Bird's nest is made up of saliva and substances secreted by specific species of swallows, such as swiftlets, white-haired swiftlets, etc., when they build nests during the breeding season. These swallows build nests in burrows, buildings, or other sheltered and safe places, combining saliva and substances to form bird's nests. The main production areas of bird's nest are Southeast Asian countries such as Indonesia, Malaysia, Thailand and Vietnam, among others.

These families have a natural environment and breeding conditions suitable for swallow nesting, and people regularly collect bird's nests during the local swallow breeding season.
