Sighting from Tamalpais Charters vessel The Tamalpais for the Marine Mammal Center

9am:

On this special trip for the Marine Mammal Center, we headed west towards the Golden Gate Bridge. We spotted a few harbor porpoises near Cavallo Spire and some harbor seals close to the south tower of the Golden Gate Bridge.

As we headed out through the strait, we noticed lots of bird activity. There were a variety of types of birds present, including elegant terns, parasitic jaegers, brown pelicans, common murres, and Brandt’s cormorants.

Right around the demarcation line we spotted the first spout. It was a humpback whale. One of the first behaviors we saw was a body roll, where we got a good look at the pectoral fin of the humpback.

The whale was surfacing every few minutes and arching its back to dive, but we weren’t seeing any flukes from the animal at first.

The whale was definitely feeding. Birds hovered all around the spots where it surfaced, attempting to get the leftover anchovies.

The animal slowly moved west past the demarcation line. As we followed, we spotted a second spout.

We saw a shallow fluke dive from this animal which will hopefully help us identify the individual.

The wind was increasing and the tide was beginning to ebb, so we eventually started heading back in to the bay. On our way back to Tiburon, we stopped by Pier 39 to look at the sea lions.

There were also lots of birds in the area.

We also took a look at some of the whale bones on Angel Island, where the Marine Mammal Center performs their necropsies.

11am:

On our first trip of the day we found one humpback whale near Mile Rock, near the end of the Golden Gate Strait. The whale was in 64 feet of water.

There was a lot of bird activity and bait in the area, but we did not observe any feeding behaviors or fluke dives.

The whale moved in large circles and slowly moved east with the incoming tide.

2pm:

On our next trip we found the same whale near Mile Rock again. It was close to the shoreline at Land’s End.

We saw one fluke dive from this animal, which we tentatively identified as Black October.

We saw a lot of feeding activity from this animal, including lunge feeding and roll feeding. There were birds hovering over the whale as well.

There were lots of boats in the area, including two large ships. One of the ships was careful to maneuver around the whale. An ebbing tide and northwestern wind created rough conditions in the Golden Gate Strait, making it harder to approach the whale.

We spent about 40 minutes with this animal.

9am:

On our first trip of the day we traveled down to Pacifica and found two humpback whales lunge feeding in 28 feet of water.

One of the whales surfaced for a brief moment before disappearing. The dorsal fin may have been that of Gator, a familiar visitor to our waters.

The other whale stuck around and fed in the area. We saw lunge feeding, anchovies boiling at the surface, and lots of bird activity.

At one point the whale approached us within 100 yards.

We spent about 30 minutes with the whale before returning to port.

12pm:

On our next trip, we found one whale feeding in 85 feet of water. The humpback was originally found between Alcatraz and the Golden Gate Bridge. Over the course of the trip, the whale moved in between Alcatraz and Angel Island, then towards the Bay Bridge.

We saw lunge feeding and roll feeding from this animal. There were birds hovering over the spot where the whale was feeding.

There was tons of bait in the area, as well as tons of boats approaching the whales. There were inboard/outboard motor boats, sailboats, and large ships in the area.

We spent over an hour with this animal as it moved around the bay.

3pm:

On our final trip of the day we headed back out to the Golden Gate Strait, where we found two whales in about 117 feet of water. One of the whales was moving in and out of the strait, while the other stayed farther out.

We saw some fluke dives from the closer individual, who we identified in our catalog as #62. This whale had new scars on its fluke since we last saw it in 2018.

The whale was feeding, with birds and anchovies present in the same area. There were a few sailboats nearby.

We spent about an hour with this animal.

11am:

On our first trip of the day we headed down to Pacifica, where we found four humpback whales feeding close to shore.

The whales were lunge feeding in less than 30 feet of water.

We saw other evidence of feeding as well, including the presence of anchovies on the fish finder and a huge group of birds close to where the whales were. Three of the whales converged on the spot near the birds. They were lunge feeding probably in less than 20 feet of water.

