When learning about Swiftlets, many people are surprised by their distinctive behaviors and high economic value. Today, indoor swiftlet farming has become a highly profitable industry, opening up numerous opportunities for sustainable development.

In this article, we will take an in-depth look at Swiftlets, covering their biological characteristics, living habits, nesting process, and the potential of the edible bird’s nest business. This information will provide you with a comprehensive understanding of this remarkable bird species.

Introduction to Swiftlets

Swiftlets are small birds from the Apodidae family, known for their ability to fly continuously and build nests using their saliva. This species not only holds biological significance but also offers great economic benefits, especially in the edible bird’s nest industry. Understanding Swiftlets helps farmers develop effective strategies and maximize nest harvesting efficiency.

What Are Swiftlets?

Swiftlets belong to the Apodidae family, which consists of over 100 species worldwide. The most well-known is the Edible-nest Swiftlet (Aerodramus fuciphagus), renowned for producing high-value bird’s nests.

These birds are small in size, with a slender body, large wingspan, and short legs that prevent them from perching on tree branches. Unlike most birds, Swiftlets spend the majority of their lives in the air, only stopping to build nests and raise their young.

This bird species is known for its strong homing instinct and its ability to navigate using echolocation in complete darkness. This unique trait is also the reason why swiftlet farmers can construct swiftlet houses to attract and sustainably harvest bird’s nests.

Where Do Swiftlets Live?

Swiftlets are primarily found in tropical and subtropical regions, ranging from Southeast Asia and South Asia to Northern Australia. In the wild, they build nests in caves, high cliffs, and remote areas with minimal human disturbance.

In Vietnam, swiftlets are commonly found in coastal provinces such as Khánh Hòa, Bình Thuận, Phú Yên, Kiên Giang, and Cà Mau, as well as certain Central Highlands regions like Gia Lai. Thanks to the favorable climate, many areas have developed indoor swiftlet farming models, allowing for sustainable nest harvesting while maintaining suitable living conditions for these birds. Over time, swiftlets have adapted well to artificial swiftlet houses, enabling a more controlled and efficient approach to edible bird’s nest production.

What Makes Swiftlets Unique?

Swiftlets possess remarkable biological traits that set them apart from other bird species:

• They never perch: Swiftlets spend almost their entire lives in the air, only clinging to surfaces when building nests or caring for their young.
• They navigate using echolocation: They emit special calls that help them map their surroundings in complete darkness.
• They build nests entirely from saliva: Unlike other birds that use straw or leaves, swiftlets secrete a sticky substance from their salivary glands to construct their nests, making edible bird’s nests highly valuable.
• They live in large colonies: Swiftlets form massive flocks to protect themselves from predators and make food hunting more efficient.
• They are loyal to their habitat: If their environment remains favorable, they will return to the same nesting site for multiple generations.

Thanks to these unique characteristics, swiftlets are not only biologically fascinating but also hold high economic value in the edible bird’s nest industry.

Biological Characteristics and Behavior of Swiftlets

What Do Swiftlets Eat?

Swiftlets primarily feed on small airborne insects such as mosquitoes, flies, winged termites, and flying ants. They are skilled aerial hunters, using their sharp reflexes to catch prey mid-flight with remarkable precision.

The quality of their diet directly impacts the nutritional composition and color of their nests. In areas with an abundant supply of insects, swiftlets produce nests that are whiter, thicker, and richer in nutrients.

For indoor swiftlet farming, preserving natural insect populations in the surrounding environment is crucial. Ensuring an adequate food source keeps the birds healthy and allows them to produce high-quality edible bird’s nests.

How Long Can Swiftlets Fly Without Resting?

Swiftlets are among the few bird species capable of sustained flight for extended periods without perching. This remarkable ability is due to their unique body structure and evolutionary adaptations:

• Long, slender wings: Reduce air resistance, allowing swiftlets to fly efficiently with minimal energy expenditure.
• Powerful chest muscles: Well-developed pectoral muscles enable continuous wing movement for extended flight durations.
• Optimized heart and circulatory system: The swiftlet’s heart is proportionally large, ensuring efficient blood circulation to supply oxygen continuously during flight.
• Rapid digestion: Their fast metabolic rate allows them to digest food quickly, providing instant energy to sustain long, uninterrupted flights.

