Animal Notes and Census

Posted on by

A few days ago we had two unusual visitors to our waters. Two Brown Pelicans (Pelecanus occidentalis) spent several days on Great Race and North Rocks. Brown Pelicans, though the smalles of pelicans, are enormous birds weighing up to 6 kilos and measuring up to 135 cms with a wingspan of up to 2.5 meters.

We have had two other unusual visitors in the last week. I discovered a Barred Owl in the boathouse attacking a Starling (another recent arrival), and Pam our avid photographer friend from England got several pictures of Peregrine Falcons that came through hunting sparrows and starlings. Pam’s pictures can be seen at: http://www.flickr.com/photos/66339356@N00/sets/72157628747376295/

Another tagged e-seal showed up in the boathouse yesterday.

Might as well hang out somewhere cozy…

Early November finds us at the end of the Sea Lion occupation of Great Race Rock. There are perhaps only 50 or 60 remaining in the Reserve and they have moved back to the smaller offshore islets. And though I shall miss them I admit to feeling some relief that the 7 weeks of the cacophonic onslaught is over! Never would I have imagined that I would have lived so close (almost under) a posse of Steller and California Sea Lions and have the opportunity to learn their ways. But it is also a bit lonely/solitary again; the misty grey days of November, the enveloping fog banks, glassy swells rolling up the Strait… there is something a bit ethereal about the whole experience living on the edge of the world.

A half dozen young Elephant Seals continue to occupy Middle Rock with random forays over here. Yesterday there was a little fellow in the boathouse, and a new individual with a pink tag!

Many visitors have been dropping by including Pearson College Director David Hawley and his advisee group for a weekend, and a visiting group of trustees from a UWC school in Germany. I am puttering away at a few maintenance projects, keeping the energy and weather systems functioning, and cleaning up after the Sea Lions. They have coughed a pink, fishy mucus all over the white walls of the buildings and it dried and adhered in the late September sunshine. A charming souvenir of their stay!

 

More coming soon….

Back on the Rock

Posted on by

Well it is good to be back on this beautiful little island, though the 100 California Sea Lions cuddling under my window are a tad boisterous and noisy. More arrive everyday…

Dozens of California Sea Lions around the house

The Steller Sea Lions tend to congregate on the south side of the island near the engine room. They truly are magnificent creatures, sort of the equivalent of an ocean grizzly bear. In fact I think “lions” is a misnomer and we should call them “Sea Bears”. What do you think?

Currently 5 young elephant seals are making good use of the boat ramp. Word is getting out amongst the species that this is a good place to relax and to get your picture on the Internet!

Perhaps because it is Labour Day weekend and the weather is so nice, there are lots of boats in and around the reserve. Sadly quite a few violate the rules about fishing or speeding in the reserve and unfortunately there is little I can do, except wave or gesticulate at them. Launching my boat is rarely an option, unless I want to disturb the elephant seals, and the boats that are speeding are long gone… As much as I dislike signage, we might be wise to post “No Fishing” and “5 knots” signs to alert the ignorant. It is hard to blame someone who doesn’t know the guidelines.

Many thanks to Julie who worked diligently over the summer to maintain the infrastructure and keep a close eye on things. She is off to southern climes for adventure and learning.

Guardian Changeover

I am making final preparations for my departure tomorrow and Mike’s return. The past two months have been very enjoyable being surrounded by the wildlife here and beautiful landscape.

The sea lions seem to be occupying every side of the island except the jetty. The right image is the rocky shore to the East of the house, the centre is the south side of the island, and on the right is West Race Rocks.

 

 

We now have 5 elephant seals on the island, although no big males have returned.

The past two days have been overcast and there was a light drizzle today. Sure makes for a beautiful sunset, though!

The return of the elephant seals

Elephant seals (on left is 8 foot female)

Over a week ago the last elephant seal had departed so I was surprised to see a new untagged seal arrive August 23. Since then, two have joined it and they all appear to be female. I recognize none of them and the larger one I measured to be nearly 8 feet long. The 3 don’t appear to have been fasting either and the 8-foot female in particular is quite large.

The new Glaucous-winged gulls born in late June are now flying all over the place and their parents are far less protective. The two pictured are the same from my earlier posts.

