Pinniped Notes

Posted on by

Ecological Notes:

  • All 3 Adult Female Elephant seals have left the island, occasionally showing up late at night, bellowing from the high points of the island for a couple hours, then returning to the ocean. I wonder if they are calling out looking for males?
  • The 3 Elephant Seal pups have formed their own little pack and have been spending time”wrestling” and exploring the small standing fresh water pond. They also have been exploring the mud flats to the north of the house, looking out towards the water. In past years, they have followed adults down to the water via the boat ramp, but haven’t seemed to explore that way yet.

Meeting at the scratching branch

“This is our Ocean!” (not really, it’s just a mud puddle)

“The real ocean is out there….. but how do we get to it?”

  • Big Male Steller Sea Lions have pretty much taken over the prime area of rock by the crane shed. The largest each take their own rock, and are surround by smaller ones that look to me like females. Remembering that in December, I photographed 4 different females nursing young here at Race Rocks.

  • Female Steller nursing a pup!

A couple California Sea Lions in this one, but normally just big males Stellers and smaller Stellers (females?)

  • There are fewer California sea lions around, but there are reports of many hauled out at Trial Island, which has not been seen for many years.
