Endangered whales gave birth to few babies this year as population declines

May 19, 2025 — A vanishing species of whale gave birth to few babies this birthing season, raising alarms among scientists and conservationists who fear the animal could go extinct.

The whale is the North Atlantic right whale, which numbers only about 370 and has declined in population in recent years. The whales give birth to calves off the southeastern United States from mid-November to mid-April, and federal authorities have said they need to have at least 50 calves per season to start recovering.

The whales didn’t come anywhere near that number this year. The calving season produced only 11 mother-calf pairs, scientists with the New England Aquarium in Boston said.

Fewer Right Whales Born This Year, Scientists Say

April 28, 2025 — At least 11 right whales were born this calving season, the New England Aquarium reported this week.

The number is lower than what scientists hoped, as the critically endangered species faces threats from human-caused activities. Entanglements in fishing gear and boat strikes are the leading causes of death and injury to the population.

Scientists say those injuries make it more difficult for right whales to reproduce and survive.

The 2024 calving season was more encouraging because roughly 20 individuals were born. However, the New England Aquarium noted that by last fall, a handful of newly born right whales had already disappeared.

Right whales stay in Cape Cod Bay longer, and later

June 16, 2022 — It isn’t high gas prices that changed the travel plans of right whales.

A new study in Global Change Biology by nine authors discovered that over the last couple of decades North Atlantic right whales are most active in Cape Cod Bay 18 days later than before.

That’s a shift — with a longer stay in the month of May — that could potentially bring the whales further into conflict with the region’s annual boating and lobster season and require an extended season of protections.

“The state has a flexible rule in place — where they can extend fishing closures and small boat speed restrictions — that now is in place up the coast to New Hampshire,” the study’s lead author, Dan Pendleton of the New England Aquarium, said. “Massachusetts Bay has seen more right whales than it used to.”

“One of the problems with migratory animals is they can get into big trouble moving into shipping lanes so if we can move and adapt the protections as (whales) adapt to climate change, that would be ideal,” Pendleton said. “So much seems out of our control but one thing we can do is push for regulations that are responsive to the needs of an endangered species.”

Beth Casoni, executive director of the Massachusetts Lobstermen’s Association, hadn’t yet seen the study, which was published June 7. Casoni said, therefore, she couldn’t comment until she has been able to read it.

Right whales’ survival rates plummet after severe injury from fishing gear

June 14, 2022 — Most North Atlantic right whales that are severely injured in fishing gear entanglements die within three years, a new study led by scientists at the New England Aquarium and Duke University finds.

North Atlantic right whales are a critically endangered specieswhose population has shrunk in recent decades. Scientists estimate fewer than 350 of the iconic whales are still alive in the wild today.

To examine the role fishing gear entanglements have played in the species’ decline, the researchers tracked the outcomes of 1,196 entanglements involving 573 right whales between 1980 and 2011 and categorized each run-in based on the severity of the injury incurred

The data revealed that male and female right whales with severe injuries were eight times more likely to die than males with minor injuries, and only 44% of males and 33% of females with severe injuries survived longer than 36 months.

New research shows climate change impacts on whale habitat use in the warming Gulf of Maine

June 10, 2022 — New research finds climate change is having an impact on how large whale species, including the critically endangered North Atlantic right whale, use habitats in the warming Gulf of Maine, showing that right whales’ use of Cape Cod Bay has shifted significantly over the last 20 years.

The study, led by the New England Aquarium and including researchers from the University of Massachusetts Amherst, the USGS Northeast Climate Adaptation Science Center, the Center for Coastal Studies, UCLA, the National Marine Fisheries Service, and the Canadian Whale Institute was published this month in the journal Global Change Biology. The authors set out to better understand the impacts of ocean climate change on phenology, or the timing of recurring biological events such as when plants flower each year. Using more than 20 years of data, the scientists measured shifts in whale habitat use in Cape Cod Bay, evaluating trends in peak use for North Atlantic right whales, humpback whales, and fin whales. The study found that peak use of Cape Cod Bay had shifted almost three weeks later for right whales and humpback whales. Changes in the timing of whale habitat use were related to when spring starts, which has been changing as a result of climate change. The study suggested that highly migratory marine mammals can and do adapt the timing of their habitat use in response to climate-driven changes in their environment, with results showing increased habitat use by right whales in Cape Cod Bay from February to May, with greatest increases in April and May.

