#20: A Season of Unusual Sightings

As our season is winding down, we've been thinking about some of the unusual sightings we've had over the past couple months. We've mentioned some of them in earlier blog entries, like the unprecedented number of right whales off The Wolves (the island chain many miles north of the usual habitat) and the crazy cloud we saw in early September. But there have been other things that have caught our attention and made us wonder: What's going on this year?

One of the avian species we see every year are puffins, the cute football shaped black birds with the colorful striped beaks. Typically we only see four or five on any given day, but this year was a different story. Nearly every day we were out this season we had lots of puffins--puffins alone, in pairs or trios and occasionally in flocks of 8-12! And in late August we even had a rare sighting of an albino puffin! Why all the puffins? We have no idea, but we've certainly had fun watching them.


There were two other bird species that seemed much more prevalent this year than in the past: Northern Fulmars and Jaegers. Fulmars are usually found offshore, so the number of sightings we've had is surprising. What's great about fulmars is that they always seem a little curious about us. They literally turn their heads to check us out as they fly by.



Jaegers are aggressive seabirds that engage in kleptoparasitism--harassing other birds to force them to drop food they are carrying. As with puffins and fulmars, we've had a bumper crop this year. Find out more about all three of these interesting seabirds here.



The Bay was hopping with Bluefin tuna, especially in September. It's always exciting to see schools of these magnificent fish leaping out of the water as they pursue their unlucky prey.



In addition to the birds in the Bay of Fundy, we've also had an influx of humpback whales in areas that are usually the exclusive domain of right whales. It's not that humpbacks aren't seen in the Bay, they are, but they tend to aggregate further to the south and east. In years past, a big humpback count would be three in one day, but on a recent trip we counted 15! One of the humpbacks spent several minutes flippering, i.e. slapping it's long (12')pectoral fin against the water. Quite a bizarre sight when you're used to the black , paddle-shaped and comparatively stubby flippers of the right whale. The latin name for humpbacks is Megaptera novaeangliae, which means "big-winged New Englander"... it's easy to see why it got that name!



All of these species are not uncommon in the Bay of Fundy, but what has been interesting is the number of them. Why are so many humpbacks, fulmars, jaegers, puffins and tuna in the Bay this year? And could there be any correlation with the right whales' unusual northerly distribution, not seen in 30 years? Nature, as always, holds puzzles that we have yet to figure out.

#16: Calvin returns to the Bay

Great news! Calvin, #2223, one of the most famous right whales in the population, has returned to the Bay of Fundy. We sighted her on Sept 2 with her calf of the year by her side. This was her first sighting in northern waters since giving birth on the southeast U.S. calving ground early this year.

For those of you who don't know her story, Calvin was born in 1992 and it was during her first summer in the Bay of Fundy that her mother, Delilah, was killed by a shipstrike, leaving Calvin an orphan. We didn't think Calvin would survive without her mother, but amazingly she did. She was named (before her sex was known) after the character in the comic strip Calvin and Hobbes.

Like that little boy, Calvin the right whale showed resourcefulness and a surprisingly independent nature. Since then we've watched her grow up and have followed her exploits in the various habitats in which she's been sighted. In 2000, she became entangled in fishing gear but luckily was disentangled by the Provincetown Center for Coastal Studies in 2001. She still bears the scars on her head, body and peduncle from that experience. And in 2005 Calvin became a mother for the first time and brought her calf to the Bay of Fundy, just as her mother had done 13 years earlier.

Over the years Calvin's story has been used to illustrate the troubling issue of ship strikes--they are the leading cause of right whale mortality--and to help move the shipping lanes in the Bay of Fundy so they no longer cut through the main concentration of whales.

You can read more about Calvin and her namesake student scientists, The Calvineers, in the 2008 blog. Calvin is also one of our sponsorship whales, so if you'd like to follow her in the future you can sponsor her or visit the Catalog website.

#11: Ruffian's amazing recovery

During a recent trip out to sea, one of the whales we sighted for the first time this season was #3530, a whale we named "Ruffian" back in February of 2008. This sighting was a very exciting one for us because Ruffian had been horribly wounded by an entanglement in some kind of fishing gear prior to January 2008, and though he was no longer entangled, we did not expect him to survive due to the extensive injuries he had sustained. (See all of Ruffian's sightings by searching for #3530 on the North Atlantic Right Whale Catalog.)












