Blowing a Hooley

Posted on by

Wind: Yesterday 5-35 knots N to W; Today 25-35 knots W with gust of 44 knots
Sea State: up to 2.5 m waves
Visibility: 5-10 NM
Sky: overcast with clear patches today
Temperature: 7-12 C
Atmospheric CO2: 413.20 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The forecasted gale warning materialized right on time on Tuesday evening. Overnight and throughout today, the westerly winds were between 25 to 35 knots with gusts as strong as 44 knots. There are lots of whistles and creaks in the 1960’s house. The storm also showed a few leaks in the various outbuildings. The strong winds brought clear skies and slightly warmer temperatures. For most of the day, rainbows were visible to the north, between Rocky Point and Victoria.

Yesterday, even though it was stormy, several hours were spent working outside on various maintenance and month end tasks around the island, which was made easier due to the animals and birds being less spread out as they hunkered down out of the wind.

Today, four branded sea lions were recorded and reported to researchers, who study sea lion ranges and lifespans.

The island’s population of elephant seals is currently at seven. One recently came back from a solo retreat on the West Rocks. The four non dominant males appear to be keeping their distance from each other at cardinal points of the island. The alpha male is hanging out in the middle of the island with the mother and pup. This morning, two of the beta males had fresh wounds on their backs, suggesting a possible disagreement with each other overnight. The elephant seal pup is continuing to nurse. Pups gain a whopping 4.5 kg per day from their 35 kg birth weight. Between all those pounds the pup is packing on and the rain, no wonder its coat is looking less wrinkled.

One Day Old Elephant Seal Pup

Wind: Yesterday 5-15 knots W to N; Today 0-18 knots SW to E
Sea State: up to 1 m chop
Visibility: 10-15 NM
Sky: overcast with light rain this evening
Temperature: 8-9 C
Atmospheric CO2: 412.75 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The one day old elephant seal pup is doing well. It seems to have got the hang of nursing. The alpha male elephant seal, who in the past has been referred to as Bernard, interacted with the pup and mother several times today.

I heard from elephant seal researchers in California that the new mother is T562, who also had a pup on January 4, 2019 on Race Rocks. She was born in the 2010-2011 breeding season on SE Farallon Island, near San Francisco. Until the beginning of 2019, she hadn’t been recorded anywhere since her birth. See Garry Fletcher’s post from February 9th about the elephant seal cow.

Last breeding season, three elephant seal births occurred between January 4 to 20. I will keep a look out for more elephant seal arrivals. Usually, they haul out and then give birth a few days later. Although, the new mother T562 was here for a couple weeks before she gave birth.

The entangled california sea lion is still present on the rocks near the winch and jetty. There has been no sign for the past two days of the entangled steller sea lion.

A previously rescued california sea lion was spotted today and appears to be doing well. More can be read about the care given to that sea lion during the visit by the Marine Mammal Rescue Centre, as detailed in Laas’ post from November 9.

Several eco tour boats have been in the reserve each evening. Yesterday, SCUBA divers were in the water near the North Rocks.

Here is a video of the new elephant seal family:

Boxing Day Megafauna Census

Visibility: 15 NM
Sky: overcast with sunny patches throughout the days
Temperature: between 6 to 7 C
Atmospheric CO2: 412.28 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

This morning, I heard a ruckus outside the west side of the house, where the a few of the elephant seals have been hanging out. The largest male appeared to be fighting the small juvenile male, while the female watched. The adult was slamming its head down onto the juvenile and biting it. This lasted for a few minutes before the juvenile and female fled to the north side of the path.

While I was doing the census in the middle of the day, there were three people snorkelling off the southwest of Great Race Rock Island. They took turns snorkelling in pairs, while one person stayed in the boat. Six other pleasure craft and eco tour boats were seen in the reserve over the past two days.

Shift Changeover

Wind: 0-20 knots NE
Sea State: 0.5 m chop
Visibility: 15+ NM

Atmospheric CO2: 412.73 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday, Laas’ shift ended after being on Race Rocks for the past two and half months and a big chunk of the past two and a half years. I came out to the island at noon on Second Nature with Guy, Corey, two students, a family visiting the college and a friend of Laas. It was great to share in the excitement of all on the boat. I also appreciated their help carrying my many bins of food. I always get excited when the boat rounds the corner out of Pedder Bay and the lighthouse comes into view. The cacuphony of seal lion barks and belches was overwhelming when the boat pulled up to the jetty. Thanks for the great welcome home, my pinniped pals. I had a run through of the energy systems with Laas, Guy and Corey, as the equipment has changed completely since I was here almost five years ago. It’s great to be back on the Rock. Thank you Laas for leaving the place so tidy. Best of luck on your new adventures.

