July 15 and 16 – A Scoop of Pelicans

Posted on by

Ecological Notes:

  • 12 brown pelicans flew around the island at 12:30 yesterday. They returned just before 14:00, flew by the South Islands, and landed on the South Seal Rocks. They moved to the east side of Race Rocks, where they remained for at least a couple hours. A group of pelicans is known as either a pod, pouch, scoop, squadron, or fleet.
  • The glaucous-winged gull chicks are growing quickly, with many meal deliveries happening throughout the day by their parents.

July 13 and 14 – Weekly Census

Posted on by

Ecological Notes:

  • The sea lion population is growing. For the past few days there have been 18 Steller sea lions hauled out on Middle Rocks. That is up from four sea lions one week ago. One of the sea lions has a brand. It appears to say 620R, although the researcher I contacted in Oregon mentioned it is what they call a bad brand and he was unable to determine the brand from the photos I sent. I will keep a look out for the sea lion and see if I can get a better view. The researcher will check his records to see if he can identify the sea lion and be able to record the resighting.
  • The super moon on Wednesday night rose in the southeast at 10:00pm. It was a big bright orange orb that looked more like the rising sun, than the moon.
  • Today’s extremely low tide of -0.2m or -0.7′ was at 10:13am. The overnight high tide at 00:55am was 3.0m or 9.8′. It is apparently the lowest tide in a decade. I was fascinated to see the extended edge of the water all around the many islands. I looked at the exposed intertidal zone from a distance and up on the jetty, so as not to disturb the many delicate species.

Census July 6

Posted on by

Ecological Notes:

  • I am seeing more gull chicks everyday. Many gull parents are frequently feeding their two or three chicks.
  • I seem to have come to an understanding with some gulls. If I approach near them on the path at a slow speed, we both ignore each other. There are other gulls who freak out if I even look in their direction. As I do necessary work, I limit my movements around the island and avoid certain paths that have nearby nests and chicks.
  • See photo gallery and captions for more details on the ecological happenings over the past two days.

Gull Chicks Everywhere

Posted on by

It is great to be back as the Ecoguardian at Race Rocks. I have been lucky enough to spend a total of almost seven months here between 2014 and my last shift which ended on September 1, 2020. I have been spending the past three and a bit days reacquainting myself with the island and infastructure. I have not stayed here before in July, so it is taking some adjustment to live in harmony and not disturb hundreds of nesting gulls. It drastically limits where I can go on the island.

Ecological Notes:

  • The glaucous-winged gull population is increasing everyday with lots of chicks hatching. I do my best to avoid getting close to the nests. I move quickly by the ones near doors and pathways on which I need to travel to get to the energy building, jetty and lighthouse.
  • A pod of orcas swam westward through the ecological reserve on Saturday, July 2, then went eastward in Race Channel. The orcas continued to head eastward, with at one point 14 ecotour boats viewing them from a safe distance.
  • A juvenile male elephant seal, tagged D018/D019, has been hanging around here for a while this spring and early summer. I noticed the tags this weekend, so I could confirm it was the same seal that Ecoguardian Joan spotted on the seal’s arrival on the island on May 19. Here is a link to the tagged resight histories, when I spotted this seal in April 2020 and reported the details to the Director of the Año Nuevo Reserve, in California. The brief version is he was tagged in February 2017 as a pup in Año Nuevo. He was first observed at Race Rocks in April 2018. He was again spotted here in April 2019, December 2019, and April 2020. His proboscis (nose) and body has grown a lot in the past couple years. I wonder what adventures he has gone on in that time.
  • I know of two black oystercatcher chicks that I have seen through the binoculars and  long lens of the camera. One is hanging out near the jetty with its parents. The other is hanging out near east bay with its parents. The dark grey fluff ball chicks are hard to spot, as they blend in well with rocks.
  • See the photos below for these and more ecological sights.

Weather:

  • The wind has been consistently coming from the west over the past four days that I have been here.
  • Friday and Saturday were part cloudly with lots of sun to fully charge the solar panels by 17:00 both days.
  • Sunday and Monday were overcast with periods of rain and fog.
  • The temperature in the past four days has ranged between 11 to 14 oC.

Visitors:

  • Greg drove the boat on the afternoon of Friday, July 1 to do the shift changeover between Jillian and I. Thanks, Jillian, for leaving the place in such great shape.

