Visitors:
I drove the Race Rocks station boat to pick up a friend, who came for the night of July 18. Brad had visited Race Rocks before when we both worked for many summers on campus as coordinators for PSYL (Pearson Seminar on Youth Leadership).

July 11 and 12

Ecological Notes:

  • I believe most of the gulls eggs have hatched, based on the nests I can see with one to three chicks and discarded empty eggs nearby. The gull parents feed fish to their young. I am impressed how many whole little fish a gull catch then regurgitate for their chicks.
  • I am seeing more nursing harbour seals and pups around the south and east sides of the island. Today, I heard a pup communicating with its mother by little grunting sounds.
  • This afternoon, out of the corner of my eye, I saw a river otter scurry along a path by Tank Shed. I could not see if it was heading for the water or underneath the boardwalk, as they are elusive.
  • See the photo gallery below for more ecological happenings from the past two days.

Weather:

  • Yesterday (July 11):
    • Sky: Clear
    • Wind: W 1-33 kts
    • Sea: rippled, then 2′ chop in evening
    • Temperature Low 11oC, High 20oC
  • Today (July 12):
    • Sky: Clear, fog between 08:45-09:30 with foghorn
    • Wind: W 16-39 kts, gusts up to 44 kts (81 km/h)
    • Sea: 1′ chop in morning, then up to 4′ waves in afternoon and evening

Visitors:

  • Yesterday, Greg came from the college to refill the diesel tank.

Facility Work:

  • Scrubbed and squeegeed solar panels, routine tidying and checking infrastructure around the island. With the clear days, the solar panels have been fully charging the batteries.

Vessel Traffic:

  • Many Canadian and American ecotour boats have been nearby and heading through the waters of the ecological reserve. There were much fewer boats today, with the high winds.

Three Weaner Elephant Seal Pups

Wind: yesterday 2-15 knots from E to N, today 3-10 knots from S to N to E
Sea State: yesterday and today rippled
Visibility: yesterday and today 15 NM
Sky: yesterday and today clear
Temperature: yesterday 5-7 °C, today 5-8 °C
Atmospheric CO2: 414.73 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The past two days have been sunny, which means the animals and scenery are very photogenic.

There was lots of activity with the elephant seal harem today. Overnight, the third mother left the island, after nursing her pup for 24 days. Her pup is now a weaner, no longer getting milk from her mother. The three mothers whose pups survived all stayed for 24 days. The last female, who’s pup died 17 days ago, left late this morning. After the male mated with her, she was either trying to get away from him or was chased down the path and out into the water by the boat ramp. The alpha male left for about an hour, perhaps to get some food. He’s been on the island the longest of any of the elephant seals. He hasn’t eaten or left the island since before the first pup was born on December 29. That’s almost as long as I’ve been here without leaving, except I eat three meals a day. The female elephant seals will most likely return to Race Rocks exactly eleven months after they left, to give birth to another pup. Stay tuned to the Log next December and January for more pupping season drama.

Now that there are no adult female elephant seals left on Race Rocks, the alpha male’s role has changed from mating with the females, to protecting the three pups that remain. The alpha male is most likely father to all of them, as he was the alpha male last year as well.

Three beta male elephant seals are still on the island. One left for about 24 hours and returned this afternoon. When he slid up the ramp onto the island, he appeared to look around to see if any females were around. Then, he headed for the oldest pup and put his mouth around it. He didn’t appear to be trying to hurt it because no blood was drawn. The pup was screaming. The alpha male came over and scared away the beta male. For the afternoon and evening, the three pups were lying in the grass about 10 m away from each other. It will be interesting to see if the pups interact with each other, as they have in previous years.

Some other interesting sights were a sea otter, two black brant geese, and a very bright Venus visible in the western sky for a few hours after sunset for each of the past three nights.

There were no visitors to the island in the past two days. Four pleasure boats and three tour boats were seen in the ecological reserve.

End of Shift

The wind blew from the northeast at 13-26 knots.  A small swell with whitecaps blew in from the northeast.  The barometer dropped from 1024 hPa to 1015 hPa.  The temperature reached a high of 5oC at 15:00.

There were no boats seen within the reserve today.

Everyday there appears to be fewer gulls and sea lions in the reserve.  An official count will happen on Thursday with the census.  There are still a lot of cormorants congregating on the shores of Great Race, as well as Turbine Rock and North Rocks.  The harbour seals are hauling out at low tides on various rocky ledges close to the shoreline.

Today was filled with cleaning and wrapping up some tasks that I’ve been doing while here for the past five weeks: construction in the basement of the Marine Science Centre, sorting out photos, and cutting up firewood that was collected at the shore and piled up by the tank house to get the salt rinsed off by the rain. Tomorrow is a shift change that will see Alex arrive for the winter shift.  I’ve had a great time as the Ecoguardian, learning lots from the species and history of this beautiful piece of land and sea.
