First Weekly Census of the Decade

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.

Annual Christmas Bird Count

Temperature: 7 C

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:

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.
