Feds take most humpback whales off endangered species list

September 7, 2016 — HONOLULU — Federal authorities took most humpback whales off the endangered species list Tuesday, saying their numbers have recovered through international efforts to protect the giant mammals.

Known for their acrobatic leaps from the sea and complex singing patterns, humpback whales were nearly hunted to extinction for their oil and meat by industrial-sized whaling ships well through the middle of the 20th century. But the species has been bouncing back since an international ban on commercial whaling took effect in 1966.

The moratorium on whaling remains in effect, despite the new classifications.

The National Marine Fisheries Service said it first had evidence to indicate there were 14 distinct populations of humpback whales around the world. It then said nine of these populations have recovered to the point where they no longer need Endangered Species Act Protections. These include whales that winter in Hawaii, the West Indies and Australia.

Before, the agency classified all humpback whales as one population. They had been listed as endangered since 1970.

“Today’s news is a true ecological success story,” Eileen Sobeck, assistant administrator for fisheries at the National Oceanic and Atmospheric Administration, said in a statement.

Study finds ship noise disrupting humpback whale feeding

August 12, 2016 — One of the biggest threats to humpback whales spending their summers in New England is being hit by a passing ship.

But a collision isn’t all they have to fear. A study published Wednesday found that low-frequency noise from passing freighters and cargo ships near the coast could be disrupting their ability to feed.

A team of researchers examining the foraging behavior of 10 whales in the Gulf of Maine found that some of these 40-ton cetaceans descended more slowly in the presence of ships, giving them less time to find the food they’d normally consume. The whales also conducted fewer side-roll maneuvers — a technique they use to feed on a type of fish known as a sand lance that’s found just above the sea floor.

“Overall, I was kind of surprised that we were able to detect any response statistically just because these humpback whales are very adaptable,” said Hannah Blair, a graduate student at Stony Brook University in New York who led the analysis on the data.

Whales, dolphins and other marine life depend heavily on sound to communicate with one another and to search for food. A growing body of evidence in recent decades suggests noise caused by humans, including ship noise, is wreaking havoc on marine life. It masks sounds produced by prey and alters the behavior of prey.

Findings like these prompted the National Oceanic and Atmospheric Administration in July to announce a project to address noise that impacts aquatic species and their habitat over the next 10 years. The goals include educating the public about the problem and “minimizing the acute, chronic and cumulative effects of noise on marine species and their habitat.”

The study offers the first evidence that noise could be harming the feeding behavior of humpback whales.

NEW YORK: Lookout for humpback whales in the Long Island Sound

August 1, 2016 — The National Oceanic and Atmospheric Administration is asking boaters to be on the lookout for humpback whales in the Long Island Sound, according to a press release.

There have been recent sightings of humpback whales feeding on small fish, possibly menhaden, in the western portion of Long Island Sound, NOAA officials said.

Humpback whales are about 60 feet and weigh nearly 40 tons.

The federal agency is asking boaters to follow safety viewing guidelines, which includes staying 100 feet away from whales.

“Humpbacks create bubble clouds to corral their prey and then lunge through the center to swallow the small fish,” according to the NOAA press release. “Fishermen or boaters in these bubble patches run the risk of colliding with a massive whale as it rapidly approaches the surface.”

Scientists, fishermen plot ways to prevent whale entanglements

May 25, 2016 — PORTSMOUTH, N.H. — Nette Leverman was reading from a sheaf of papers she held in her hand, detailing the interactions between whales and fishermen in Greenland, where she is a population biologist.

Humpback, minke, fin and bowhead whales were getting caught in fishing line and nets in the waters off the country’s coast. It’s a familiar refrain, heard over and over Monday, the first day of a four-day international workshop on large whale entanglements.

“We’ve known for decades about this problem, yet solutions to it remain elusive,” said Tim Werner, a senior scientist at the New England Aquarium, and one of the workshop’s organizers.

Governments and fishermen around the world are feeling the strain from an increasing numbers of whales being snared in fishing gear as some whale species rebound and as the amount of gear in the water increases for fishing, aquaculture and other uses.

The Oozing Whale Skeleton of New Bedford

April 8, 2016 — In New Bedford, Massachusetts, the setting of Herman Melville’s story of the Great White Whale, there is a suspended whale skeleton that has been oozing oil for over 15 years.

The New Bedford Whaling Museum is filled with cannibal forks, the world’s largest scrimshaw collection, canned whale meat, and 2,500 handwritten accounts of whaling voyages. Here the unusual is usual, including its collection of four whale skeletons hanging over the entrance. These giant marine mobiles include a humpback named Quasimodo, a fetal right whale and its mother Reyna, and the biggest — a blue whale called KOBO.

Wildlife secrets revealed with advanced tracking devices

February 29, 2016 — BOISE, Idaho (AP) — Solar-powered trackers on wings have recorded California condors soaring to 15,000 feet, while locators attached to humpback whales have revealed 1,000-foot dives to underwater mountains. And GPS collars on Yellowstone grizzly bears are giving new insights into one of the most studied large carnivore populations in the world.

Technological advances in recent years have allowed what could be the most inquisitive Earth dweller of them all, humans, to invent ever more ingenious tracking devices to find out what their fellow inhabitants are up to.

“It’s a large field that’s developing very fast,” said Alex Zerbini, a research biologist with the National Oceanic and Atmospheric Administration‘s National Marine Mammal Laboratory in Seattle. “There are many types of tags being developed for many species of marine animals.”

Scientists say the trove of information thanks to ever smaller, tougher and more powerful tracking devices is leading to discoveries that could be used to make better wildlife and habitat management decisions.

The devices are also revealing the secret lives of hard-to-study animals.

For example, Zerbini said, scientists recently discovered humpback whales diving to underwater mountains on a regular basis, and also making the dives during migrations.

In Yellowstone National Park and the surrounding area, more sophisticated tracking devices on grizzly bears are providing information, notably on their ability to find food, that could be a factor in whether Endangered Species Act protections are lifted.

NJ/NY Boaters: Watch for Whales Close to Shore

July 17, 2015 — The following was released by NOAA Fisheries:

Stay safe, stay alert, and keep your distance

On Monday, an adult female humpback whale and her calf were seen close to the shore, off Sandy Hook, NJ, reportedly feeding on menhaden. 

 Asbury Park Press posted a story, with photographs of the whales against a backdrop of people on the nearby beach.

It is not unusual for humpback whales to come close to shore when they are following their food.

NOAA Fisheries asks boaters off New Jersey and in New York Harbor to keep a close eye out for these feeding whales, and to remember to follow safe viewing guidelines, which include staying 100 feet away from the whales for your safety and theirs. Humpback whales can reach lengths of 60 feet, and can weigh around 40 tons. 

In addition to the potential risk of a collision, the close proximity of a boat may cause a whale to stop feeding. All whales in U.S. waters are protected by the Marine Mammal Protection Act, which makes it illegal for people to harm, injure, kill, chase, or harass whales or any other marine mammal. Harassment includes any activity that results in changes to the whales’ natural behaviors, such as feeding. Penalties for Marine Mammal Protection Act violations are fines of up to $20,000 and up to one year in prison. In addition, some whales, including humpback whales, are also protected under the Endangered Species Act.
