Authentic bird's-nest soup is made from nests of some species of swiftlet, mainly the edible-nest (or white-nest) swiftlet (Aerodramus fuciphagus) and the black-nest swiftlet. Instead of twigs, feathers and straw, these swiftlets make their nest only from strands of their gummy saliva, which hardens when exposed to air.
This flight arrangement might benefit the bird's control and maneuverability in the air. [12] The swiftlets or cave swiftlets have developed a form of echolocation for navigating through dark cave systems where they roost. [13] One species, the Three-toed swiftlet, has recently been found to use this navigation at night outside its cave roost too.
The edible-nest swiftlet (Aerodramus fuciphagus), also known as the white-nest swiftlet, is a small bird of the swift family which is found in Southeast Asia. Its opaque and whitish bird nest is made exclusively of solidified saliva and is the main ingredient of bird's nest soup , a delicacy of Chinese cuisine.

The Himalayan swiftlet has a twittering chit-chit roosting call, and also has a piercing teeree-teeree-teeree call.. What distinguishes many, but not all, swiftlet species from other swifts and indeed almost all other birds (the oilbird being an exception) is their ability to use a simple but effective form of echolocation to navigate through the darkness of the caves where they roost at night ...