After watching these animals for about 40 minutes, we started to head back to port. At that point we received a report that there was a humpback whale in San Francisco Bay.

As we approached the Golden Gate Bridge, we spotted the whale just ahead of us. We stayed with it for about 10 minutes, during which time we saw a fluke dive.

We were able to identify this whale as Black October, a whale named by our very own Captain Joe!

There were ships and sailboats passing by and a little bit of bait on the fish finder.

2pm:

On our next trip we headed back out to the Golden Gate Strait and found two humpbacks. First we watched the one near Baker Beach, which we identified again as Black October. We saw one breach from this animal, followed by some fluke diving. The whale appeared to be feeding.

The other whale was across the strait, but moved towards us over the course of the trip. We saw a fluke dive from this animal as well.

We spent about 45 minutes with these animals, who were feeding in 130 feet of water and making their way west over the course of the trip.

We saw some shipping activity as well as some sail and powerboats.

2pm:

On this trip we headed out into foggy conditions and found one humpback whale near the shipping lane. We were able to identify this whale as Akula.

We didn’t see any flukes from Akula, but we were able to identify her from her dorsal fin.

Akula was moving south over the course of the trip. She kept her distance from the boat.

We also saw some sea lions on the shipping lane buoys.

On this trip we found one humpback out past the pilot station feeding in 94 feet of water. It had been extremely foggy all the way until we were 12 miles offshore, when it finally started to open up.

The whale was traveling, so each time we spotted the whale it had moved farther west.

However, we did get to see two full breaches where the whale’s whole body came out of the water. These breaches were followed by a fluke dive which will allow us to identify this animal.

We also saw large groups of sooty shearwaters on our way in.

2pm:
On our next trip we were several miles west of the shipping lane when we found two humpback whales.

Although these whales took a long time to find, we were treated with a close approach where the whales came within 20 yards of our boat before fluke diving.

These whales were in 108 feet of water.

11am:

On this trip we found the whales close to buoys 7 and 8, right at the beginning of the ship channel. There were three humpback whales feeding in 55 feet of water.

The whales moved around and frequently doubled back, moving to both sides of the shipping lane. For the most part they stayed close together. We even saw one triple lunge feed where the whales were nearly touching each other.

We also saw other evidence of feeding, including fluke dives, single lunge feeds, and birds hovering over the whales.

Ships passed by us over the course of the trip. At first we delayed our approach across the shipping lane because of a large inbound container ship. We were able to alert vessel traffic to the presence of the whales and the ship slowed down.

At one point one whale came within 15 yards of our boat. This whale was separate from the group of three that we were watching. This whale appeared to be traveling; after its close approach, we spotted it again several hundred yards north of us.

Over the course of the trip the whales moved just over a mile east. These were some of the closest whales to shore that we’d seen in a while.

We also spotted sea lions on the shipping lane buoys. At one point the whales approached them as well.

We spent about 50 minutes with these animals.

2pm:

On our next trip we headed back out in the same area and found three humpbacks seven miles from our dock. Conditions had deteriorated since our previous trip, and the waves were steep with a short period.

One of the whales tail slapped for almost the entire trip. The whale changed locations, but continued to slap dozens of times.

We also saw several breaches from this animal.

The other two whales stuck together and we saw coordinated diving behaviors from them.

There was a ton of porpoise, bird, and sea lion activity in the area.

Near the end of the trip, we saw a sea lion eating what appeared to be a large salmon.

The whales were in about 63 feet of water and we stayed with them for 40 minutes.

9am:

For our first trip we headed 15 miles west, past the shipping lane. We had wet conditions on the way out due to a coastal southerly wind.

Once out there we spotted two humpback whales; one was closer to us, while the other was farther off. We paralleled the closer whale for several minutes as it travelled.

The whale was not feeding. No food appeared to be present in the area.

There was some shipping activity in the lane. We spotted some big splashes from the farther whale, suggesting that it was breaching.

12pm:

The whales were a little bit closer on our second trip, although the southerly had increased and the way out was very wet. We found three humpbacks in about 85 feet of water.

