Gull Activity

Posted on by

Ecological Notes:

  • Only 2 Elephant Seals left. The largest of the Females, and the Juvenile Male, who is slightly large than the female. Glad(?) to see the last male pup move to the ocean, as he was getting very thin, and looked to be loosing energy. Hopefully He’s off to regain weight and start growing again!

Not too hungry yet, we like it here!

  • The Gulls have nests everywhere, and for the most part are pretty mellow, until an eagle or tern flies over. Every now and then they fly up behind me, but drop quietly if I turn and face them.

Visitors:

  • Shorefront coordinator delivered groceries and supplies yesterday.

Facility Work:

  • Oil and filter changes on the Generator. Service of batteries.

Generator, used only for short periods when there hasn’t been enough Solar power to keep the batteries up.

 

Noted Vessel Traffic:

  • 3 private vessels, short sightseeing visits.

Weather Events:

  • Westerly winds all day, 20 – 30 knots, rising to 35 – 30 knots late afternoon. Light fog in the morning, sunny and clear all day. Heavy haze in the evening, not quite dense enough to be called fog. Swells up to 2 meters, with 1 meter chop on top of that.

Business As Usual

Posted on by

Weather:

  • Visibility 15 NM
  • Sky partly cloudy
  • Wind 30-40 knots N
  • Sea state: white caps, fast moving water, waves and swells up to 1 m

Visitors/Boats:

  • There have been no visitors to the island and no boats within the reserve

Ecological:

  • There is a new goose nest with one egg so far established in the middle of the island where the footpaths intersect
  • The young pup has seemed particularly inactive recently, and we have not seen her in the water for some time. Nick mentioned to us when he visited that she seems to have gained weight so we are not overly concerned. She spends most of her time near the jetty behind her favorite fence post.
  • The goose with an injured leg continues to limp around the island, but seems to be making do and there are no signs of deteriorating condition.
  • The eagle activity has been steady, aside from today with these strong winds
  • The seagulls are beginning to pull the grass and collect other debris for nesting, but no established nests so far.

Maintenance:

  • The generator is still out of commission, but we have been taking in a substantial amount of solar energy. Combined with the smaller generator contributing, our batteries have remained healthy. We are conserving water heavily until the new part arrives, as the desalination process requires a sizable amount of electricity.
  • Felted sea lion fur
  • Goose down clinging to rocks
  • Abandoned goose nest behind fuel shed
  • E103, “Erica” enjoying the sprinkle from a punctured fire hose
  • Keeping the solar panels clean

Weekly Census

The numbers of sea lions continues to be low. For the first time this winter, there were more steller than california sea lions in the ecological reserve.

For the past day, the elephant seals have all been stationary. An elephant seal was seen on Middle Rocks today along with california sea lions. I believe it’s the smaller adult male that was on the main island until recently.

Having heard the killdeer on many evenings this winter, but not seen any, I finally saw one this morning on the lawn. They are named for their shrill repetitive call which sounds like “kill-deer!”

Here are the results from the weekly census observed on Friday, February 28:
7 elephant seals (4 adult males, 2 female pups, 1 male pup)
54 steller sea lions
53 california sea lions
86 harbour seals
5 bald eagles (2 adults, 3 juveniles)
26 Canada geese
9 brandt’s cormorants
10 double-crested cormorants
31 pelagic cormorants
72 gulls (mostly thayer’s)
8 black oystercatchers
66 pigeon guillemots
17 harlequin ducks
1 killdeer
15 black turnstones
6 surfbirds
1 fox sparrow

Yesterday, Greg, Alex, Warren and Cole were on the island to do maintenance on the desalinator and batteries. Two tour boats were seen in the ecological reserve each day. This afternoon, the RCM SAR boat from Sooke drove around the main island and the crew took photos.

 

Full Power Restored

Wind: yesterday 0-34 knots from N to W, today 18-36 knots from W
Sea State: yesterday calm in morning changing up to 1m chop, today chop up to 1 m
Visibility: yesterday 5-10 NM, today 10-15NM
Sky: yesterday overcast and rain, today clear changing to rain in evening
Temperature: yesterday 5-8 °C, today 6-7 °C
Atmospheric CO2: 413.81 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

After twenty-five days with backup power, there is now full power on the island. The replacement part for the generator head was installed today. Thanks goes to the team who spent six hours on the island today, hauling the 450 lbs unit from the boat to the generator room, doing the installation and other needed upgrades. It was a busy day here for Greg, Alex, Lawrence, Stephane from Frontier Power, Ric and his apprentice Stephane. Lots of other staff at Pearson College made it possible for this fix and temporary power to be successful.

With full power restored, there is now enough power to more quickly top up the batteries and operate all the equipment on the island without draining the batteries too much. A few important pieces are now running again: the desalinator, Ocean Networks Canada’s CODAR, UVIC’s Davis weather station and both live cameras.

There are still four male elephant seals and three pups on the island. There was some fighting amongst the males last night, evident by the fresh cuts on the backs of three of the males and near the eye of the youngest female pup.

The number of sea lions on the rocks has decreased in the past two days. It could be related to the strong west winds that blow into some of their favourite haul out spots.

There was one tour boat seen in the ecological reserve today.

