Rare sighting: Dolphins caught on video in the East River in Greenpoint

The warm weather Tuesday helped one Brooklyn resident capture a rare sighting of dolphins swimming in the East River.
Dr. Howard Rosenbaum, the director of the Wildlife Conservation Society Ocean Giants Program and a senior scientist from the New York Aquarium, believes they appear to be common dolphins based on the video. Rosenbaum says the sighting is not common.
The video was captured by Cailin Doran, who says she was in Transmitter Park in Greenpoint enjoying the views when she spotted the dolphins.
"They just seemed so playful and fun and there was three of them, two bigger ones and a smaller one, and in that moment it felt so hopeful after such a sad year in kind of the best way," says Doran. "Things are moving forward."
Rosenbaum says it doesn't look like the dolphins were injured or in distress. He says there is a risk to their safety if they continue down the East River into the harbor area.
