Edible-nest swiftlet

The edible-nest swiftlet, also known as the white-nest swiftlet, is a small bird native to Southeast Asia. This diminutive bird is renowned for constructing its nest from solidified saliva, which is a key ingredient in the highly prized bird's nest soup.

Let's delve into the bird's characteristics. The edible-nest swiftlet measures about 14 cm in length and weighs between 15 to 18 grams. It has blackish-brown feathers on its upper parts, while its underparts can vary in color. Its long, narrow wings, black bill, and feet make it quite distinctive. These birds are known for their unique calls, which they use for communication and echolocation.

There are six subspecies of the edible-nest swiftlet, each found in different regions. They primarily feed on flying insects and typically breed in colonies located in caves, on cliffs, or even in buildings. The nests they build are white and translucent, made entirely of their saliva. These nests are harvested to make bird's nest soup, a delicacy believed to offer various health benefits.

However, the extensive harvesting of these nests has put the edible-nest swiftlet population at risk in some areas. To address this, artificial birdhouses have been introduced to support nest farming. In countries like Indonesia and Malaysia, techniques such as playing recorded bird calls are used to attract swiftlets to these artificial structures. While effective, these birdhouses can sometimes be a nuisance in urban areas due to the noise and bird droppings they produce.