One of the whales was closer to us with a small spout. We observed this animal for several minutes before sighting the other two on the other side of the shipping lane.

We saw some fluke dives from these animals. We had anchovies on the fish finder and birds in the area, suggesting that there was food.

034A6500.jpg

We saw some inbound container ships. The two far whales swam directly in front of the ship before safely popping up behind it. Then they swam across our bow.

3pm:

By the final trip of the day, the conditions had improved and it was less wet than the previous trips. We returned to the same area, where we found three humpbacks in 107 feet of water.

The humpbacks were feeding, but moved around quite a bit as they did so.

One of the whales did a close approach on the stern of our vessel. As it came closer, we were able to identify this whale as Akula. This was the third time we had seen Akula this week.

We spent about 35 minutes with these animals before heading back to the dock.

Sightings from San Francisco Whale Tours vessel Kitty Kat

9am:

On our first trip of the day we found humpbacks whales about 14 miles offshore, close to the pilot station. There were nine whales in the area feeding in 100 feet of water.

We saw fluke dives from these animals, as well as lunge feeding. There was one coordinated lunge feed with two whales.

The whales in the area moved around a lot. Different groups were constantly moving apart and coming together.

There were birds hovering over the whales and anchovies on the fish finder. We stayed with the whales for about 30 minutes.

12pm:

On our next trip we found the whales several miles east of the previous location. The whales were near buoys 1 and 2, directly in the shipping lane.

There were four humpbacks feeding in 60 feet of water.

We saw fluke dives and some coordinated lunge feeding from these whales. Large ships and the pilot boat were nearby.

There were lots of birds in the area, particularly shearwaters. The birds were flushed from the surface of the water by the whales several times.

We stayed with these animals for about 45 minutes. There were another 2-3 spouts in the distance as well.

3pm:

On our final trip of the day we found one whale in almost the exact same spot, directly in the shipping lane.

After seeing a few spouts and getting a good look at the dorsal fin, we identified the whale as Akula - a frequent visitor to this area.

Akula wasn’t fluke diving, but after a few minutes she began tail slapping, allowing us to get a good look at the orca tooth rakes on her fluke.

There were anchovies on the fish finder and birds hovering over Akula, so it is likely she was feeding. We stayed with Akula for about 40 minutes.

There were ships present over the course of the trip. We also saw a large sunfish come down the side of our boat.

There were California sea lions on the shipping lane buoys as well.

Sighting from San Francisco Whale Tours vessel Kitty Kat

11am:

On our first trip of the day we headed far out west, past the shipping lane. We ended up about 15 miles offshore. There we found five humpbacks feeding in 150 feet of water. The water color was a dark purple-brown color, suggesting that the whales might have been feeding on krill.

We saw lots of interesting behaviors from these animals, including lots of feeding behavior. We saw lunge feeding, fluke dives, and some coordinated behavior from two of the animals.

The whales were spread out except for two who continually surfaced together.

There were birds hovering over the whales as they fed. We also saw a couple of breaches.

We could see fish in the water during the trip, including a mola mola.

We had excellent conditions. It was sunny with no wind and only a little bit of swell. We stayed with the whales for about half an hour.

2pm:

On our next trip we found two humpbacks feeding a few miles east of their earlier spot in 166 feet of water.

We saw more coordinated activity from these two whales, including a couple of double lunge feeds. We also got fluke dives from these animals.

As we floated in neutral, one of the whales approached within 50 yards of our vessel. It swam around our stern, then rejoined the other whale 150 yards west of us.

When they reunited, one of the whales began breaching. It did full breaches twice, followed by 2-3 chin slaps. Some of the chin slaps were almost like half-breaches.

We spotted some water draining from the whale’s baleen during the chin slaps. Sometimes the whales open their mouths when excited, so it might have been draining out water that got in during the excitement.

The whales in this area were definitely feeding on anchovies. We spotted a few bait balls in the area. We also had lots of shearwaters present - both sooty and pink-footed.

We also saw a huge mola mola on this trip.
