July 13 and 14 – Weekly Census

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.
  • See the photo gallery below for more ecological happenings from the past two days.

Here are photo highlights from the past two days. Click on the photos for larger views and captions.

Census, elephant seal D018 returns

Weather: wind mostly westerly averaging 30 to 40 k/hr sunny most of the day

Visitors: no boats braved Race Rocks today, after the storm yesterday the swell was still big, the wind strong all day and the tidal variation caused fast currents

Addendum: at around 8 pm a ecotourism boat came through for a beautiful sunset run. Cold and windy but clear.

Census,

 

Although not the ideal day for the census as the winds were still very strong and I think the lack of small birds may be due to that, no sparrows, no turnstones and no shorebirds, but Greg is taking over from me and he will have his hands full doing island maintenance so I thought I would help out in this way.

Elephant seals 6

A large male (compared to the 3 young ones on the island) showed up today. His tag reads D018 and he has been here several times. The last record I can find of him is 2020. But he did come in 2019 and 2018. I have contacted Patrick Robinson and look forward to hearing more of his history. A small female also arrived. Her skin is in bad shape. I believe it is more than moulting but we can see how she fares the next few days if she stays around.

D018

Newly arrived small female with skin condition

Gulls  421

Seals 66

California sealions 17

Stellar 10

Canada Geese 14, currently 3 active nests

Pigeon guillemots 136

Cormorants 34

River otter 1 on the grass by the crane

It was a mid day low tide of .4 metres. The westerly was strong and there was some swell. The tidepools and spring seaweed growth were phenomenal. Here are a few pictures.

Census and censured

Weather; beautifully calm most of the day. Sunny with the occasional cloud. Wind mostly southwest

Visitors to reserve: 1 kayaker at slack tide. Went around seal rocks. Caused a landslide of Stellar sea lions.

No eco-tourism boats. Maybe the whales were in a different area?

Work: finished cleaning the lamp room and started sweeping the lighthouse stairs. chopped wood. what kept me VERY busy was the energy system which was drawing 2 kW instead of 1.2 kW (our usual load). I spent several hours trying to find something using that much draw. I had to start the generator at about 6 a.m. as the battery voltage was very low (large draw continued all night). Then I thought running the desalinator might solve the problem but neither seemingly did. It continued drawing between 1.6 and 2.1 until 3 pm and then it went down to 1.2. Greg believes charging up the battery from the generator may have reset things?

Observations:

Census

Elephant seals 7 (the male juvenile was away for several days this week but is back on Great Race)

Stellar sea lions 51 on south islands, none on Great Race today but over the last week there have been one or two here

Oyster Catchers estimate 20

Harlequin ducks saw 5

Turnstones 32 very rough estimate, there are 8 on the grassy area around the house

Savannah sparrows I only ever see 4 at once but I see them constantly, that’s why I guess 20

Surf birds so well camouflaged but I would guess 20?

The following were seen this past week but not today,

Marbled godwit

Brown headed cowbird

brown headed cowbird

Sea otter

sea otter!

Birds I did not get a picture off but were here this week:

Northern Crow (today and yesterday, aggressively chased away!!)

Semipalmated plover x 1

purple martin x 1

 

CENSURED

it appears to me that the 6 moulting females may NOT be female. the 3 large adults appear female but the at least 2 of the 3 small may be male. Am I right?

Doesn’t this “female” appear male???

Here’s a female.

*40 knot winds and an extremely high tide likely contributed to the lower wildlife counts.
