September 1st Eco-guardian Log

It was a fairly quiet, dark and damp day at Race Rocks. The wind had still not done much by 18:00 but it rose out of the west later on blowing 20 – 25 knots. Although the ceiling was generally much higher than yesterday, solar radiation levels remained low, compared to the rest of the week, including stormy Saturday. The barometer dropped a little today, but remained above 1005 hPa and the forecast is for strong afternoon west winds to also bring much needed precipitation until Friday.

The weather pages on this racerocks.ca web site have lots of good data. If you like graphs or if you would like to learn to like graphs, check out the weekly solar radiation data graph to see how dark it has been lately.

It was another busy day for commercial whale watching activity in the Ecological Reserve with 17 visits observed. The main concerns were with a couple of vessel operators who are in a hurry and speed up before exiting the reserve. I really enjoy watching the better operators. They take their time; use the current to enhance their visit and make sure that their clients have a good experience, while assuring a sustainable future for their industry in the Ecological Reserve.

Four groups of Pearson College students visited the Ecological Reserve today as part of their orientation week activities. They were in the two vessels Haiku and Second Nature.

More sea lions appear to be arriving daily and I look forward to doing the census later this week. I have also documented a number of branded and tagged sea lions and data that will be shared with NOAA biologists. Today there were two Northern Elephant Seals on the island, the young male from the ramp yesterday moved up behind the boathouse and a similarly sized individual arrived on the ramp today with a crowd of California Sea Lions. Only one Elephant Seal was visible on Middle Rock, surrounded by Stellers Sea Lions.

Other less welcome arrivals were ~24 Canada Geese. I guess now that there are a few green shoots again; they are here to eat them. There is still a family of five, whose goslings were late to hatch, that looks like it hasn’t left yet.

I was busy with minor chores today, including the usual plus repairing the jetty fence twice, cleaning the camera, running the generator to bring the batteries back up and assessing generator use, de-salinator hours and various fuel quantities on hand for month end. I did make time to take a few photos and have included them in a gallery for your viewing pleasure.

Cool and Wet

The cool, wet weather these last couple of days at Race Rocks was a long time coming and the ceiling is still thick enough so that peak solar radiation levels are about half the norm for this month. The little bit of soil is sucking up the moisture and there is already some visible return of green, a colour almost defeated by the drought. The wind didn’t do much until late afternoon today and there was no wind most of the morning. By early afternoon it was up to 10 knots southeast, only to fall off again as it swung to a feeble southwest in the evening. The barometer continues to crawl out of the hole created by Saturday’s storm and it is almost back up to 1010hPa. From the forecast, it looks like periods of rain will continue as the cold front moves southward over the next few days and then we will be back into the summer pattern of westerly winds and possibly sunshine, if not fog.

There was quite a bit of whale watching activity in the area today. There were 18 visits made by commercial boats operating inside the Ecological Reserve and more outside. All but two vessels abided by the rules, taking it slow, being respectful and courteous to each other and mindful of the large concentration of animals in this protected area. From the radio chat and observations, I was able to ascertain that there were both Biggs’ and Southern Resident Killer Whales in the vicinity. Both pods passed just outside the reserve heading west about a half mile to the south. There was also a humpback feeding just east towards Victoria.

One, large, whale watching speeder may have taken his cue from the only “sports”-fishing boat that came into the reserve today. A Grady-White-type boat with halibut gear, came inside behind a line-up of whale watchers and then roared off from inside Middle Channel as if his urgency trumped the wildlife values in this congested area. Later one of the well respected companies had a large vessel observed taking off at speed after a visit to the sea lions, closer than 100m. I hope the animals in the water were able to get out of his way.

There were a number of sea lions with major wounds noted today and I will try to photo-document them on a drier day. Of note were fresh, severe gashes on at least three Steller Sea Lions and what appeared to be propeller marks on two Californians. Most of the sea lions spend their time sleeping when they are not off foraging or tussling with each other. The Californians that are awake though, are always barking.

I tried to document three branded California Sea Lions today but only succeeded in recording one full number without question, # 8228 on the left side. I got one partial # U_05 on the rump and another partial #U14__. I didn’t see any branded Steller’s yet.

The pre-summer cast of avian characters, is back and it is really a privilege to be here again to witness Race Rocks as the change to autumn happens. I saw at least 95 Black Turnstones busy foraging all over the island today. They roost together on the south shore in the evening, making it easier to get a good count . They are back from a summer away at nesting sites along the western Alaskan shores of the Bering and Chukchi Seas. Cormorants probably didn’t go far but the Double-Crested Cormorants I saw today definitely do not nest in the reserve.

Most of the Glaucous-winged Gull chicks have fledged and left the island but there are still a few slow pokes who are busy begging from worn-out looking parents for food. Amazingly some adults are feeding three big chicks that appear larger than the adult. There is evidence of fresh predation on these young gulls and River Otter is the prime suspect as it seems to be nocturnal or crepuscular activity and one of the remains was dragged right in to the otter den entranceway. As was noted last year, it appears that the head of the gull is enveloped in its neck skin as if the skin was torn and pulled up like a turtle-necked sweater coming off inside out.

A newly fledged Glaucous-winged Gull still not confident enough to fly away on a new adventure.