On a different subject, the island’s bird calls have been almost completely replaced by the sea lions’ barking now.

The sea lion numbers have grown and since August 21 have gradually moved from the jetty to the rocky shore on the East side of the island.

Marine mammals and vessels

Stellar and California sea lions near sunset

The sea lions have moved in! Last night more than a dozen spent their first night on the main rock. Around sunset there were over 20 on rocks across from the jetty and in close waters. About 50-75 are still camped out on North and West Race Rocks.

I’m unsure if it is a coincidence, but the sea lions’ arrival was directly after the elephant seals’ departure. Although there are still 3 juveniles on site, our 2 alpha males and half dozen other seals haven’t returned since Saturday, 4 August.

On another note, a Canadian Coast Guard vessel was tied up to the Rosedale Reef buoy on the edge of the reserve yesterday for a couple of hours late in the day. It’s the first time I’ve seen the buoy being used since my time out here.

On Sunday 37 whale watching boats entered the reserve as well 3 private boats. It’s a lot of activity for such a small area and I wonder about the effects it has on the wildlife. A new 2-deck whale watching ship of Orca Spirit Adventures has a capacity of 200 passengers. I can’t help but think the noise pollution created by this vessel that advertises its indoor dining area and dance floor does harm to the very animals they are in search of.

Seal Pups and traffic

Posted on by

Harbour seals are frequenting the kelp beds regularly with their new pups. I have spotted a half dozen pups so far. Harbour seals (Phoca vitulina) are most often found in estuaries and shallow bays but here in the reserve there are approximately 35 right now. They feed at hide tide and rest during low tide usually somewhere within the south-eastern part of the reserve.

Marine traffic has increased significantly this week. Today, whale watching boats alone exceeded 40 in the reserve and there were around a dozen private boaters as well. In the last post I mentioned the whale tour boats are well mannered though unfortunately speeding between North Race Rocks and Great Race Rocks has become much more common in the past week.

There is a count of 9 elephant seals at the moment, which dropped from 11 earlier in the week. Some, like Misery (our largest male), seem to spend equal time in water and on shore now.

Also, 3 groups of student visitors came out on Monday, Tuesday, and Wednesday for tours to learn about the reserve, its importance, and to get a peek at the elephant seals. The tours were kept brief as to not disturb the gulls who are still rather anxious to protect their young.

 

21 July Update

Posted on by



Today I scrubbed the tank room door with TSP (grease cleaner/remover) in order to paint it. Because it needs time to dry I decided to go and sand down the jetty in preparation for its paint job. In the short span it took me to do so our elephant seal friend managed to worm its way halfway into the tank room from ~10 metres away… Again!

After some prodding it finally manoeuvred out of the doorway. Although it seems rather humorous, this incident raises more serious questions about measures we will have to take in the future if the elephant seal population continues to rise.

The jetty, for example, which is the most preferred spot for water entries and exits, is hardly large enough to accommodate the two adult males we have here as it is.

 

Also, an update on the progress of the 3 chicks shown left. Many chicks on the island are starting to show signs of trying to fly.

A different 3 have decided to block my doorway for the past week or so.

Yesterday Chris Blondeau came to clean camera 2 (the underwater camera) and there were six other visitors who toured the island.

 

Elephant seal encounters

Posted on by

The elephant seals have had some funny encounters with some of the other animals on the island. There have been some close calls between the seals and the gulls, though I’m not sure on whose part.

 

 

 

 

 

On their way to and from the water each day, the seals cross over bird nesting areas (which are hard to avoid on the island). Recently they have been visiting the water more often so this is becoming a larger problem for the gulls who frantically call in defence of their young. I must say they put up a good fight. The above shots show two gulls who, while attacking Misery, dare to land on his back to distract him and deter his path. It made for quite the stand off.

Chunk with Sea Lion

The elephant seals have also been interacting with the sea lions more, who have been hanging around the jetty more frequently. Unlike the gulls, the sea lions (both Stellar and California) happily share the space. Yesterday when docking the boat there was a sea lion on the boat ramp amidst 4-5 elephant seals in the water and on the ramp. However, if confronted the sea lion knows who the alpha male is and makes for a quick depart, as this one (pictured right) did just after the photo was taken.
