Edible bird's nest is the nest made purely of swiftlet's
saliva secretion. This nest is usually found in caves
near shoreline cliffs or under eaves of house and is
hand-collected. Hairs and filth are then removed from
the nest before manufacturing.
The Swiftlet bird belongs to the Apodidae family, which is not the same as the common
Swallow bird. Swiftlet birds live in flocks along tropical seaside and consume wild insects.
From the appearance, Swiftlet differs from the so called "House Swallow" size wise.
The average body length of a Swiftlet is 9 centimeters, about half the size of a Swallow.