He was sighted a few times after that, but the last shipboard photos were taken in April 2008 by the Provincetown Center for Coastal Studies (PCCS), and at that time he still looked terrible. But last Friday we got our first really good look at him in more than a year and we were thrilled with what we saw: his many wounds had healed, leaving only a few white scars on his back, head and tail. Although we don't know his age, Ruffian (named for his "roughed-up" appearance) is a young whale and that was probably the leading reason for his remarkable recovery. Young mammals in general have an enhanced ability to heal compared to older animals.



Entanglement in fishing gear is still one of the biggest threats facing right whales. Nearly 75% of the whales in this beleagured population carry entanglement scars, and we know that at least 20-30 right whales have died or been fatally wounded from entanglements. We are grateful that Ruffian is one of the lucky ones...

#36: Smithsonian's New Ocean Hall Exhibit

On September 25th, the Smithsonian's National Museum of Natural History in Washington D.C. hosted a gala for the opening of their new permanent exhibit, the Sant Ocean Hall. Suspended from the ceiling above the center of the Hall is the focal point of the exhibit--a full size model of a North Atlantic right whale. It's an actual replica of a cataloged individual, a female named Phoenix. You can see photos and a history of Phoenix on the North Atlantic Right Whale Catalog, search for catalog #1705.

Since 2004 Amy Knowlton and I have been working with the Smithsonian to make sure the model, and every other detail of information about right whales, is as accurate and up-to-date as possible. Because of that long relationship helping to develop that aspect of the exhibit Amy and I were invited to the black tie event, along with New England Aquarium Vice President of Research (and our fearless leader) Scott Kraus.

It was a great evening to see Phoenix and read all the information about right whales that we had spent years reviewing, and also to be the first (along with 1500 other guests) to see the exhibit. The Sant Ocean Hall is 23,000 square feet of fun facts and education about the world's most precious resource: the oceans that cover 71 percent of the earth's surface. The exhibit includes more than 650 marine specimens ranging from microscopic plankton to giant squid (and Phoenix, of course!) There are state of the art inter-active exhibits, video displays, and so much more than we could possibly see in the three hours we were there. We whale researchers, typically most comfortable in jeans, had to dress up and rub elbows with the elite of Washington. For some reason, we weren't featured in the New York social diary (scroll past first article) but as you can see we managed to look presentable!

Coming in our fall sponsorship newsletter we'll have an article about the creation of the model and our involvement in the project, as well as more about the opening itself. If you want to read more about it, here's the link to our sponsorship program.

#26: Lubec, our home away from home

Since the weather is keeping us on land, we thought we could take this opportunity to tell you a bit about the area we call home for 2 months a year.

Lubec, Maine, is the easternmost town in the United States and literally a stone's throw from Canada (Campobello Island, New Brunswick). It sits atop a hill overlooking Passamaquoddy Bay, and has stunning views in every direction. The natural beauty of the area--rocky coastlines, misty islands, and rolling hills covered with blueberries--never fail to wow first-time visitors. The woodlands are lush and mysterious, thick with moss and lichens. Bald eagles frequently soar overhead and seals frolic in the Lubec Narrows (the channel between Campobello Island and Lubec that turns into a rushing river of salt water at the peak of the incoming or outgoing tide).

Named for a town in Germany, Lubec is sleepy now (Pop: 1200), but it was once a bustling city --the sardine capitol of the world. Not only were there 48 sardine canning factories, but the town boasted herring smokehouses, movie theaters, hotels, four post offices, steamship service from Boston and a ferry to Eastport, Maine. The peak of Lubec's economic prosperity came during WWII when demand for herring and sardines was high and foreign imports were few. But in the years following the war, foreign competition increased, American tastes began to change (when was the last time you had smoked herring?), and fish stocks became depleted. With those three factors came a long economic decline.

One by one the various factories went out of business. The McGurdy Fish Company was the last operating commercial smokehouse in the U.S. when it finally closed its doors in 1992 (it is now a historical interpretive site open to the public). All the sardine canneries have shut down, with one exception--Peacock's-- but instead of sardine canning, they now raise urchins and sea cucumbers for foreign markets, and extract salt for "Quoddy Mist" sea salt. The steamship and ferry service stopped decades ago. The closest big city (and big airport) is Bangor, a two hour drive inland, and the nearest movie theaters are in Calais (pronounced Cal'is) or Milbridge, both an hour away.

