We eat bird's nests but rarely learn about the birds that make them. Understanding a little about swiftlets helps you see why the bird's nest farming industry is very different from other agricultural sectors, and why the environment is so important. This article summarizes the basic characteristics widely described in literature about the group of swiftlets that produce edible nests; details vary according to species and region, and the article does not provide specific unverified data.

Appearance and flight

Swifts are small birds, with long and narrow wings, slender bodies, flying fast and agilely in the air. They spend most of the daytime in the air hunting for food and rarely perch on branches like many other birds. Their small legs are more suited for clinging to walls than perching on tree branches.

What do they eat and how do they forage?

Swifts eat small insects flying in the air and catch them while flying. Therefore, areas with many insects (fields, rivers and streams, forests, orchards) are usually suitable for swift colonies. This also explains why using a lot of pesticides around swift houses can affect their food source; see sustainable swift farming.

Living in colonies and returning to the nest

Swifts live in colonies, usually flying out to feed during the day and returning to their nests in the evening. They choose places that are dark, cool, humid, and quiet to build their nests; in nature, these are caves and cliffs, and in swift farming, these are bird houses designed appropriately.

Echolocation

Many species of swifts that nest in dark caves use short, repetitive calls; the echoes help them identify obstacles while flying in the darkness, similar to echolocation. This is why sound is mentioned in swiftlet attraction techniques, see technology in swiftlet farming.

Nesting and reproduction

During the breeding season, swiftlets use saliva to build nests. They usually lay a few eggs per clutch (often described as very few), incubate, and raise the chicks. The cycle and number of clutches vary according to the flock and conditions, see swiftlet nest harvesting season. The nests used as food are primarily this dried saliva.

Why is it necessary to protect swiftlets?

  • They are a part of the ecosystem, participating in the insect food chain.
  • Illegal exploitation and destruction of nesting caves reduce the population; see Government bans the hunting of swiftlets.
  • Legal swiftlet farming means luring the flock to a farm, not hunting.

What does this have to do with customers buying bird's nests?

Understanding swiftlets helps you ask reasonable questions to the seller: which swiftlet house the birds come from, what kind of environment they are raised in, and whether regulations are followed. See the swiftlet farming regions and island bird's nest and Mainland bird's nest (swiftlet house).

Frequently Asked Questions

Are swiftlets swiftlets?

The two names are easily confused in daily life, but they belong to different bird groups according to classification; swiftlets for edible nests have specific characteristics as mentioned.

Do swiftlets depend on people for survival?

No; the birds fly and forage in nature on their own, the swiftlet farm only provides a suitable nesting place.