Vessel Traffic:

  • Many Canadian and American ecotour boats have been nearby throughout this long weekend.

Weekly Census

Posted on by

Wind: yesterday 8-33 knots S to W, today 2-24 knots W to NE
Sea State: rippled
Visibility: 10-15 NM
Sky: both days mixture of sun and clouds
Temperature: yesterday 3 to 8 °C, today 2 to 4 °C
Atmospheric CO2: 412.63 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The snow is melting quickly, bringing puddles and mud.

The one day old elephant seal pup appears to be doing well and nursing a lot. It’s moving around and wiggling more than the other two did in their first couple days. The alpha male has been mating numerous times with the mother of the oldest pup.

In the early afternoon, I wandered around the island and peered out from the top of the tower to count the mammals and birds. There were some notable omissions in this fourth week of conducting the census. I didn’t see any geese today. The only sign of the honking birds was a lot of poop and tracks in the snow. I also did not see any black oystercatchers. It is possible the birds were scared off by the loud explosions. The Armed Forces were blasting yesterday and today at the Department of National Defence land-based demolition range on Bentinck Island, the closest land to Race Rocks. Directly after each blast, I witnessed sea lions stampeding into the water and birds taking flight. According to a 2017 article On the firing line with the navy, in the Victoria newspaper Times Colonist, the detonation range is used for training members of the Canadian Navy on how to use explosives. The navy has apparently made efforts to lessen the effects on marine life.

Results of the weekly megafauna and bird census:
10 elephant seals (4 females, 4 males, 2 pups)
200 steller sea lions
242 california sea lions
107 harbour seals

56 brandt’s cormorants
124 pelagic cormorants
43 double-crested cormorants
178 Thayer’s gulls

The last two days were spent doing some tasks around the island like running the desalinator, topping up the batteries with the generator and cleaning. Today, the sun in the morning and early afternoon was taken advantage of to get a great view of all the species for the weekly census and do a solar powered load of laundry.

The only visitor was Greg, who came out from the college this afternoon for an hour to show me how to use some equipment and remove a load garbage from the island. No other boats were seen in the ecological reserve.

I am glad to hear the Race Rocks live video cameras are being used by the grade 10 students in the Trek Outdoor Education Program, in Vancouver.

First Weekly Census of the Decade

Posted on by

Wind: 5-21 knots N-NE
Sea State: up to 3 m waves
Visibility: 10 NM
Sky: overcast with rain
Temperature:5-11 C
Atmospheric CO2: 412.64 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The weekly census was done today, because the rain yesterday created poor visibility. This morning, it was overcast but not raining, so there was a good birds-eye view from the top of the lighthouse. Some species that were not last week are a whimbrel, snow bunting and another female elephant seal. The new seal looks pregnant, so there might be another pup very soon. She has moved into a spot on the grass between the desalinator building and the flagpole. That’s a great place for me to watch from the house, which is just 20m away. Last year, the three pups were born between January 4 and January 20.

I heard back from a sea lion researcher about the branded sea lions that were seen on Race Rocks a two days ago. Bryan, from the Oregon Department of Fish and Wildlife, let me know about some of the places where the sea lions have been:
California X282: branded at Astoria (Oregon) on Feb 25, 2016 and resighted in Oregon and at San Miguel Island, CA in 2016-2017.
California X392: branded at Astoria on March 8, 2016 and resighted in Oregon and at San Miguel Island in 2016.
California X501: branded at Astoria on May 24, 2016 and resighted in Oregon fall of 2016.
California 1-59: braded at Bonneville Dam (near Portland, Oregon on the Columbia River)on May 19, 2015 and resighted at Astoria and Bonneville through 2017.

The only boats seen in the ecological reserve were two eco tour boats and two kayakers.

January 3 census results:

6 elephant seals (2 females, 3 males, 1 pup)
223 steller sea lions
291 california sea lions
30 harbour seals
21 bald eagles (13 adults and 8 juveniles)
1 raven
103 brandt’s cormorants
16 double-crested cormorants
17 pelagic cormorants
264 gulls (most of them appeared to be thayer’s gulls)
36 black oystercatchers
18 harlequin ducks
1 whimbrel
15 surfbirds
28 black turnstones
1 snow bunting

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.

Boxing Day Megafauna Census

Posted on by

Wind: 0-25 knots NE
Sea State: up to 1 m chop
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.
