May 8

Although it started out from the north-northeast, for most of the day, the wind blew from the southeast. Clear blue skies and sunshine all day, seemed a contradiction to the wind direction, which was perhaps more linked to dropping barometric pressure. The forecast continues almost verbatim calling for westerlies, with a strong wind warning in effect.

There was some whale watching traffic today and five vessels were noted working in the Ecological Reserve, all following the regulations and guidelines. Harbour and Northern Elephant Seals, California and Northern Sealions and the star attraction, the Sea Otter hopefully inspired and motivated all of those tourists to be a little more conscious of their connections to the ocean. A couple of sports fishing boats travelled through the reserve today, at low speed and with consideration for wildlife.

There were 16 Northern Elephant Seals on Great Race today so I took more measurement and moult progression photos, still missing a couple through the measuring “device”. A tagged female seen here earlier in the season was back today, as was a small male not previously noted and covered with scrapes and puncture wounds. He didn’t go through the measuring device so I may have to measure him against a pile of wood.

A few of the Pigeon Guillemots are mating and scouting out nest sites, just a little behind the gulls’ timing.

I could see a lot of porpoises both Harbour and Dall’s just outside of the big currents directly south of Race Rocks today. They were probably a mile outside the Ecological Reserve Boundary.

Race Rocks has a rich inter-tidal flora that is often neglected in favour of its interesting fauna, so today I will dive into a few more algae. Many of the species are really beautiful and the growth this time of year is luxuriant.

Sexy Ulva

This two toned Ulva lactuca is going reproductive (aka sexy seaweed).

spongemorpha

Spongomorpha is a green algae with tiny little hooks that bind the strands together like dreadlocks.

costaria2

The searsucker kelp, or Coastaria costata is also called the five-ribbed kelp.

cymathere 2

Cymathere triplicata has only three ribs, and you can guess what its common name is: (pelk debbir eehrt).

 

nori2

This is one of the many species of nori found on the shore here. I am not sure if it is Porphyra or one of the new translations. The Whelsh name for it is laver.

smithora2

Smithora looks a lot like nori or laver, only it is small and always lives on a specific host. Here it is growing on surfgrass.

Odanthalia

Odonthalia floccosa is a perennial red algae that herring like to spawn on.

 

Constantinea is another perennial red. It grows like an umbrella with the  stipe (stem) in the middle.

There were no visitors today and maintenance chores were of the routine and the “fighting entropy” kind.

Killer Whales, Porpoise and Sea Lions Galore.

It was another glorious day at Race Rocks and the trend is continuing. The barometer rose slowly until late afternoon and then levelled off and dropped a bit. The forecast is for outflow easterlies that are so good at keeping the fog at bay.
Following a little too close.
There was a flurry of whale watching activity today as Southern Resident Killer Whales went past Race Rocks going east with the tide. After the main pod had passed, there were 15 whale watching boats in the reserve and I noted a total of 32 over the day.
Crowded in front of the jetty
I saw two Harbour Porpoise (Phocoena phocoena) feeding in the reserve. They are such smooth, quiet, little divers. They seemed to be feeding on some sort of forage fish that were flipping at the surface. Very tidy and well behaved compared to the sea lions.
Tide is coming up.
Some of the choice spots for hauling out are quite crowded now and there is a lot of jockeying for position in the California Sea Lion mosh pit where it is not unusual to see animals running across others to find a comfy sleeping spot. They stack in like cord-wood and must keep each other warm.

Here are a few shots of the California Sea Lion with the orange tags (no numbers) that has been ring-necked but seems to be healthy and vigorous. I didn’t find the ring-necked Steller’s today.
Stopped scratching for a moment.

Alex Fletcher solved my bird mystery: the mystery birds are Killdeer that arrive just after dark each night. Alex has heard them in the winter too. They must roost on the island and then leave for the day, as I have not seen them in daylight yet.

I finished the fence today, did more cleaning and made fresh water with the desalinator. By the time I went to turn off the generator the Sea Lions were laying on my fence. Hmmm, that is not not very effective.
