A common dolphin and an Atlantic whitesided dolphin were released at Herring Cove Beach in Provincetown Tuesday afternoon after two separate strandings in Wellfleet in the morning, said Misty Niemeyer, necropsy coordinator for the International Fund for Animal Welfare Marine Mammal Rescue and Research team.

Four common dolphins were reported stranded off Commercial Street at around 8, and two Atlantic whitesided dolphins were reported stranded on Lieutenant Island at around 9:30.

Three of the common dolphins died before the IFAW team arrived on site, Niemeyer said, and the fourth was released in Provincetown. The smaller of the two Atlantic white-sided dolphins had to be euthanized, and the second was released with a satellite tag in Provincetown.

On Monday, the IFAW team responded to a report of two common dolphins stranded in Wellfleet. One had to euthanized and the other was released off Herring Cove.

This year is shaping up to be a busy one, with the team responding to 202 strandings so far, Niemeyer said.

The average annual response is 250. Niemeyer said anyone who sees a stranded animal should immediately call the marine mammal team at 508-743-9548 and not try to put the animal back in the water.
