This is a common practice in Malaysia. The Chinese community put these speakers in empty buildings to attract the Edible-nest Swiftlet (Aerodramus fuciphagus) which as its name suggests is where the nest in Birds Nest Soup comes from ….
its not as harsh as most Chinese cuisine as the birds themselves aren’t eaten and nests are only harvested after the birds have finished with them – they do also get a safe warm place to build them and raise their families (in a country otherwise overrun with wild cats and other predators) but its a noisy process which annoys the other ethnic groups….
(this is where it all happened)
Segamat – Wikipedia, the free encyclopedia
> China Press reported that enforcement officers from the Segamat district council had dismantled 100 sets of loudspeakers which were used to attract swiftlets in a 20-storey building, following a court order.
Residents living near the building in the town area had often complained about the noise from the building.
Apparently, three swiftlet farming operators had been using the building to breed swiftlets which are prized for their nests.
The paper quoted council secretary Mustaffa Kamal Shamsuddin as saying the council faced difficulty in acting against swiflet farming because although the state government had banned it, the federal government continued to issue permits.
