Today's trip was absolutely out of this world. We had some amazing looks at the humpbacks that are in our waters. We did travel around the back side of the Cape today, heading passed the area where the Pilgrim Monument sits.


Learn about the whale, dolphin and porpoise sightings in Cape Cod Bay and Massachusetts Bay. Join naturalists - Krill, Fred, Joanne, Dianne, Leah, Lauren, Tammy, and Michael - aboard Captain John Boats as they head offshore each day from April through October to view the unique coastal marine wildlife off New England. Our intern Ian will also be providing seabird reports.








Today we headed toward Peaked Hill Bar, an area just off Truro, MA, where there have been very good whale sightings lately. As we got into that area, we saw several large splashes in the distance. These large splashes were being produced by a breaching humpback whale!

To witness a breach is a very special event, as we only see this behavior on about 10% of our trips. As we approached this animal, the whale actually breached two more times before rolling onto its side and raising its long white pectoral flipper in the air, giving us a great look at the long “wings” of the humpback whale. Humpback whales have the longest pectoral flippers of any marine mammal and can reach 1/3 of the whale’s body length.

After several minutes we left this whale and continued to move toward the East where we picked up a group of seven humpback whales who were feeding together. This group was producing bubble nets to concentrate their prey and then lunge feeding at the surface to engulf as much food and water as possible. As the whales would come up with mouths wide open, we got excellent looks at the baleen which hangs down from the upper jaw.

Also in this area were 5-8 minke whales, a pair of finback whales and a huge group of sooty shearwaters and gulls, who were feeding right alongside the humpbacks. On our way home we got quick glimpses of several other lone humpback whales, some who were feeding at the surface. Another beautiful and amazing day of whale watching!






















Spike started kick feeding in addition to bubble netting with the group. The huge splash created by Spike's tail as testament to the immense disturbance that this activity caused on the water's surface.

11 AM Whale Watch aboard the Son IV - Joanne
We left Plymouth Harbor on the 11 AM whale watch aboard the Son IV with calm seas, mostly clear skies and light winds. Terns were active feeding off of Plymouth Beach and throughout the Harbor.
We traveled to the southeastern edge of the Gerry E. Studds-Stellwagen Bank National Marine Sanctuary where we got to spend time in the company of nearly a dozen feeding humpback whales. Sooty sheartwaters, herring gulls and laughing gulls were actively engaged in the feeding behavior of the whales, being used as cues to where the whales’ bubbles would surface.

We started with a group of six humpbacks coming up through a bubble net together, a spiral of bubbles which helps to trap prey. Right off the bow of our boat, we could see light green foaming water.

Abrasion, Coral, Entropy, Joy, Stub & Touché came up in perfect coordination with mouths wide open, all 6 whales dragging as they filtered the hundreds of gallons of salt water from their mouths, trapping the small schooling fish. When the whales surfaced, we could see the baleen hanging from the upper jaw, the pink roof of the mouth (palate) and the tubercles or stove bolts (bumps) covering their heads, each with a hair like whisker that may help detect sensory information about their environments.
Echo was also kick feeding nearby. Her preferred style of feeding is almost always a combination of kicking and bubbling. She’s got a very dramatic high kick, usually kicking 2-3 times before circling to blow her bubbles and trap prey. She was first seen in 1988 and was named for a series of parallel lines on her left fluke that look like the pattern of sounds produced during echolocation. Genetic studies indicate that she is descended from the same distant ancestors as other well known Stellwagen humpbacks Cardhu and Trident.
Humpback whales are very social animals, especially when feeding, and sometimes form associated groups which may last a few minutes or hours. In this feeding frenzy, the group would vary from 6 to 4 to pairs back to 6 as they searched and devoured prey.

Coral seemed to be the most varied, joining and leaving the group on numerous occasions, very loose associations when feeding. Coral is the son of a whale named Silver, who only had half of her tail and died in 1991 from an entanglement in fishing gear. Coral’s name was suggested by children in the Eastern Caribbean, highlighting the importance of our areas as different types of habitats for the same population of whales, feeding/nursing on Stellwagen and breeding/calving in the Caribbean.
The rake marks on his tail indicated he survived a killer whale attack early in his lifetime. Coral is very easy to identify in the field due to a white patch of scarring behind his blowholes. Coral’s family has taught us quite a bit about humpback whales; his sister was one of the first whales tracked from birth to her own first birth, providing researchers with important information on ages of sexual maturity and reproductive rates and intervals.
Joy was named for three marks on the right fluke that look like letters spelling out the word Joy.
Abrasion was born in 1997 and is the fifth known calf of Liner. While most whale are named for a pattern on the bottom of their flukes/tail, Abrasion was actually named for a very prominent white scar along the left side of her caudal peduncle (where her tail and body meet). We don’t know the cause of this injury, but it makes her very easy to identify. Abrasion spends more time in the Stellwagen Bank area than any of her other known relatives.

Stub is one of the older whales to have been cataloged, first seen in 1979. Stub is more often in the northern Gulf of Maine/Bay of Fundy. He’s named for his stub like dorsal fin, which is easily distinguished. He also has a very unique fluke with ‘rake’ marks from killer whales teeth scraping along it, most likely as a calf.

Entropy had the most notable fresh scars on her body, which over the years have indicated she’s had several different entanglements, one quite recently. She was first seen in 1997. She was disentangled by a team of rescuers on May 15, 1998. In 2005, she was seen with her first calf and only known calf. She has scarring around her tailstock, as well as raw pink scars on the leading edge of her flukes and caudal peduncle. Overall, her skin was a little grayer too. Over 60% of the humpbacks in the Gulf of Maine have entanglement scars on their bodies and each year, 10-20% get entangled. Some whales get out of fishing gear on their own, some, like Entropy in 1998 are disentangled, and some we never see again. .
As we watched the groups and pairs and single whales feed, a whale started breaching not far from us. Tail breaches, full spinning breaches and a very familiar dorsal fin appeared belonging to—COLT! Colt is one of few whales which is named for his mother, Equus, the genus of horse. He was born in 1981 and is 30 years old this year. Following whales for their lifetime allows to He is quite well known for his curious behavior around boats, often making them late returning to port.
It was another incredible day whale watching with Captain John Boats off Stellwagen Bank!