Research has shown that swiftlets have the ability to sleep while flying. They can engage in unihemispheric sleep, meaning one half of their brain remains active to maintain balance while the other half rests. This adaptation allows them to continue flying without perching, helping them evade natural predators such as birds of prey.

On average, swiftlets fly for 8 to 12 hours per day in search of food.

• During migration seasons or when seeking new food sources, they can fly continuously for up to 20 hours a day.
• Juvenile swiftlets, after leaving the nest, are capable of flying for several months non-stop before landing for the first time.

Thanks to their exceptional endurance, swiftlets can cover vast areas in search of food and suitable habitats. This ability also makes them highly adaptable to indoor swiftlet farming, as they can thrive in controlled environments while maintaining their natural behaviors.

How Do Swiftlets Reproduce?

Swiftlets have a stable breeding cycle, typically occurring from March to September each year, depending on environmental conditions. Some key characteristics of their reproduction cycle include:

• Lifelong monogamy: Swiftlets form a lifelong bond with a single mate, remaining faithful throughout their lives.
• Nesting before egg-laying: Swiftlets must complete their nests before laying eggs. If their environment is disturbed or the nest is removed before egg-laying, they may abandon reproduction altogether.
• Egg-laying and incubation: Each breeding cycle, a pair of swiftlets lays 1 to 2 eggs. Both parents take turns incubating the eggs for 22 to 26 days until they hatch.

In artificial farming conditions, swiftlets can reproduce 2 to 3 times per year, which is more frequent than in the wild. This accelerated breeding cycle makes indoor swiftlet farming a long-term and sustainable investment.

The Nesting Process of Swiftlets

How Do Swiftlets Build Their Nests?

Swiftlets construct their nests entirely from their saliva, a complex process that takes 30 to 35 days to complete.

• Selecting a Nesting Spot: Swiftlets choose a suitable surface for nest-building, typically rock cliffs, cave ceilings, or wooden panels in artificial swiftlet houses.
• Saliva Secretion and Layering: The birds continuously secrete saliva, which hardens upon exposure to air, creating a sticky adhesive layer that secures the nest to the surface.
• Gradual Nest Formation: Over time, multiple layers of dried saliva accumulate, gradually forming a sturdy, oval-shaped nest firmly attached to its base.
• Final Usage: Once completed, swiftlets use the nest for egg-laying and rearing their young.

The composition of swiftlet saliva contains special compounds, including glycoproteins and sialic acid, which contribute to the high nutritional value and strong adhesive properties of the nest.

Factors Affecting the Quality of Bird’s Nest

The quality of bird’s nest is not solely determined by the nesting process but is also influenced by various factors:

• Diet of Swiftlets: A rich and diverse food source allows swiftlets to produce thicker, whiter nests with higher nutritional value. Conversely, food shortages can result in thin, darker nests with lower nutritional content.
• Living Environment: Humidity, light, and air quality play a crucial role. If the environment is too humid or too dry, it can negatively affect the color and texture of the nest.
• Swiftlet Species: Different swiftlet species produce nests of varying quality. The Edible-nest Swiftlet (Aerodramus fuciphagus) is known to produce the highest-quality nests, making it the most sought-after species in the bird’s nest industry.
• Harvesting Time: If the nest is harvested before egg-laying or before the young birds leave, its quality may be compromised, and it could disrupt the breeding cycle of the swiftlets.

Do Swiftlets Return to Their Old Nests?

Swiftlets often return to their old nests to renovate and continue breeding. However, if a nest is completely removed, they will build a new one.

To support the sustainable development of swiftlet colonies, nest harvesting should follow ethical guidelines, ensuring that:

• Nests are only collected after the young birds have fully matured and left.
• Some old nests are left intact to serve as long-term shelter for the flock.

Applications and Business Potential of Edible Bird’s Nest
