What do we call the first time swiftlets make nests?

Official swallow: also known as white bird's nest, good quality, mostly artificially dehaired, smoked white with sulfur, for the first or second nest built by the general swiftlet, less hair, white and smooth or slightly yellow, the smell is fragrant, the sac is thick with mesh, the water is soft and expanded, the water of the top grade is high, it can expand more than 10 times after absorbing water and is not dissolved, even if it has been stewed, it remains the same.

Let me tell you about the varieties of bird's nest:

The first nest built by swiftlets is completely based on the gradual condensation of a large amount of mucus secreted by their throats, the texture is pure, not a single hair is attached, this kind of bird's nest is the best quality, is the best in the bird's nest. In the era of feudal dynasties, it was often selected as a tribute, so it was named "Guanyan".

After the bird's nest pickers seized the opportunity to pick the bird's nest, the swiftlet had to make a nest for the second time, because the oviposition period was closer, the swiftlet was plump, the throat gelatinous matter was more, and the nest built was relatively fat, but because of the urgency of time, they brought feathers and grass. It is mixed with the laryngeal gelatinous substance and builds a nest again, which is relatively rough, contains more impurities, and has poor nutrients. The bird's nest harvested at this time is called "Mao Bird's Nest".

Spawning was imminent, and swiftlets had to build their nests for the third time. At this time, its throat forcibly vomited blood-like mucus, some of which were bright red in color, and the nest built could be said to be painfully congealed and coagulated. At this time, the person who picks the swallow should not pick it anymore, so that the swiftlet can have children, and wait for the mother swallow to fly away from the nest with the milk swallow before picking, which is called picking "old nest", also known as picking "blood bird's nest".

There is another kind of bird's nest that is moistened by the red liquid oozing out of the red rock wall attached to it, and the whole body is dark red, also called "blood bird's nest" or "red bird's nest", which contains a number of minerals, good nutrition, and has little yield, and is regarded as a treasure in bird's nest.

The nest made by swiftlets for the first time is called white bird's nest.

Adult swiftlets lay eggs three times a year, with April, August, and December being the peak spawning seasons for swiftlets. Nesting begins about 30 days before each oviposition, each nesting is about 30 days for male and female swallows to build together, the hatching period of the eggs is about 20 days, the male and female swiftlets will be fed together after the baby swiftlets hatch, and the baby swiftlets can fly on their own to forage for food and find another perch after about 40 days, no longer use this nest, it takes 90 days from nesting to the fly away of the baby swiftlets.

Bird's nest is rich in trace elements such as calcium, phosphorus, iron, sodium and potassium. Amino acids such as: lysine, cystine, arginine. Carbohydrates, water-soluble protein and rich in bird's nest acid.

The grading classification standard of Yipin Bird's Nest Indonesia is not only the basis for consumers to buy bird's nest, but also the bird's nest rating guide for global bird's nest peers.

Palace swallow, the first knot of the nest thick and white, because the swiftlet after a long winter, there is a long time to recuperate, the body stores enough nutrients, saliva quality is better, so the nest built is better and thicker, the shape is excellent, and it is in the shape of a cup, because it is only for the palace in ancient times, so it is called the palace swallow.

The nest that knots the second time is called the bird's nest.

The nest that knots for the third time is called a blood bird's nest.
