Farallon Islands Whale Watch Sightings: May 20, 2017

By Chris Biertuempfel

Upon departure from the dock on our May 20th Farallon Islands whale watching trip, our captain spotted a lone humpback whale deep inside San Francisco Bay, near Sausalito, setting the stage for a great day! The morning fog restricted our visibility to just a few hundred yards, but we were still able to spot another humpback just west of the Golden Gate Bridge.

As the tour continued toward the Farallones, the fog lifted and we saw a tall, columnar blow off the starboard bow (right front) of the boat. Upon closer investigation, it was a single blue whale moving slowly northwest. This whale surfaced a few more times, providing fantastic views before diving out of view. We then continued on, and in a short time reached southeast Farallon Island.

The islands were alive with bird and sea lion activity. With the sun out and great visibility, we identified a dozen species of seabirds, including Tufted Puffins and Red Phalaropes.

As we circumnavigated the islands, we came across a mottled gray whale near Seal Rock. The whale surfaced several times before exposing its fluke to passengers.

After the gray whale sighting, we briefly viewed a group of northern fur seals in the water near Maintop Island before we continued toward the continental shelf drop-off a few miles past the Farallones. On our way to the shelf, we came across a humpback whale with a distinctive notch in its tail that dove repeatedly.

While this whale was in view we also came upon a host of seabirds including numerous Pink-footed Shearwaters and several Black-footed Albatross, like this one gliding above the swell.

After an extended viewing of the albatrosses and a few more humpback whale sightings, we began our journey back to San Francisco. Reports were coming in of whales located right outside the bay. As we made our final approach we saw one humpback off our starboard (right side) with China Beach in the background and another humpback directly between us and the bridge. It was a great day!
