Cackling goose and Snow goose

Posted on by

Light Wind in the morning, String Westerly in the evening. Cloudy with scattered showers. Rain in the evening. Tour boats:8 1030 flyover by a small float plane The Cackling Goose and Snow Goose (note — a new record for Race Rocks ) are still foraging on the grass on Great Race. The Canada Geese often chase these two smaller geese. The Sea lions all moved to the East side of West Rocks this morning. Up until today, they had been on South Rocks since I got here in the middle of March. Eagles are regularly flying over Great Race and making all the Gulls take flight, but I have yet to see an Eagle grab a Gull.

Morning fog. Moderate East wind. Sunny the rest of the day.
Tour boats: 4

It seems that, as the sea lions are leaving, more gulls and birds are moving onto Greater Race Rock. There have also been a lot of dense groups of gulls and diving birds on the water in and around the reserve.

The juvenile elephant seal with scabby molt (aka ‘Cranky Pants’) has returned to the boat ramp. Her skin has healed up a bit since she was last here a few weeks ago.

Animal Notes

Posted on by

A single, juvenile Greater White Fronted goose (Anser albifrons) arrived a few days ago and has been rustling around the middle of Greater Race Rock. This species was also documented at Race Rocks on May 2012, May 2007 and September 2007. Thanks Ann for verifying the species.

At the end of September a juvenile elephant seal was on the jetty for roughly a week. It had the classic signs of a scabby molt. Scabby molt is a skin disease that attacks elephant seals between the ages of eight months and two years old. Two-year-old elephant seals often suffer from a skin disease known as the northern elephant seal skin disease or NESSD for short. This form of dermatitis is also often referred to as scabby molt. This ulcerative skin disease can either infect a small portion of the fur and underlying skin or spread to cover up to 60% or more of this outer protective layer. Although, in most cases, the elephant seals heal up without any further problems, sometimes, secondary bacterial infections and/or sepsis can lead to death.

Check out this link to a paper by Beckamn et al, 1997 that describes this disease.

Female Elephant Seals

Posted on by

The elephant seal population has been steadily declining over the past few weeks.  For the last few days since Jan 19 there have not been any female elephant seals visible in the reserve.  This is the time when elephant seal pups have been born out here in the past so it is somewhat surprising and a bit disappointing.  Both male elephant seals have been back and forth between the main island and West rock and have been chasing and trying to mount the few small females that have been around, which is likely why they have all left.

Elephant Seal Moulting

Posted on by

Race Rocks is at the northern limit of distribution of the Elephant Seal. They often number from 2 to 3 large males and 4 or 5 females. Arriving in January, they usually stay through the summer on the middle island and then leave for several months in the winter. Elephant seals often undergo a juvenile moult on the local beaches of Victoria when several years old. This individual may be at the end of such a moult as it still has a few sore spots on it’s coat. They end up on beaches where they wallow in the sand to keep the flies off. Members of the public often report them to the “authorities” as being diseased in appearance as their skin is blistered and raw. There has even been an example in the past few years in the local Victoria area when an animal in such condition was reported to the authorities as sick and due to ignorance, the animal was shot by an animal control officer. Of course this outraged some of some local residents who had been observing it for weeks as it was going through the moult, but the mistake had been made. So humans — leave well enough alone. Misguided intervention is not helpful for this rather rare pinniped

The video of this female elephant was videoed off the South side of Race Rocks. It was done in hi 8 – before we had SONY cameras that would record in Digital. One can see the patchy skin typical of the moulting stage just behind the head. This seal had probably already gone through the most serious part of the juvenile moult, which may have occurred on one of the sandy beaches over near Metchosin. The barking in the background is from California sealions. 

Slash, a year and a half after recovery

Posted on by

Slash, the elephant seal was struck by a motor boat at Race Rocks in January of 2003. Fortunately he has recovered well in the past year and a half as can be seen here in two videos taken by Mike Slater in July and August of 2004.

There is also a second video showing Slash undergoing a moult in August of 2004.

Moulting Elephant Seal video

The video of this female elephant was taken off the South side of Race Rocks. It was done iby Alex Fletcher in hi 8 – before we had SONY cameras that would record in Digital. One can see the patchy skin typical of the moulting stage just behind the head. This seal had probably already gone through the most serious part of the juvenile moult, which may have occurred on one of the sandy beaches over near Metchosin.
