The difference between blood bird's nest and white bird's nest

1. The difference in color

The most direct difference between blood bird's nest and white bird's nest is the color. The color of white bird's nest is generally white, while the color of blood bird's nest is red, as bright red as blood, so it is called blood bird's nest. Some people say that the color of blood bird's nest is caused by the blood vomited by the swallow. In fact, this statement is not true. It is just a gimmick created by merchants to sell blood bird's nest.

There are many theories about why the blood bird's nest turns blood red. One theory is that the swallow vomited blood, while another theory is that the bird's nest was built on a red rock wall and was soaked in red liquid. In fact, this theory is not true. The blood bird's nest may be a nest built by a swallow called the brown-tailed swiftlet, which turned blood red due to the influence of the environment.

2. Different effects

White bird's nest can whiten the skin, replenish blood and regulate menstruation, and is a very suitable nourishing food for women. The price of blood bird's nest is more expensive. Many people think that the reason why this kind of bird's nest is more expensive is because it contains a lot of iron. In fact, these are not true. The effect of blood bird's nest is not as high as that of white bird's nest.

3. Different location

White bird's nests are usually picked from eaves or in the forest, while red bird's nests are usually picked from caves. According to people who have climbed the Bird's Nest Mountain, the deeper you go into the Bird's Nest Cave, the darker the color of the bird's nest becomes. The bird's nest near the cave entrance is usually white, while the bird's nest inside is orange-red.
