Dolphins herded out of shallow waters near Eastham

Small boats herded 39 common dolphins out of shallow water near Thumpertown Beach in Eastham Saturday evening, according to an International Fund for Animal Welfare spokeswoman.

The group received a report of dolphins stranded in ankle-deep water at about 7:30 p.m., but when volunteers arrived half an hour later the dolphins had refloated and made their way to deeper waters on their own, said Kerry Branon, the spokeswoman.

None of the dolphins were injured, Branon said.

Volunteers herded the dolphins further out to sea using small boats with acoustic deterrents, she said, and returned at low tide this morning to make sure the they had not returned to shallow waters.

“That’s a very good sign that the animals moved out to deeper water,’’ she said. “We are going to go back and check again at high tide.’’

Branon said International Fund for Animal Welfare volunteers also helped two groups of dolphins out of nearby Wellfleet Harbor Saturday: about 40 common dolphins and between 60 and 100 others that appeared to be Atlantic white-sided dolphins, though volunteers did not come close enough to verify the species.

As of Saturday, about 250 dolphins had been stranded near Cape Cod since January, Branon said.

“It’s a busy year for dolphin sightings on Cape Cod,’’ she said.
