The price of bird's nest depends on its grade and origin. The price of most bird's nests in the market ranges from $6,000 to $10,000 per catty.

First of all, the type of bird's nest is an important factor that affects its price. There are many types of bird's nests, from low-grade to high-grade, and the price gradually rises. Generally speaking, the price of common bird's nests ranges from several hundred dollars to several thousand dollars per catty, while some high-grade and precious bird's nests cost more.

Secondly, the origin of the bird's nest will also affect its price. The quality, taste and price of bird's nests from different origins vary. For example, Cave Swallows from Thailand and Javanese Cave Swallows from Indonesia are very famous places of origin, and the quality of bird's nests from these places are higher, and the price is also relatively higher.

Additionally, the freshness and dryness of the bird's nest will also affect its price. Fresh bird's nests have a better taste and are more expensive. The drier the bird's nest, the better the quality and the higher the price.

In addition, market supply and demand is also an important factor that affects the price of bird's nest. If the market demand is high and the supply is low, then the price will rise accordingly. On the contrary, if the supply is greater than the demand, the price will drop accordingly.

Overall, the price of bird's nest is a relatively subjective concept as different people have different perceptions and evaluations on the quality, taste and value of bird's nest. Therefore, when purchasing bird's nests, it is advisable to choose a product that suits your needs and budget, and purchase from reliable sources to ensure its quality and safety.
