Two Branded Sea Lions

Posted on by

Weather

  • Visibility: 15 miles
  • Wind: 15-25 knots NE
  • Water: 2′ chop
  • Sky: clear

Ecological

  • Spotted two northern sea lions with brands on them. The bigger one seemed to have 76Y branded on it, although the “7” was a bit undefined. The smaller one had three circles branded on its side. I assumed this was a brand, although in one of Anne Stewart’s log posts she mentions “cookie cutter shark scars” so perhaps this sea lion has three of those in a row?
  • Chunk and Chuckles spent the day in the same positions as yesterday.
  • Sadly, the weaner elephant seal on Middle Rock seems to be deceased. When I looked over there this morning I saw 8 bald eagles and blood stains all over the rock. I assume that one of the males killed it in the night. The body must have washed into the water.
  • With that death, we are now 0/4 at Race Rocks with elephant seal pups for 2016; 1 pup killed accidentally and 3 weaners killed on purpose. Killed for what purpose we do not know.

Maintenance

  • Stacked more firewood today.
  • Hauled some very large logs off the ramp. They seemed like small boats.
  • Had some troubles getting the YSI to turn on, so I took the sea water samples the old fashioned way first, before finally getting the YSI to work.

Boats

  • No boats in the reserve today.

March 21 – Scaffolding and a Turkey Vulture

Posted on by

Light rain and partially cloudy in the early morning; sunny for the rest of the day
Wind: W 6-27 knots
Air Temperature: Low 8.4°C, High 11.4°C
Ocean Temperature: 8.8°C

The visiting group of students toured the island and helped run the desalinator. In the afternoon they did a leadership initiative of setting up two levels of scaffolding and scrubbing the algae from the west wall of the Marine Science Centre. They did an amazing job of looking out for everyone’s safety and cleaning the walls.

A turkey vulture was seen in the early afternoon hovering by the Eco-Guardian’s house. It flew north towards Bentinck Island. They are rarely seen here at this time of year. Occasionally they pass through in the fall, on their southern migration routes.

There were two eco tour boat seen in the reserve today.
