9am:

On our first trip of the day, we spotted a humpback whale near Mile Rock in 167 feet of water.

Over the course of the trip, we followed the whale as it slowly moved east with the tide.

When this whale fluke dove, I was able to identify this whale as #72 in our catalog. 72 is also known as “Crazy Ivan.”

We also spotted other wildlife on this trip, including harbor seals.

We also had lots of bird activity in the area.

12pm:

On our second trip we found two humpback whales in the same spot. One of the whales was #72 “Crazy Ivan,” the same whale from the morning trip. We were seeing fluke dives from these animals.

For the first portion of the trip, the whales stayed a few hundred yards from our boat. However, after watching them for a while, one of the humpbacks decided to come close to our boat.

We saw a couple of roll feeds close to the vessel.

There was lots of bird activity in the area, including feeding Caspian terns.

3pm:

On the final trip we found two whales feeding in the same spot, near Mile Rock.

They moved in large circles close to the rock as they fed. There were large groups of cormorants and other feeding birds nearby.

As the trip went on, we started to spot a third spout outside the Golden Gate Strait. At one point, one of the whales approached within 100 yards of the boat.

We saw some fluke dives from the whales on this trip, so we will be able to identify which individuals we saw.

We also spotted other wildlife on this trip, including harbor seals.

There was also a large amount of bird and porpoise activity, including parasitic jaegers chasing terns.

11am:

On the first trip of the day we headed out west in sunny, beautiful conditions. As we were heading out, a crew member spotted a tall dorsal fin back behind us. We slowed down and were able to relocate a minke whale.

The minke surfaced several times near us, usually taking a few breaths and then going down for a deeper dive. There was also a huge group of sooty shearwaters in the area.

After watching the minke for a few minutes, we headed farther west and found two humpback whales near the entrance to the shipping lane.

The whales were displaying a variety of feeding behaviors, including lunge feeding, roll feeding, and fluke dives.

There was another whale farther out in the shipping lane as well. We saw a barge pass by us. Several small fishing boats were also working in the area.

The whales slowly moved east over the course of the trip.

We saw lots of bird activity in the area, including several brown pelicans.

A baby harbor seal popped up right in front of us at one point!

2pm:

On our second trip, we found whales again near the beginning of the shipping lane. There were three feeding whales within a thousand yards of us; all three were within the shipping lane.

The shipping lane was extremely busy, with several inbound and outbound ships passing by us over the course of the trip.

Over the course of the trip, the three whales came together near the south side of the shipping lane.

The whales were feeding close by to the ships. We saw lunge feeding, roll feeding, and some coordinated behaviors. One whale rolled onto its side to feed over and over again for the entire trip.

We saw one fluke dive over the course of this trip.

We kept a distance from the whales while the large ships were present. Several of the ships slowed down as they passed by the whales.

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.
