Sightings Report: July 7th, 2017

All sightings from San Francisco Whale Tours vessel Kitty Kat


At around 2:30 we found humpback whales just outside the Golden Gate Bridge near Diablo CoveThere were 3 feeding in the immediate area, with more spouts sighted further out in the strait. 

We got a close look at a couple of harbor seals and 4-5 harbor porpoises off our bow. We also were treated to the sight of a California sea lion chowing down on a large king salmon. Several common murres were sighted with their mouths full of northern anchovies.


The wind had picked up a bit from the last tour, but we still spotted a few different whales pretty quickly, including one just outside the Golden Gate Bridge. There were lots of spouts on the horizon, so we headed out towards Mile Rock. At 5:50, we slowly and carefully positioned ourselves above the spouts and floated in neutral as a humpback whale roughly 120 yards away repeatedly slapped its fluke against the water. The sound from the slap can be heard from far away underwater; it has potential uses for communication, as well as scaring fish into a tighter school. The slapping humpback was missing a chunk of one of the lobes on its fluke, making it very distinctive and easy to recognize. Another 2-3 spouts were sighted further offshore.

There were 4-5 more spouts near Point Bonita moving in towards the bridge, and two more humpbacks between Mile Rock and the bridge. I estimated that there were at least 8 different whales sighted in the Strait.
