The Post's report details only the past two years of Port Authority's fusillade, but the extermination program has reportedly been in effect since the 1990s. According to wildlife authorities in both New York and New Jersey, however, the practice of shooting endangered or threatened species is illegal. But, as an agency spokesperson told the Post, Port Authority has been granted a permit to shoot osprey to ensure flight safety at area airports because the birds "did not respond to non-lethal harassment."
Animal welfare activists are alarmed at Port Authority's actions. But some, like David Karopkin of the urban advocacy group GooseWatch NYC, are not surprised. "There's no incentive to take a long-term look at this issue," Karopkin said. "Killing is a way for [Port Authority] to pat themselves on the shoulder and say they're protecting people."
