Edible bird's nests are bird nests that are prepared and eaten by humans, particularly prized in Chinese culture due to their rarity and supposedly exquisite flavor. They are among the most expensive animal products consumed by humans, with an average nest selling for $2,500 (US) per kilogramme for end-consumers in Asia.[1] The nests have been used in Chinese cooking for over 400 years, most often as bird's nest soup.[2]


The Chinese name for edible bird's nest, yàn wō (燕窝), translates literally as "swallow's (or swift's) nest", and often serves as a synonym for bird's nest soup. However, yàn wō strictly speaking is the uncooked nest.[citation needed]

Culinary use[edit]

The most famous use of edible birds nest is bird's nest soup, a delicacy[3] in Chinese cuisine. When dissolved in water, the birds' nests have a gelatinous texture used for soup or sweet tong sui. It is mostly referred to as "yan wo" unless references are made to the savoury or sweet soup in Chinese cuisine. According to the Qing Dynasty manual of gastronomy, the Suiyuan shidan, bird nest was a delicate ingredient that must not be flavoured or cooked with anything strong tasting or oily. As well, while it is incredibly precious, it must be also be served in relatively large quantities otherwise its texture cannot be fully experienced and enjoyed.[4]

In addition to its use in soup, edible birds nest can be used as an ingredient in many other dishes, it can be cooked with rice to produce bird's nest congee or bird's nest boiled rice, or it can be added to egg tarts and other desserts. A bird's nest jelly can be made by placing the bird's nest in a ceramic container with minimal water and sugar (or salt) and double steamed. Ready to eat bird's nest jelly is available in jars as a commercial product.


The most heavily harvested nests are from the Edible-nest Swiftlet or White-nest Swiftlet (Aerodramus fuciphagus) and the Black-nest Swiftlet (Aerodramus maximus).[5] The white nests and the red nests are supposedly rich in nutrients, which are traditionally believed to provide health benefits, such as aiding digestion, raising libido, improving the voice, alleviating asthma, improving focus, and an overall benefit to the immune system.[2]

Most nests are built during the breeding season by the male swiftlet over a period of 35 days. They take the shape of a shallow cup stuck to the cave wall. The nests are composed of interwoven strands of salivary laminae cement. Both nests have high levels of calcium, iron, potassium, and magnesium.[3]

Natural Bird's Nest in Thai Bird's Nest Island.

Hong Kong and the United States are the largest importers of these nests.[6] In Hong Kong, a bowl of bird's nest soup would cost US$30 to US$100.[2][6] A kilogram of white nest can cost up to US$2,000, and a kilogram of red nests can cost up to US$10,000. The white nests are commonly treated with a red pigment, but methods have been developed to determine an adulterated nest. Natural red cave nests are often only found in limestone caves in a bird nest concession island in Thailand.[3] The high cost and demand has attracted counterfeiters, leading to the halt of Malaysian nest exports to China; the Malaysian government has undertaken to employ RFID technology to thwart counterfeiting by micro-chipping nests with details about harvesting, packaging and transport.[7] Industrial quality-control techniques such as Failure Mode and Effects Analysis have been applied to Edible bird's nest processing at nesting houses in Sarawak, Malaysia.[8] [9]

The nests were formerly harvested from caves, principally the enormous limestone caves at Gomantong and Niah in Borneo. With the escalation in demand these sources have been supplanted since the late 1990s by purpose-built nesting houses, usually reinforced concrete structures following the design of the Southeast Asian shop-house ("rumah toko"/"ruko").[10] These nesting houses are normally found in urban areas near the sea, since the birds have a propensity to flock in such places. This has become an extraordinary industry, mainly based on a series of towns in the Indonesian Province of North Sumatra, which have been completely transformed by the activity. From there the nests are mostly exported to the markets in Hong Kong, which has become the centre of the world trade, though most of the final consumers are from mainland China. It has been estimated[citation needed] that the products now account for 0.5% of the Indonesian GDP, equivalent to about a quarter of the country's fishing industry. The entire global industry is an estimated $5 billion.[11]

Import restrictions[edit]

Because the bird's nest is an animal product, it is subject to strict import restrictions in some countries, particularly with regard to avian flu. Import of bird's nests to Australia is strictly prohibited. In Canada commercially prepared, canned and sterile bird's nest preparations are generally acceptable but may be subject to restrictions.[12]
