Formation of bird's nest
The bird's nest is a kind of bird called "Jin Siyan". It uses moss, seaweed and soft plants to mix their feathers and saliva, and cement the bird's nest as a hiding place. People take this bird's nest down, and after refining and selecting it, it becomes a valuable bird's nest.
Jin Siyan nests three times a year, and the first nest is thick and white. Because Jin Siyan has a long winter, a long rest time, enough nutrients are stored in the body, and the quality of saliva is better, so the nest built is better and thicker, shaped like a lamp, hence the name Zhan Yan, which is the best in bird's nest.
There is a kind of bird's nest called "Blood Swallow", which is built by a kind of "brown-tailed Jin Siyan". This swallow may drink different water quality, or it may be because of minerals and other factors, its saliva is red, so it has built a "blood swallow" nest. The other is called Bai Yan, which is mostly produced in Indonesia, and the other is called Mao Yan, which is mostly produced in Brunei and Borneo.
