BOSTON (WBZ-AM) -- The Massachusetts Department of Conservation and Recreation is calling it "a beautiful and rare sight to see."
While doing routine Boston Harbor Island rounds Tuesday, MassDCR spotted a juvenile humpback whale breaching the waters off Spectacle Island.
Now, the U.S. Coast Guard is sending a warning to boaters to watch for whales, as they have been spotted feeding and splashing around the harbor for the past few days.
DCR Boston Harbor Island District Manager Susan Kane said that, Wednesday morning, another whale was spotted by one of their boat operators in the same area as the whale shown in the video above.
"It's extremely unusual," Kane told WBZ NewsRadio 1030. "I think over the years, there's been a sighting here and there that kind of comes and goes, but in terms of having several whales--maybe there's between two and five that have been hanging around for several days ... I think the fact that there is a few and they've been here for a few days is very unusual."
She says that what we're seeing now is just whales doing what they do--jumping, breaching, and feeding.
"We think it's really an indication of all the good work MWRA and others have done to really make Boston Harbor clean again," she said.
