From the Queens Tribune:
...teams will sweep City parks within a five mile radius of the airports, rounding up all the Canada geese during their flightless molting season until the end of July. The birds will then be taken to an offsite area where they will be euthanized in carbon dioxide chambers.
According to Bannerman, 2,000 geese isn’t the cut-off mark. The City hopes to remove all geese within the five mile radius.
I clarified with the reporter what exactly Bannerman was referring to:
"Do you mean more gassing? Or by other methods."
And his response was:
"All gas, all the time. I specifically asked if any would be relocated or anything other than gassed. Got a definite no."
