Edible Cave Nest Swiftlet

There are two type of swiftlet species that build edible nest in the cave namely Aerodramus maximus and Aerodramus fuciphagus. Maximus make their nest with more siliva togather with feathers therefore their nest appear black. 

The black nest is heavier and thicker than white nest.

Most nests are built during the breeding season by the male swiftlet over a period of 35 days. They take the shape of a shallow cup stuck to the cave wall. The nests are composed of interwoven strands of salivary cement. The nests have high levels of calcium, iron, potassium, and magnesium.
