""This shows that the decades-long effort to restore the river as a healthy habitat is working," crowed New York City's parks department."
"Dolphins are cavorting in the Bronx River of all places for the first time in at least five years, delighting New Yorkers.
They’re a hopeful sign that efforts to clean up the river, long plagued by pollution, are seeing some success, said city officials.
Local authorities also keep the river stocked with fish, which they believe may have lured in the dolphins.
“This is great news — it shows that the decades-long effort to restore the river as a healthy habitat is working,” the New York City Department of Parks and Recreation noted in a tweet with a video of the dolphins. “We believe these dolphins naturally found their way to the river in search of fish.”"
