NEW YORK,-- New York transport officials said pumping avian distress and predator calls into a subway station has reduced the number of pigeons at the facility.
Kevin Ortiz, a spokesman for the Metropolitan Transportation Authority, said the agency contracted California firm Bird-B-Gone to install the $375 system at the Roosevelt Island subway station in December and officials have since seen "a noticeable decrease in birds and droppings," The New York Times reported Monday.
The system pumps pigeon distress calls and predator sounds through the facility every 2 to 10 minutes to discourage pigeons from making the station their home.
Some subway riders said they have not noticed a decrease in the pigeon presence.
"The bird scare noises annoy me more [than the pigeons]," rider John McCormick said.
I use one of these to keep the Red-Headed Woodpeckers from drilling into our house (Drivet-Acrylic Plaster).
Sounds like they put Woody in a vise and cranked it tight.
Unsettling.
Yeah, we’ve used ballons, streamers, predator statues, reflective tape, shotgun blasts etc, etc.
The little bastards are resilient and resourceful and just find another place to fire up their jack hammer.
The sonic repeller works the best by far, because it has a ~ 1 acre coverage and from a single mounting location, keeps them completely off all surfaces of our house, which is rather large.
The building I work in plays a recording of some kind of raptor to keep the Canada geese away. It is just awful.
Fortunately you can’t hear it at all inside the building so it’s not all that bad.
