Chinese and gain popularity every year for its health benefits (especially for
the skin). This kind of nest had been used in China since 400 years ago an
prepared as bird’s nest soup.
Swiftlets nests are classified into two major
classes derived from the place where the nest had been obtained (in the
building) and also the nest from the caves. Nests derived from building are more
easily processed and have a first-class grade. While nests collected from caves
contain foreign materials such as feathers and other mainly grass. So, this
bird's nest should undergo a cleaning process before being marketed.

buildings built in the center of small town that can be somehow disturbing for
public.
What makes the price nest swiftlets expensive are
the needs to be put everything in right conditions because the building used as
home nest should meet the needs of swifts such as; lighting, humidity and