But Lubec still has a lot to offer. There are restaurants and coffee shops, a good library, a few B&B's ... and two chocolate shops! There's also a popular music school called SummerKeys that brings musicians to the town and offers wonderful concerts during July and August.

To see more photos of the town, take a look at the 'Lubec' album in our online photo gallery of images from the season. And for more information about Lubec and the surrounding area check out: http://www.visitlubecmaine.com/

#14: Surface Active Group (SAG)

One of the terms we frequently use when describing right whale behavior is surface active group (SAG). A SAG has a fairly broad definition--two or more whales within a body length interacting at the surface--but typically, the SAG is comprised of one female and a number of males competing with each other in order to mate with her. Some SAGs are extremely active, with a lot of rolling and white water, whereas others are more sedate. The number of animals in a SAG can range from two or three to more than 40!

For years researchers presumed that the primary reason for a SAG was mating. However, conception is thought to take place in the winter (since gestation is about 12 months and right whales usually give birth between December and February), yet SAGs occur year round. Recent analyses of the composition and seasonality of these SAGs indicate that actually only about half of them include females able to reproduce. Thus, SAGs are not just for mating purposes.

Some have been documented to be all male, or all female, or all youngsters. Our colleague, Dr. Susan Parks from Woods Hole Oceanographic Institution, wrote a paper about SAG behavior in collaboration with Aquarium researchers (see below). She hypothesizes that, in addition to conception, SAGs may serve a variety of different roles including practice, play and social bonding.

Studying the behavior of marine mammals such as right whales is much more difficult than that of terrestrial species, because we get just a glimpse of these animals when they're at the water's surface. But the long-term photo-identification aspect of the Aquarium's program has enabled researchers to answer some very basic and important questions. To see video of a SAG see entry #11 Behavior Video (SAG).

#7: Our first day out, finally!

Yesterday was our first day on the water, and it was great! Because it takes us about 2 hours to get from Lubec to our survey area in the Bay of Fundy, we left the dock aboard our research vessel Nereid at 6:15 a.m. The crew consisted of Amy, Philip, Marilyn, Cyndi, Yan, Jonathan and two guests: Bill and Claudia. The weather was fine--winds were light and sky partly cloudy. By 9:15 we had found our first whales and the hours flew by as we worked one after another. By "worked" I mean we gathered all the information possible for each whale--the time of its sighting and its location (latitude and longitude), photographs of the head (for the callosity pattern) and the body and flukes (for any scars or marks), behaviors, and associations (whether it was alone or with other whales).

It was good to be back on the water, and we all fell into the various jobs without too much trouble. We took turns photographing, driving and recording the data.
One person is the designated "whalewatcher" and that person has to let the rest of us know which whale we're photographing, whether it's a new whale for the day or not, and what information we need from it. It's actually just about the toughest job on the boat--a lot of pressure and no breaks! Yesterday, Philip was whalewatcher, and, as always, he knew many of the whales on sight.

In the eight hours we were on the Bay, we photographed 36 individuals, including four mothers with calves! We also saw three calves without their mothers, but that's not unusual for this time of year in the Bay of Fundy. Calves are getting older and a bit more independent, so although they're still nursing, they may go off exploring on their own for hours at a time while mom is feeding. They reunite when one calls for the other.

The highlights of the day were the curious approaches from three different calves. Just like other baby mammals, right whale calves are curious about their surroundings, and it's not unusual to see a calf lifting seaweed onto its head or playing with a log. Sometimes it's the boat that interests calves and they have been known to spend many minutes swimming underneath and all around our boat, looking at it (and us?) from all angles.


After many hours on the water we finally began heading in at 5:00 returning to the dock at 7p.m., nearly 13 hours after we left! But our day wasn't finished yet. After a quick dinner (thanks, Monica!), we still had to process the data (all the information we entered into the computer for each sighting), upload images from the digital cameras (more than 700!), wipe down the equipment (salt air is tough on electronics), and prepare for the next trip out. Exhausted, none of us had any trouble getting to sleep.
