3 concrete rings

On December 29, 2012 I was looking at the winter erosion effect on the First Nations Burial Cairns. On the largest  Cairn, three concrete rings appeared which have never shown up before, since they have been covered with vegetation.

Here is the 2011 version of the mound:

And below are the concrete rings after heavy geese grazing and erosion has bared the top of the mound: Currently we can only guess that they were added since construction of the lighthouse and were perhaps used as a marker or base for an antenna.

Dec 24th

Have had some really nice weather out here since the storm. Pelicans are still stopping in and flying through the reserve, mostly in pairs or singles.  Bald Eagles have been quite active in the mornings hunting.

 

On top of the crane, the eagle had just finished eating what looked like some part of a seagull.  In this picture the eagle’s nictitating membrane is covering the eye.  According to Baldeagleinfo.com, “every three or four seconds, the nictitating membrane slides across the eye from front to back, wiping dirt and dust from the cornea. Because the membrane is translucent, the eagle can see even while it is over the eye.”

A few nights ago Zeke got some fresh wounds on his back from Misery, it was not as bad as the the last time.  Him and Misery have been on the main island for several days now. I have not been seeing as many female elephant seals since the storm.  

On Dec 19 there were 15 Green Winged Teals in a pool on the NE side of the island.  This  is the first recorded sighting of this bird in the reserve.

 

 

There has also been a Mallard duck in the reserve for over a week.  Pam Birley first sighted it around Dec 18th, it was also the first recorded sighting of this bird in the reserve.

 

 

 

Yesterday after sunset a lone adult orca passed through the reserve going over Rosedale Reef.

Green-winged teals: Photo by Alex Fletcher, Dec 12, 2014. Alex noted that they seem to come after the heavy rains as they did last year.

Below  is the first set of image taken of Anas carolinensis, the green-winged Teal at Race Rocks.

Ecoguardian Alex Fletcher took this first set of images of green-winged teal ducks at Race Rocks in December 2012. 

 

These ducks are common over on Vancouver Island but we have never recorded them out here before.

I suspect it was because there were many freshwater ponds on the lawns with the heavy rains recently on the island.

Storm

 

Westerly swells near middle rock, Northern sea lions surfing.

Storm damage to roof of Science Centre building.

On Dec 16th in the afternoon a low pressure system moved in right over southern vancouver island bringing Easterly winds that exceeded 50 knots (measured from tower) and then switched 180 degrees, within a few hours over midnight, to Westerly winds toping out also over 50 knots the morning of Dec 17th.  As shown above atmospheric pressure reached a low of below 980 hPa, one of the lowest readings i have seen out here.

Flying sea lion

The westerly winds brought several dumps of hail and rain and created good surf conditions for Northern sealions to catch a few waves. Several shingles were blown off the Science Centre building on both the  South and North sides of the roof.

Race Rocks Sponsors 2012

DONORS:
The Hesse Family:
 Mr. and Mrs. Hesse of Metchosin have been long-term enthusiasts for ornithology. They decided to help us with our Race Rocks Program in 2003 and 2005 with a generous donation to the program. They have both passed away now but have left a generous legacy to the College Race Rocks Program.

Dr. Anita Brinkmann-Voss : has provided long-term scientific support and yearly financial assistance to the racerocks.com program.

 

Lester B. Pearson College is one of ten United World Colleges located around the world. Two hundred students from over 80 countries study the International Baccalaureate curriculum during their two years at Pearson College. Garry Fletcher, a former faculty member who taught Environmental Systems and Biology at Pearson College, volunteers as the the educational director of racerocks.com, and webmaster for the website. Garry still works with students and staff to guide the educational content of the site. In addition, Laura Verhegge, also a faculty member teaching Biology and Marine Science provides additional guidance to the program. Pearson College operates the former Race Rocks light station facilities as a education centre under an agreement with BC Parks. Chris Blondeau, the Director of Operations for Pearson College provides the Operational Management of Race Rocks. A job-sharing arrangement in order to provide an employee of Pearson College as the on-site Ecoguardian is supported by Lester B.Pearson College which is the lead proponent and partner directing the racerocks.com project.

TELUS has been a major supporter of the racerocks.com since its inception. This link provides the history of our long term relationship and dependence on TELUS.

Apple Learning Interchange The QuickTime live audio and temporary portable video streams are being hosted by the Apple Learning interchange over the Akamai Internet distribution network.

In the design of the Race Rocks Taxonomy central index file, I have been able to rely on the freely available JavaScript DHTML code supplied by Andy Wooley of Milonic. The availability of such free assistance on the web has been essential to the building of that taxonomy.

Pelicans

A couple of California sea lions (dark) and Northern sea lions with 3 pelicans and an elephant seal in the background on west rock Dec 13

Pelicans have been in the reserve again Dec 13 and 14th.  There were up to 5 individuals, I was not able to see tags on any of them.

It is impressive to watch these birds, especially in flight.  They apparently have a wingspan of 6 to 8.5 feet.  They glide within what looks like a couple of feet of the water so when they flap their wings the tips will often touch the surface.