After the group left, I climbed the 99 steps inside the lighthouse to get a bird’s-eye view of the island. I spend the rest of the day reacquainting myself with the place and unpacking. I welcomed the slow down, as I settled into the island that I will call home for the season, watching the changes as the days become longer. I will be here for all of winter and depart soon after the vernal equinox.

Today, I continued to check out more places and do the regular tasks like monitor the energy levels, wash the solar panels, turn the composting toilet and sample the salinity and temperature of the water at high tide. On one trip up the lighthouse, I counted 336 sea lions on the rocks. There are also six elephant seals on the main island: three large males spaced apart from each other, one pregnant looking female in the centre of the island and two juvenile males.

sick California sea lion

Posted on by

Yesterday I spotted this sea lion when I was clearing the jetty

Today he looks worse. He is lethargic and thin. He does not ambulate normally. I did contact the marine mammal vet but I am not hopeful there is anything to be done. I am wondering about the diagnosis. Is there such a thing as a fractured baculum? I noticed online that genital cancer is a diagnosis in marine mammals.

There are over 1000 sea lions here and most look amazingly robust. it is expected that there will be disease and I noticed on this blog that many pictures of ill animals are posted. As this is my first time coming to stay here I was overwhelmed by the many many posts of sick, injured and neck banded sea lions. It is heart breaking but now that I am here and wrestling daily with the feisty beasts I am relieved that the posts, although necessary, certainly do not represent the majority! That is why I have added a sunset picture!

 

 

 

 

 

A Quiet Week

Posted on by

Weather: 

  • Sky blue, a few clouds
  • Visibility 15+ miles (less fog lately)
  • Wind 20-30 knots W
  • Water choppy, waves to .5 m, whitecaps

Boats/Visitors:

  • No visitors to the island since Greg delivered water on Monday. We were happy to have a few guests of the college also stop in for a visit at the same time.
  • Lately there have been quite a few eco-tourism vessels (20+ each day). The noise from the vessels is continuous and can be felt as a low vibration even inside the house. We have seen the odd private pleasure craft as well but they are typically smaller and move more slowly.

Ecological: 

  • The seagulls are growing more and more! The chicks have started to flap their wings into the wind, and wading into the water near the jetty. The adults seem to be attacking the young less frequently as they get bigger, but we still spot the odd deceased chick. Today we saw an adult gull swallow an unlucky chick whole.
  • The oyster catcher chicks have begun flying! They are able to cross the short distance between the jetty and the nearby rocks.
  • There are only two moulting male elephant seals on the island now. They look like they will likely leave soon, as their peeling of skin and fur is nearly done.
  • Earlier this week we saw orcas in the reserve, making twice in the past week and a half.
  • There have been a handful of seal pups and their moms resting in the shallower intertidal on the SE side of the island (also many seals on rosedale rock)
  • There has been a slow increase in sea lions hauling out onto west and middle rock. They occasionally stop on the jetty at a higher tide, or the rocks nearby.

Seagull chicks growing and adult seagulls less aggressive

Posted on by

Weather

  • Visibility: 15 miles
  • Wind: 25-35 knts W
  • Sky: Clear
  • Water: 1-2m waves, white caps
  • Some fog this morning to the south

Birds

  • The early seagull chicks have grown a lot, and are currently 2/3 the size of the adults.
  • Today was the first day the seagulls seemed to be (relatively) less aggressive – not sure if it was because of the strong wind or the fact that the chicks can now move themselves to safety.

Marine mammals

  • The californian sea lion that was earlier seen near the guest house, has returned there.
  • Saw a female elephant seal on the island after a while. That makes 3 males and 1 female on the island
  • I think there are more than 2 harbour seal pups near the island, although I haven’t been able to confirm yet. Attached is a picture.

  • Quite a few ecotour boats in the area today, especially in Race Passage

Bird Notes

  • The first set of seagull chicks are growing fast – one of the first things to develop are long legs. I spotted some of them flapping their wings in imitation of the adults, but they are still a long way from flying.

Mammal Notes

  • A lone sea lion made it all the way up on the main island until the guest residence! It would get aggressive if I got even slightly close to it. I first thought it might be injured, but I saw no scars or bleeding anywhere.
