Bird's nests, as the name suggests, are the nests of swallows, most notably the nests of swiftlets. Swiftlets spit and build their nests, and the entire nest is white, crystalline, elastic, and highly nutritious, so the bird's nest can be said to be the saliva of swallows. Nowadays, most of the bird's nests have artificially cultivated components, for example, One True Pure Bird's Nest has specialized swiftlet houses to raise swiftlets and collect their nests to make bird's nests.
