Study has proven that we will create conducive situations that simulate normal limestone caves.
. The nutritional information was expressed as being a percentage mainly because of the Examination of proportions in ecology, and the information were arcsine remodeled ahead of analytical exams. Furthermore, the nutritional cost of the breeding material was obtained by changing the nutrients into the level of nutrients per expense of breeding supplies in US dollar (US $).

In Indonesia and Malaysia, "farming" of nests is executed in objective-designed buildings or old empty residences with "tweeters" playing recordings of bird phone calls within the roof to catch the attention of swiftlets.
