The Indian Swiftlet or Indian Edible-Nest Swiftlet (Aerodramus unicolor) is a small swift. It is a common resident colonial breeder in the hills of Sri Lanka and southwest India. The half-cup nest is built on a vertical surface, often in a cave. The male swift uses thick saliva to construct the white, shiny nest into which two eggs are laid. The relatively tasteless nests are harvested, and mixed with chicken, spices, and other flavours as bird's nest soup, a supposed aphrodisiac. This 12 cm long species is mainly dark brown above and paler brown below. Wikipedia →
