Due to the high economic value of EBN, swiftlets are being reared extensively in man- made houses in Indonesia, Malaysia and Thailand to increase the production of EBN. In recent years, the price of EBN increased drastically due to high consumer demand. This has led to EBN producers and the Malaysian government to’ make efforts for increasing the production of EBN through conservation and house farming. In several areas, the conservation of resources has been aided by the domestication of swiftlet species in bird houses.