“The time of year when we are most likely to see right and humpback whales in Cape Cod Bay has changed considerably, and right whales are using the habitat much more heavily than they did 20 years ago,” said lead author Dr. Dan Pendleton, Research Scientist in the New England Aquarium’s Anderson Cabot Center for Ocean Life.

New project aims to protect whales while developing offshore wind energy

June 3, 2022 — A new partnership between conservation and renewable energy is coming to Massachusetts.

The Right Wind project, through the combined efforts of the New England Aquarium, Cornell University, and LAUTEC US, aims to help offshore wind developers protect the North Atlantic right whale.

“We’re excited to be starting this project because it gives us an opportunity to develop tools that can help reduce the potential risks of wind energy development to North Atlantic right whales, a critically endangered species that numbers less than 350 individuals,” said Dr. Laura Ganley, an associate research scientist at the New England Aquarium.

Rare Right Whale Sightings Reported Along New England Shoreline

May 24, 2022 — Several people have reported rare sightings of North Atlantic Right Whales this month along the New England coastline from Provincetown to Portsmouth.

“It is pretty rare to see them that close to shore,” Heather Pettis of the New England Aquarium said.

With its bristle-like baleen plates and distinctive callosities decorating its head to its massive size and characteristic tail flukes, the North Atlantic Right Whale has been entertaining New Englanders this spring with some shoreline shows.

“Sure enough, there was a right whale skim feeding right off of Route 1A,” Pettis said. “This time of year whales sort of leave Cape Cod Bay, where they’ve been feeding over the winter. They disperse and we have these opportunistic sightings pop up.”

Study: Smaller Right Whales Have Fewer Calves

May 17, 2022 — A new study from the Woods Hole Oceanographic Institution and New England Aquarium has found that smaller North Atlantic right whales give birth to fewer calves.

The two organizations teamed up with multiple groups, such as the National Marine Fisheries Service and National Oceanic and Atmospheric Administration, to find this information.

Teams studied aerial photos of 41 female right whales taken between 2000 and 2019, finding that smaller mothers produced fewer babies.

Right whale defenders question energy industry donations

April 27, 2022 — A group opposing wind projects off the coast of Massachusetts released a report Tuesday that documents contributions from wind energy developers to environmental groups in the state, donations that the authors of the report say cast questions on the ability of groups to analyze the impacts that wind projects have on the endangered North Atlantic Right Whale.

The report, released by the Save Right Whales Coalition, catalogs $4.2 million between wind developers like Vineyard Wind, Bay State Wind, and Orsted to environmental groups in Massachusetts such as the Environmental League of Massachusetts, New England Aquarium, and the Woods Hole Oceanographic Institute.

The flow of money, coalition member Lisa Linowes said, raised a “red flag” for potential conflicts of interest when it comes to investigating the environmental impacts of offshore wind development in places where the North Atlantic Right Whale resides. The whale is one of the most endangered large whale species in the world, according to NOAA Fisheries.

“The public has come to trust the word of these organizations, that when they say wind turbines can be safely sited within and near the waters where the right whale lives, breeds, feeds, that they will be safe,” Linowes said. “Based on their public statements and based on the donations … we should question the priorities of these organizations.”

More Endangered Right Whales Are Leaving New England for Canada

April 25, 2022 — Local researchers are studying why North Atlantic right whales are migrating out of our area into more northern waters in Canada.

Some believe rapidly warming waters in the Gulf of Maine could be playing a role, but they’re just not sure how.

The North Atlantic right whale is one of the most critically endangered animals on the planet.

Researchers from the New England Aquarium are studying these majestic creatures and they think some of the answers might lie in their poop.

Dr. Elizabeth Burgess is a research scientist with the aquarium that studies hormone changes in right whales. Unfortunately, the easiest way to collect hormones is through their feces.

“So nutritional stress is of really great concern for this species, as is the reproductive viability as well. So all of these things we can, we’re using hormones to better understand what’s happening,” said Burgess.
