Sea Lion Madness

Posted on by

Since the gale on Saturday night, about 75 Steller and 150 Californian sea lions have been hanging out under my window in the shelter of the house. It is hard to describe just how loud and smelly it is. I wish you could witness it for yourself! Well you can at: http://www.racerocks.com/racerock/video1frame.htm

Here are a few pictures. The Steller bulls (Eumetopias jubatus) are particularly impressive. Some of them weigh in at 1000 kgs.

Sea Lions are extremely social and appear boisterous and argumentative. Smaller individuals will always move for the bigger ones, though they roar, growl and hiss in protest. Clashes are very frequent but damage is rare. Most of the contact actually involves just the whiskers (vibrissae), though nips to the skin do happen. Usually a smaller one will snap back in defence then lurch away across the backs of the sleeping neighbours who lazily complain til the commotion stops and they drift back to sleep. 30 seconds later it happens again… all day long and most of the night too!

Back on the Rock

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?

Steller Bull congregation

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!

Young Elephant Seal

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.

Mike’s Last Day

Posted on by

I am off for the summer and Julie will be taking over, keeping a watchful eye over the animals and encouraging the public to maintain respect for the their well-being by motoring slowly within the reserve and maintaining a comfortable distance.

Same three gull chicks taken earlier

The big news of the last few days is the birth of numerous Glaucous-winged Gull chicks. They look adorable for the first few weeks with their leopard spots! Let’s keep our fingers crossed that the parent can find enough food for them to thrive.

These two pictures of the chicks were taken 24 hours apart. In the first you can see the egg-tooth of the emerging chick.

 

 

 

Mad Momma

The Gull parents are quite protective. I have had my hat knocked off and felt their warm white rain a few times… Last night I got splashed in the eye, much to my discomfort and annoyance. I’m sure there is a poetic justice to the experience though; at least from the Gull’s perspective!

June 26th Update

Elephant seal in workshop

Hi, I’m Julie and I’m going to be taking over for Mike starting in July. Over the past week and a half he’s kindly been showing me the ropes of the place. More elephant seals have been visiting and currently we have about ten in the reserve. A couple of days ago, one crept into one of the buildings where we take the salinity measurements. He stayed for a number of hours and seemed very pleased to have found himself a cool, shaded, and sheltered area.  Fortunately, he left on his own accord and no damage was done. Mike and I will be sure to keep a closer eye on the doors in the future!

Basking Chunk

Our largest male, Misery, has alas begun to moult and has lost a significant amount of pelage in the past day and a half. Chunk, our second largest, has been losing weight and we predict he will take off and return to the sea in the next few days.

 

 

On another note, the red flags were put up on Bentinck Island yesterday morning and there have been 4 blastings today by the military. Although the elephant seals don’t seem to be bothered terribly, the hundreds of glaucous-winged gulls go haywire each time this happens before settling back down again.

Yesterday, Mike spotted humpbacks passing south of the reserve in the rain.

Bird Notes

Bald Eagle on Gosling Carcass

The nesting gulls continue their vigil over their eggs. Oystercatcher couples furtively watch over their scrapes located just above the high-tide line, while Pigeon Guillemots incubate their eggs within the cracks and fissures of the rocks. Ironically the blasted rock, remnant of Coast Guard efforts to create more level terrain has provided habitat for them! Caspian Terns remain in the area but have not been noticed to land on the island. Cormorant are seen in the local waters but none appear to be nesting on the island this year.

Canada Geese

This season 4 pairs of Canada Geese hatched 20 goslings; a concern for us as this species that is not native to the West Coast can be quite destructive to some habitats. So far though they have had little effect on the grass (most of which is also introduced), and to date 10 of the goslings have been predated by eagles and ravens.
The West wind has stopped for a couple of days; a big relief and an opportunity to do some work that requires still air. Climbing ladders and cleaning the tower camera for example. I think we managed to solve the problem of intermittent outages of Camera 5 as well.

A New Mammal on the Island!

Julie has arrived! She will be taking over Eco-Guardian for the summer, keeping a close eye on our animal neighbours, monitoring human activity in the reserve, and doing the maintenance and upkeep required to keep the station running. I will be training her over the next few weeks.

Hungry Red-tailed Hawk

In other news, we had a visit from a Red-tailed Hawk (Buteo Jamaicensis) a few days ago.

I was lucky enough to capture this action-shot as it swept overhead.

June continues to be rather dismal and cold. Temperature has averaged about 12 degrees Celsius here with a high of 15.2…. pout.

 

 

 

 

The Boys are Moulting

Juvenile Male and lighthouse

There has been a bit of a gender shuffle in the local elephant seal population. Only one female remains, finishing up her moult but several young males have appeared in their stead.

Chunk Beginning to Moult

This corresponds to what is reported in the literature. Misery has just the slightest pelage loss while Chunk is much further advanced…

  • April to May – Females and juveniles
  • May to June – Sub-adult males
  • July to August – Adult males

Metallic Coast Guard debris

 

I have been removing copper and lead debris from the foreshore and intertidal zone where the Coast Guard dumped them many years ago. Ignorance led to many unsound practices in the years proceeding the new environmental ethos. Both lead and copper are biocides and should not be left to leach into the beach and water.

 

 

 

 

 

 

 

 

 

 

 

 

 

Animal Census First Sea Otter at Race Rocks

Things have been fairly quite lately regarding birds and mammals here, though one of the eco-tour boats reported seeing a Sea Otter (Enhydra lutris) in a kelp bed on Monday! The percussive blasts from Rocky Point military testing range scared off most of the Sea Lions last Thursday and only a few have returned in the last couple days. A large pod of orca passed through and near the reserve on Tuesday. Thanks to Suna, Doris and Ishmael for the census.

Caspian Terns

Posted on by

Caspian Tern, June 11, 2012

I have noticed several (2-6) Caspian Terns (Hydroprogne caspia) in the area for a month or so. They have proven very challenging to photograph but I got a couple good shots this afternoon. It is the world’s largest tern with a length of 48–56 cm, a wingspan of 127–140 cm. The global population is about 50,000 pairs. They have a distinguishing croak that sounds a bit like a Great Blue Heron.

Black Oystercatcher Eggs June 10, 2012

I also finally found an Oystercatcher nest just above the high-tide line on the West side of the island below the engine room.

 

Explosions Don’t Belong Here

Posted on by

I am rather annoyed to put it mildly. The military base at Rocky Point, an ordinance training facility is responsible today for about 10 of the loudest explosions I have heard since being here. The windows shook, and I could feel the percussion in my chest. As a result all the sea lions appear to have left the reserve, and half the juvenile elephant seals made for the water. The military has a huge piece of land so why do they have to practice on the beach of the incredibly beautiful Bentinck Island directly across from the reserve? If they need to practice why can’t they do it inland where the noise and pollution can be contained? Who are they accountable to? Besides the disruption it causes to animal life, it also means there are no animals for the tour operators to share with their clients. In other words we all lose.