DND was conducting demolition training on nearby Bentinck Island today.

Wind: yesterday 5-20 knots from W to N, today 0-40 knots from N to W
Sea State: yesterday rippled, today calm in the morning and up to 1 m chop in the afternoon
Visibility: yesterday 0-15 NM, today 1-10 NM
Sky: yesterday fog then sun, today overcast and rain
Temperature: yesterday 7-9 °C, today 8-15 °C
Atmospheric CO2: 413.95 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It’s been a mix of weather over the past two days. Yesterday began with the fog signal beeping. Later in the morning, it got sunny. It was overcast this morning and afternoon. This evening, it got quite warm up to 15 °C and wet as a storm came in from the west.

There were six ecotour boats in the reserve over the past two days.

Three visitors were on the island today to work on the generator. For at least the next few days, the island is still on backup power. The web cameras and several other non essential systems on the island will remain off to conserve energy.

See the photos below for some views from the past two days:

The five day old elephant seal pup died overnight. It was in rough shape yesterday, possibly from attacks by other elephant seals. In the morning yesterday, it had fresh blood on its face and the alpha male was lying on the pup. Ravens and black turnstones have been pecking at the seals face occasionally for the past day.

The first elephant seal pup, which is fending for itself now as a weaner, was lying on its back today and I could tell it was a male. See the photo below. I am not sure the sex of the other pups, as I haven’t had a good look at their abdomens.

There were four visitors to the island yesterday. Jeff brought out Greg, Alex and Ric to work on the power issues. They hooked up a backup generator to help power the island and top up the batteries. In the afternoon, Greg brought a diesel delivery. Now, the island has a full supply of fuel for when the main generator gets fixed within the next few days. In the past few days, there has a been some power generated by solar energy, which has helped keep the batteries charged. Thanks to some IT help from Dan at the college, now there is internet for the weather systems and monitoring the power.

Four eco tour boats were in the reserve over the past two days.

On Tuesday night, the first elephant seal mother left the island, leaving her 24 day old pup to fend for itself. The mother had the tail flipper tag T562. The pup is still hanging out with the harem on the lawn.

The island is running on reduced power due to an issue with the generator, which is in the process of being fixed.

Four eco tour boats were in the reserve over the past two days. There were no human visitors on the island.

See the photos below for a few sights from the past two days:

Fourth Elephant Seal Pup

The elephant seal harem has a new addition. In the early afternoon yesterday, another pup was born. Since December 29, there have been four births, which is a record for an elephant seal pupping season on Race Rocks. Unfortunately, only about half of pups tend to survive, due to aggression from other elephant seals, learning to nurse, weaning and predation.

There were three visitors yesterday to do some maintenance on the desalinator: Greg, Warren and Cole. Warren and Cole got a once in lifetime opportunity to see the elephant seal birth. They were walking from the desalinator building to the main house, when Warren noticed the pregnant seal had more flippers than usual. Within less than a minute, the female slid up a grassy incline and out popped the pup. It seems like she used gravity to her advantage. All the humans went into the house, so as not to disturb the seals. The new mother vocalized with the pup and the pup wriggled around. The pup appeared larger than the other three at birth. Perhaps it is a male, as male pups tend to be larger than female pups.

What followed next was difficult to watch. Just ten minutes after the pup was born, it was attacked by another mother. The elephant seal mother that gave birth to the third pup, tossed around and bit the new pup, drawing blood between the eyes and on the head. After a few attacks and several minutes passing, the new mother appeared to intervene and put itself between the aggressive seal and her pup. The mother that gave birth to the second pup also appeared to intervene, by approaching and also putting itself in the middle. Out of the five adults in the harem, the third mother was the only one that showed aggression towards the new pup.

Today, Alex and Greg visited for a couple hours in the middle of the day to problem solve a power issue that presented itself yesterday. It’s great to have a lot of people on land supporting the various off grid systems on Race Rocks.

Here are a few photos from the past two days of the flora and fauna on Race Rocks:

It has been mostly quiet on the rock for the past two days, with the exception of the sea lions barking nonstop. It’s a mystery to me what they carry on about all night. Although, I will take that any night over the fog horn or the urban noises that are too far away for me to hear. The only visitors to the reserve were a few eco tour boats that lingered offshore in the late afternoons.

I had to quickly jump into action this morning, when I realized power had gone out just before I got out of bed. I ran the generator for several hours to make sure the batteries were fully charged. The solar panels helped a bit today, soaking up 3.7kWh of energy, which is a couple hours worth of the energy used on the island. There is lots of learning about off grid living.

Yesterday one of the juvenile males elephant seals left, bringing the population of elephant seals on the island from six to five.

A parcel of about 20 oystercatchers have been hanging out on the south side of the island. They mostly huddle on one leg with their beaks tucked into a wing.

The northeast winds have delivered presents in the form of free firewood to heat the ecoguardian’s house. Through some clumsy use of a pike pole and the tolerance of a nearby resting elephant seal, I managed to land a 6.5 metre log and drag it up the jetty ramp. I also gathered lots of smaller pieces. The wood will be left out in the rain for a while to wash off the salt, then chopped up into manageable pieces, and eventually put away to dry for next winter.
