Weekly Census

Posted on by

Wind: yesterday 0-15 knots from E to S, today 0-10 knots from E to N
Sea State: yesterday and today rippled
Visibility: yesterday and today between 10-15 NM
Sky: yesterday cloudy with periods of rain and sun, clear overnight, today cloudy with periods of sun
Temperature: both days 7-10 °C
Atmospheric CO2: 414.08 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

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.

10 elephant seals (3 pups, 3 adult females, 4 adult males)

Weekly Census

Posted on by

Wind: yesterday 15-46 knots W, today 3-14 knots W shifting clockwise around to S
Sea State: yesterday up to 2 m waves, today rippled water
Visibility: 10 NM
Sky: yesterday overcast, today mainly sunny
Temperature: yesterday 6-7 °C, today 3-5 °C
Atmospheric CO2: 413.56 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

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.

Weekly megafauna and bird census results:
7 elephant seals (1 pup, 3 adult females, 3 adult males)
262 steller sea lions

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

Annual Christmas Bird Count

Posted on by

Wind: Yesterday 5-10 knots W; Today 5-20 knots NE
Sea State: up to 1 m chop
Visibility: 10 NM
Sky: overcast with rain this afternoon
Temperature: 7 C
Atmospheric CO2: 412.60 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

December 28 is the annual Christmas Bird Count, which happens in thousands of locations across North America. It has been happening for twenty-two years at Race Rocks. This morning with the northeast wind and dropping pressure, the planned visit by the local bird enthusiasts was called off. But fear not, citizen science provailed. For an hour and half this morning, I searched for birds of all feathers as I walked around the island and looked out from the top of the lighthouse. I used binoculars, a spotting scope and the zoom lens on the camera to check out the shoreline, water and the rocky islets of the ecological reserve. I was able to spot 12 species of birds, some of which were not present when I did the weekly census two days ago. Here are the results and photos of the bird count:

25 bald eagles (5 juvenile, 20 adults)
1 fox sparrow
4 canada geese
2 ravens
6 harlequin ducks
208 double-crested cormorants
59 pelagic cormorants
281 thayer’s gulls (on the rocks and in the water)
48 mew gulls (near Turbine Rock and North Rocks)
18 surfbirds
42 black turnstones
4 black oystercatchers

Photos of some of the birds seen today:

In the past two days, I have seen two entangled sea lions. Yesterday morning, I noticed a large steller sea lion with a small rope around its neck. The rope appeared to be cutting into the underside of the animal’s neck. A short while later, I noticed a california sea lion with a cut on its neck from what appears to be a plastic strap wrapped around it. The Marine Mammal Rescue Centre and Department of Fisheries and Oceans have been notified. If the sea lions remain at Race Rocks, it might be possible for a rescue to occur. Both animals were seen again today. See the entangled sea lion and marine mammal rescue tags for past occurrences that were written about in the Log. Two other california sea lions were seen that appear to have healing wounds from something that was previously wrapped around their necks. The animals don’t appear to have tags on their flippers to signify they have been rescued.

The Canadian flag was looking a bit tattered, so I replaced it today.

Just before sunset today, there were four eco tour boats in the reserve. The boats were all close to each other, which usually means something interesting is nearby. Sure enough, a pod of five or six orcas were passing westward. They travelled along the north side of the ecological reserve, just south of Bentinck Island and the Department of National Defence base.

Here are some photos from the past two days:
