crows were colorful. However, there was no clear indication that crows were black, so it was impossible to determine whether crows were black or not.

Black, black crows, right?This statement was not completely correct. Although crows usually appeared black to humans, crows were not purely black. Under a specific angle of sunlight, the black feathers of common small-beaked crows, large-beaked crows, bald crows, ravens, and other species would appear blue-purple or blue-green with a metallic luster. Moreover, due to the special structure of the human eye, it was impossible to see the true color of the crow's feathers. In the eyes of birds, the crow's feathers were colorful, just like the gorgeous appearance of a peacock.

There is no exceptionThe meaning of "not necessarily so" was often placed at the end of interrogative sentences, implying that it was not so. It can also mean that something happened by chance, by accident, or by accident. It is used to describe things or situations that were not consciously arranged or planned, but happened naturally. For example, when describing interpersonal relationships such as father-son, mother-daughter, husband and wife, and friends, the word was used to indicate that some commonalities or phenomena in these relationships were natural. Or when describing the result of an event, such as a student unexpectedly getting a high score, it meant that the result was not an inevitable result.

Why are crows black?There were two main reasons why crows had black feathers. One was that crows, as animals that often ate rotten food, could absorb the heat of sunlight through their black feathers to increase their body temperature, thereby killing the bacteria and parasites on their bodies. Many scavengers had dark fur. The second reason was that crows liked to move at night. Their black feathers allowed them to hide better in the dark and avoid being discovered by hunting animals or natural enemies, thus surviving in nature.
There was also a saying that from the perspective of the story, crows once had colorful feathers, but because of their arrogance, they provoked the fire and threw themselves into the fire. Their beautiful feathers were burned, and the new feathers became black. In addition, there was also a view that the crow's dark appearance was because the human eye structure could not see its original color, and other colors could be seen when sunlight reflected the oil on its surface.

Prove that crows are blackIn fact, crows were not black. Common species such as small-mouthed crows, large-mouthed crows, bald crows, and ravens would appear blue-purple or blue-green with a metallic luster under a certain angle of sunlight. Moreover, humans could not see the colors of crows because of their special eyeball structure. In the eyes of birds, the feathers of crows were colorful, as gorgeous as peacocks. Therefore, it could not prove that crows were black.