The Northern Elephant Seals surprised me. I knew there was one here on the marine railway ramp on Great Race because Guy and Christine had mentioned it and it hauled out just before they left yesterday. It is a really well fed young one, completely plumped out since I last saw them after their horrendous moulting fasts of the late spring. Another five Northern Elephant Seals are visible with the scope from the top of the tower, on Middle Rocks amidst the sea lions. Of the five, one appeared to be very small, perhaps young of the year and the other four were larger juveniles perhaps including a small adult female. I will try to get a better handle on this in the days to come.

There were no visitors today as I got back into routine chores and was constantly reminded of the incredible natural setting that makes this place so special.

Flying geese and no more elephant seal.

West wind- 15 knots early- Forecast 25 on the afternoon – visibility 10 miles clear.At 5h30 Guy saw the family of 5 geese coming flying back from a trip somewhere.I was speaking about rough times between those gulls: we found out that one chick got a broken leg and I guess with small chance to survive. Finally we could go ashore and when we came back the elephant seal was not on the island. She left 2 days ago on the 5th so pretty sure she left too for good. End of the season for those nice companions!The seawater is getting colder under 12 degrees and the salinity around 32. Air is cool too especially in the morning between 14 and 15 degrees and less if it’s foggy

A Californian Sea Lion on the railway

Nice weather, almost no wind and very sunny We were expected more wind and it came but late in the evening and raised to around 30 knots. Like usual it was a west wind.
Floyd and Chunk have not been in sight for a while now I would say that Floyd disappeared 7 days ago and Chunk 5 days ago. The little one left 3 days ago. The 2 big one were at that time really slim and it would be not surprising if they would be gone for good. Just the new young female is still around and yesterday we had the surprise to find this little elephant seal (in the rocks) closed to female Californian seal taking a nap on the railway. She was very curious of us and it was really a pleasure to spend time looking at this so gracious animal. She stayed there for at least 5 hours because she was just at the same spot when we came back for the water sampling. We really had to go on the jetty and she couldn’t handle to have us just above so she softly glided in the water.
At the same time closed to the jetty we were the witnesses of the first bath of a gull chicken. Nice! And on the other side you could see 2 beautiful shorebirds called Ruddy Turnstone easy to identify. Lot of life is going on around.
From the eco guardians house windows in the morning I could count 87 chickens. Now they are big enough and are not anymore closed to their birth spot. Actually they are really everywhere and on the high rocky spot too. At date we found 3 dead bodies of young gulls. The last one was on the stairs of the house.
Those days we had a lot of whale watchers around, closed to 20 each day.

July 24th to 26th:Calm weekend

On Friday we had our first rainy day. When we came back from town the rocks were not so white. Everything around looked cleaner but the smell at around 50m from shore was the same unique strong mixture of crab shrimp and fish. On Saturday a nice and cool day many boats around 50 were fishing in the strait along the Canadian coast.

Those days the number of elephant seals on Race Rocks is not stable. The 2 big ones have been away since the 23rd and the 2 young females come and go. Maybe they will be all gone pretty soon. lately the 4 of them didn’t go far on the island and used to rest closed to the boat shed going often back and forth to the water.

No visitors.

 

July 20th : A new resident

Just around 9 in the morning we saw a new female elephant seal. She was bigger than the small one already there. We were just pleased. It is so interesting to watch them. The sea lions are now closer. A dozen of them were on the south side of the Rock and some Californian one are on the middle Rocks. Many newborn harbor seals spend their energy playing in the water.
The wind never stopped rising from 33 knots around noon to almost 40 knots around 2PM. This situation kept us inside for the rest of the day.
Early in the morning we saw the big rescue boat going slowly. A few maybe 3 or 4 whale watchers came. It was a beautiful sunny day and the sea a gorgeous sight.
We were expecting visitors from the college but no way it was really too windy to tie to the dock.

Nursery Island

Nursery island

It was still 20 knots when we awake but the rest of the day was pretty calm from 15 knots to 22 at the most. What a change! We could see very far that day…

After so much wind we were not alone outside enjoying a normal summer day. ..We could call the rock “Nursing Island “because chicks are really everywhere and the gulls are pretty nervous never stopping between feeding the young one and watching out for danger. No way to go around without your yellow helmet like a big bill on the top of the head! Those birds hit you once but not two times and it hurts! You remember!

We had another show from Chunk and the young female in the water. She really wanted to please him! Even after weeks we are still amazed by those attaching animals. They have lost a lot of weight and are now pretty active spending a lot of time in shallow water and each time going back and forth from water to a grassy spot.

 

Desalinator and generator have been on for a few hours. Everything is working perfectly.

ANIMAL CENSUS

July 9th Thursday: Animal census

The fog was still there pretty thick but around 11:30 it cleared up and we could go up the tower to do the census. We had a west wind and the forecast was a gale warning for the end of the afternoon.The wind at noon was from West at 24 knots and could go to 35 in the late afternoon. We saw a few Whale watchers boats around noon and we had no visitors. Water is getting colder under 12 degrees Celsius. Guy put a new VHF on the whaler.

The estimation of the population is:
Elephant seals: 3
Sea Lions: 180
Pigeon–guillemots: 80
Gulls: 450 (yesterday we could see a group of gulls with black winged maybe some west gulls)
Pelagic cormorants: 3
Geese: 11 (Today the smallest one of the family of 5 was not in the water swimming but looked lost alone in the island hanging around). They spend more and more time in the water.
Black oystercatchers :0

Bald eagle: 1 (they attack the colony almost every day once in the morning)
