"BAYA" light manifests from the elegant nesting colonies made by the Baya Weaver bird. Its a sparrow sized bird known for its long hanging woven nests.
It is the males which build their nests, stripping long grass and paddy, and weaving them into place between numerous trips. The strips are green when new and recent structures can be recognized by the greenery. Once the nests are built, the females arrive and chooses a male whose nest she likes, and occupies the nest, while the male only then completes the entrance to the nest.
