In the jungle city of Pangkalan Bun in Borneo (Indonesia), large multi-story concrete tower buildings (easily the tallest structures) known as "bird houses" rise throughout the town. They provide nesting space for edible-nest swiftlets which are there to provide nests (made of saliva) for the making of Chinese bird's nest soup. This is a very big local business with 1 kg of material worth ~500 USD. The natural sounds of the birds are supplemented with numerous speakers placed in the buildings to attract additional nesters. Pangkalan Bun rings with this continuous sound 24/7.
