What is that clicking noise I hear as I enter the World Showcase at EPCOT?
You may have noticed a subtle clicking noise as you walked into the World Showcase at EPCOT, before. Many people often wonder where it's coming from and what it may be doing -- other than disturbing the Magical music playing in the background at EPCOT. 
Well, simply put, the noise comes from bird deterrants. The little speakers play noises that are supposed to mimic distress and predator calls and keep birds from landing and roosting in outdoor locations.
At the World Showcase, they are installed on both of the retail locations, just as you enter the area. So, it may sound like the clicking noise is welcoming you to the World Showcase, when, in fact, it is chasing off unwanted visitors to the area.
