9 am and 2 pm Whale Watch - Krill
Like September for weather - cool and perfectly clear air from the NNW making for unlimited visibility. Seas about 1 to 1.5 foot (from the NNW) and just a hint of a swell from the E when on Stellwagen Bank.
For the AM trip we started at the southwest corner of Stellwagen Bank, watching Nile and her pup, and then we had a chance to also watch two separate young humpbacks (one ID'ed as Forceps) afterwards (Forceps was not too far from Nile and calf, while we had to move a few miles E to see the other whale).
Nile seemed fairly quiet (for her activity level) on this morning's encounter, while the "spunky" calf made quite a few lobtails and tail breaches before the two settled into a nursing period (more about this follows). Forceps and the other young humpback seemed to be deep feeding, spending several minutes at a time below the surface before surfacing for a few breaths in seemingly random locations.
We often get a chance to observe what we interpret as nursing behavior when we find mother/calf pairs in quiet areas away from actively feeding whales, especially in the spring and summer (by the fall the calves are nursing less and less and feeding with the adults more and more). However, the nursing itself is not normally observed above the surface, but is observed (we believe) indirectly, as follows:
A mother humpback has her two mammary glands on her abdomen. A calf can be detected as nursing when we see the calf dive down on one side of the mother's abdomen or tail, surface a moment later on the other side of her abdomen or tail, and then repeatedly go back and forth from one side to the other several times. It is an interesting and very significant (even if subtle) behavior for whale watch passengers to be able to watch.
For the PM trip we again headed to the southwest corner of Stellwagen Bank, where there were seven to eight humpbacks scattered over the area. We spent most of our time with Follicle and her calf and later with Tongs, the whales who seemed to be the most active of all the whales in the vicinity. Tongs provided an unusually dramatic display of lobtailing. We saw her breach at a fair distance, which caught our attention immediately, but she had changed over to tail breaching, lobtailing, and flipper slapping before we eased over to her.
However, what was most impressive at close range were her lobtails - not only is Tongs one of the largest humpbacks in "our" population, but she lobtailed (both rightside up and in an inverted fashion) with much higher than the typical force, so that she made about the loudest lobtail slaps I've heard in a very long time - in fact, the slap could literally be felt, transmitted from the water throughout the surfaces of the boat. Interestingly, the inverted lobtails were somewhat louder and had a "sharper" sound than the "normal" lobtails. Quite a display...
Almost no birds were seen offshore on these trips - little or no surface bait was available for them where we were watching whales, it would seem.
11 am Whale Watch Trip - KrillWe had a beautiful day offshore aboard the Son II with Capt. Joe. Lght winds from the northwest produced seas of less than 2 feet. We headed to the southwest corner of Stellwagen Bank, but were not able to find any of the whales that we had been watching over the past few weeks. This is a stark reminder that these whales are constantly on the move as they try to find the most productive areas offshore.
As we continued east, we crossed over Stellwagen Bank. Soon we picked up our first sighting which was a pair of humpback whales. This pair turned out to be Follicle and her calf of this year. The calf was breaching next to mom as they continued to slowly swim to the west. As we watched Follicle and calf, we noticed the calf surfacing on alternate sides of the mom, a sure sign that the calf was nursing. So we left this pair and continued east.
Soon we observed more blows (spouts) a few miles to the northeast. In this area, we found a group of approximately 20 to 25 humpback whales and a few minkes whales that were scattered over a 5 mile area. As we moved from group to group, we noticed a small cluster of humpback whales that had started to feed at the surface. Soon we were surrounded by feeding whales all around the boat (see above image).

One humpback whale was a animal named Terrace (see above image). Terrace is easy to recognize for she is missing the left half of her tail (fluke). This cut is extensive indicating that it was probably caused by a collision with a large commercial vessel. But Terrace is doing well and her injury doesn't appear to negatively impact her behaviors.

As we drifted with the whales, one animal broke away from the group to come over to the boat (see image above). This whale turned out to be Colt, a very friendly male humpback whale. It was amazing to see Colt directly under the boat as he drifted with us for over 10 minutes. With this whale right next to the boat, we got a good feel for how big, powerful and beautify these animals truly are. as we headeWe had to go east of the bank which meant an extended trip, but the extra distance and trip time was well worth it.
We are seeing fewer seabirds offshore, but did have quite a few Cory's shearwaters, greater shearwaters, sooty shearwaters, laughing gulls, Wilson's storm petrels and one juvenile Northern gannet.
