The MTA has installed the recorded sound of birds at the Roosevelt Island station.
The $375 bird call system releases distress and predator calls every two to 10 minutes.
The pigeons had been leaving feathers and feces around the station.

The bird call system appears to be working. But one rider said he found it more annoying than the pigeons.
