စရိုတ်

The edible-nest swiftlet feeds over a range of habitats from coastal areas to the mountains, occurring up to 2,800 metres above sea-level on Sumatra and Borneo. Its diet consists of flying insects which are caught on the wing. It often feeds in large flocks with other species of swiftlet and swallow.

It breeds in colonies in caves, in a cleft in a cliff or sometimes on a building. The bracket-shaped nest is white and translucent and is made of layers of hardened saliva attached to the rock. It measures about 6 cm across with a depth of 1.5 cm and a weight of about 14 grams. Two white, oval, non-glossy eggs are laid.

The nest used in bird's nest soup is composed almost entirely of saliva with little or no plant material. The soup is made by soaking and steaming the nests in water and is said to be an aphrodisiac and to have various medicinal qualities. The nests can fetch high prices and many colonies are harvested commercially.

Some populations such as those in the Andaman and Nicobar Islands have been harvested extensively leading to them being considered critically threatened under the IUCN criteria.

The use of artificial bird houses is growing. A detailed account of modern nest farming and marketing techniques is given by David Jordan (2004). In Malaysia, "farming" of nests is performed in purpose-built structures or old empty houses with "tweeters" playing recordings of bird calls on the roof to attract swiftlets. In urban areas, such "bird houses" may be considered a nuisance by neighbours due to the loud bird calls and bird feces.
