The Metropolitan Transit Authority, the agency in New York City that is in charge of the subway system, among other things, has installed a soundtrack of “distress and predator calls” in the Roosevelt Island subway stop, hoping that the audio will drive pigeons and their feathers and droppings away from the station. It won’t work. Especially when people are still “delivering bread and bagels for the pigeons because [they fear] that they are having trouble finding food during winter.”
The MTA’s solution is at least better than the gel being used in Utah that is causing problems for an array of species in addition to the intended target, pigeons. At least the MTA is doing no harm to other species.
