One of three Beluga whales spotted in Narragansett Bay has made its back to Nova Scotia. The Arctic whales were spotted back in May as far south as New Jersey.
Biologists are breathing a sigh of relief now that at least one of the beluga whales has returned safely to Canadian waters. They’re hoping this means the other two whales have also returned, if the trio continued to travel as a group.
Biologists worried about the health of the whales as they explored the Northeast and Mid-Atlantic waters. The animals are cold-water mammals, so one concern is heat stress. Another concern is a measles-like virus that’s recently hitting porpoises, dolphins, and whales. But the belugas appeared to be healthy based on assessments by federal fisheries managers.
At least one of the whales belongs to a declining population in the St. Lawrence estuary in Canada.
