Sea lions are returning

Posted on by

Wildlife notes:

I returned after 10 days away to find two notable differences. The male elephant seal is not here and there is an explosion in the sea lion population. It seems every time I look there are more and they are coming closer to the electric fence. I thought the gulls had a lot to say to each other!  It will be interesting watching them. The weather is the same as when I left and I am back to wearing long underwear, sweaters and a toque.

Unlike the elephant seal, this California sea lion is using its hind flippers for scratching.

 

Facility work:

  • Cleaned solar panels
  • Topped up battery fluid

Vessels:

  • 25 Ecotourism

Weather:

  • Fog with visibility less than 1/4 mile in the morning, lifting by 12:00 and clear skies by 14:00. Strong westerly breeze most of the day. Near gale westerlies in the late evening. Daytime temperatures: low 11, high 18.

August 3 – Station Boat

Posted on by

The Race Rocks 14′ Boston Whaler boat has not been used in a while. After the elephant seals cleared the ramp for their post swim afternoon nap, I lowered the boat to the water with the electric winch. Once I made sure the motor was running properly, I took the boat out for a quick 20 minute ride, including idling to take photos and look in the binoculars. I had back up by VHF radio and cellphone in case anything went awry. Pearson’s boat Second Nature was in the area, taking alumni on tours around the Ecological Reserve. The station boat is running well. I look forward to more around the rocks tours over the coming weeks. I do need to troubleshoot the GPS/SONAR unit before I go out next. Oddly, it was working fine in the boathouse. Race Rocks would be boring if everything worked all the time.

The sea lion population continues to climb with 60 on Middle Rock and 13 on Great Race by the jetty. That is a big difference to yesterday afternoon when there were no barks or belches coming from the main island, just the occasional elephant seal bellow or sleep apnea snort.

I will contact NOAA and DFO to report the resighting of the California sea lion with the tag 13-2. The orange tags mean the sea lion was rehabilitated. The tag on the left flipper means the sea lion is a male. I will update the log when I hear back about his history. The rest of the California and Steller sea lions are currently hauled out on Middle Rocks. Perhaps this guy needs a break from the frat party.
