Nest of Babui

classification

Bird’s nests are divided into the two following major categories:
House Nest:
Swallow builds nest inside a house called swiftler house. House roof is made of wood. The internal setting of the house imitates the temperatures, luminosity and humidity of natural caves. Average temperature is 28 to 30oc and humidity lies between 89 to 90%, environment is humid and dark. Swallows leave the swiftler house in the morning to look for food outside until evening. Since environment is ideal, there is little impurities and feathers in the bird’s nest and it is cleaner with more complete shape like a boat or a spoon. It also expands more than cave nests. White nests are softer and smoother while golden nests and red (blood) nests are crispier in texture. This is due to higher mineral content in golden nests and blood nests.
