Moreover, the nutritional expense of the breeding materials was obtained by changing the nutrients into the quantity of nutrients for every cost of breeding resources in US dollar (US $).
Most nests are built during the breeding period via the male swiftlet more than a period of 35 times. They just take the shape of a shallow cup stuck for the cave wall.
