Edible bird's nest comes from Southeast Asia, where it is built by swiftlets - chiefly the edible-nest swiftlet - from strands of their own hardened saliva. The main producing regions are Indonesia, which is by far the largest source, followed by Malaysia, Vietnam, and Thailand, with smaller volumes from the Philippines. Nests form in two very different settings: natural sea caves and purpose-built "swiftlet houses." Where a nest is gathered, and in which environment, shapes its appearance, cleanliness, and price.
Key takeaways
- Bird's nest is made by swiftlets from their own hardened saliva, not from twigs, leaves, or plant material.
- Almost all supply originates in Southeast Asia; Indonesia is the largest producing country, ahead of Malaysia, Vietnam, and Thailand.
- The two nest environments are natural sea caves ("cave nests") and purpose-built swiftlet houses ("house nests").
- Region and environment influence colour, strand tightness, cleanliness, and grade.
- TLY sources by grade, so each label reflects a consistent shape, colour, and cleanliness.
What is bird's nest, and which bird makes it?
Edible bird's nest is the cupped nest of small swiftlets native to Southeast Asia, most importantly the edible-nest (or white-nest) swiftlet. Instead of gathering twigs, these birds secrete fine threads of saliva from glands under the tongue. The saliva hardens in the air into a shallow, half-cup shape of tightly woven strands anchored to a wall or ceiling. Once carefully cleaned and dried, that structure is the raw bird's nest that reaches buyers.
Where does bird's nest come from? The main producing regions
Indonesia
Indonesia is the world's largest producer, accounting for the majority of global supply. Production is concentrated across islands such as Sumatra, Java, and Kalimantan (Borneo).
Malaysia
Malaysia is the next major source and is long associated with both Bornean cave sites and a large modern swiftlet-house industry.
Vietnam and Thailand
Vietnam is known for coastal and island nests along its central and southern shores, while Thailand contributes steady volumes from its southern coastal provinces.
The Philippines and beyond
The Philippines produces smaller quantities, rounding out a supply map that is almost entirely Southeast Asian.
Why Southeast Asia?
Swiftlets thrive in warm, humid, coastal tropics. The region's steady heat, high humidity, and abundant flying insects give the birds year-round conditions to feed and build. Limestone coastlines lined with sea caves, together with dense human settlement near the coast, provide both the natural cliffs and the man-made buildings that swiftlets will colonise.
Cave nests vs. house nests
Cave nests form on the walls of natural sea caves and limestone caverns. They are harvested by hand, often from height, and can carry more natural mineral colour and a firmer texture. House nests form inside purpose-built swiftlet houses - concrete or timber buildings, usually near the coast, that play recorded swiftlet calls to attract wild birds which come and go freely. Because the interior is more sheltered, house nests are often cleaner and more uniform in shape.
How region and environment affect grade and price
Colour, strand tightness, cup shape, and how much cleaning a nest needs all vary by origin and setting. Cleaner, more intact, tightly woven nests reach higher grades and prices, while nests that need heavier cleaning or have more breakage sit lower on the scale. This is why the same swiftlet species can yield a wide range of products.
How TLY sources graded nest
TLY selects nest by grade rather than by a single origin, matching each product label to a consistent standard of shape, colour, and cleanliness. You can explore the tiers across our Blue Label, Red Label, Specialty Nest, and top-tier TLY 5A collections.
Frequently asked questions
Where does most bird's nest come from?
Almost all of it comes from Southeast Asia. Indonesia is the largest producing country, followed by Malaysia, Vietnam, and Thailand, with smaller volumes from the Philippines.
What is bird's nest actually made of?
It is made from the hardened saliva of swiftlets, woven into a shallow cup. It contains no twigs, leaves, or plant material.
What is the difference between cave nests and house nests?
Cave nests form on natural sea-cave and limestone walls, while house nests form inside purpose-built swiftlet houses that attract wild birds. Cave nests often show more natural colour, and house nests are typically cleaner and more uniform.
Does origin affect the price?
Yes. Origin and nest environment influence colour, cleanliness, and strand tightness, which in turn set the grade and the price.
