A trip with BC Parks Staff to Race Rocks

On the morning of Wednesday June  6 , I went with Andy MacDonald,  the Vancouver Island Region (South) Parks and Protected Areas Section Head, and  Zsana Tulcsik, the new BC Parks Area Supervisor from the Goldstream Office out to the Race Rocks Ecological Reserve. ( A report by Garry Fletcher, Race Rocks ER warden)

College staff member Erik Schauff skippered Second Nature and we met Chris Blondeau , Director of Operations for Pearson College UWC  on the jetty. He is the relief ecoguardian at  Race Rocks for the week .

The elephant seals co-operated and were basking in the sun on the grass in the centre of the island. There were 4-  2 year olds and one large older Male, which may have been Chunk … the inflamed  right eye from an injury administered by Misery was a good identification mark.

Two Northern sea lions were observed in the water . I thought it was notable that there were very few harbour seals which usually have pups at this time of year, and none on the southern islets where they usually haul out. I will have to check over the next few days on the tower camera, as they may have been out foraging.

The glaucous-winged gulls are well into nesting season, with several nests containing three eggs. The image from the window of the science centre shows the distribution of pairs. Another picture above shows a nest precariously close to the elephant seal  haulout spot.

There was an abundance of pigeon guillemots on all corners of the island where they have their nesting burrows. They should be visible on camera 5 now out near the edge of the cliff to the west.  They have certainly been a success story in increasing numbers in the past few years. There must be well over 60 pairs nesting in the hidden burrows under the rocks. Ironically good habitat has been produced in several areas because of  human activity in the past by the blasting  of rock for the helipad construction by the Coastguard, and other construction on the islands done in the 1900s before it was an ecological reserve. This is a rare example of habitat enhancement that humans can claim, as usually it is the other way around.

On the return to the docks we were impressed with the clumps of Thrift in full bloom. Chris mentioned that the Black Oystercatchers had been in the area on the rock right off the sidewalk by the docks and we soon spotted the nest. This is the same area they have used for many years. The videos of the hatching oystercatchers in this link  are from the same area.

In addition to the vast monocultures of pineapple weed as shown above, this is the second year we have noted large patches of Fiddleneck, Amsinckia spectabilis in the same compacted and richly fertilized areas where the grass was killed out by the sealions and intense Canada Goose grazing.

Census Jan 8

Black Oystercatchers (over 100–a record for RR)  and gulls with westerly swells.

Green Winged Teals

The SGBs (Small Grey Birds). Not only do they all look very similar but they hide their beaks! There was a mix of Black Turnstone, Surfbirds and Rock Sandpipers in the NE bay.

On January 7 an 8th there was a W wind 30-35 knots.  The Green Winged Teals returned to the island with slightly higher numbers than last time, they spent their time in the pools on the NE side and picking through the mud with their beaks.  I  have not seen any Pelicans in about a week and there have not been any Canada Geese here for about two weeks.  Karen Benzel from International Bird Rescue contacted us recently to report that Pelican R36 that was seen here in November has been taken in for rehabilitation at Wild Arc in Metchosin.

Animal Notes and Census

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.

A visitor from warmer climes….

Northern vacation to Race Rocks….

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…

The fog is lifting!

 

View looking to North Race

Today was my first view of the mainland for the past couple of days excluding a few glimpses here and there.The past week has brought constant fog and winds of 20-40 knots which means boat traffic has been minimal. (At least as far as I can see!)

 

Newborn Black Oystercatcher

Today though, the sun has come out and with that yet another newborn. The Black Oystercatchers  (Haematopus bachmani) are hatching. These birds live mainly in the intertidal zone. Where the chick is shown in the photo below is where it just hatched and effectively camouflages itself. Quite a difference from its nest to that of the gulls’.

On another note, the elephant seals are spending more time wading in the water and are holding their breath for longer periods. I was startled the other day when I looked near the jetty to see one limp underwater only to realize it was snoozing and would come up for air every few minutes.

Glaucous-winged gull juvenile

 

And finally, an updated picture of one of the three infant gulls in past posts. It has become more difficult to get pictures of all three because they are more mobile now.

 

 

 

 

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.

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

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.

 

Bull Misery has returned

The big boss is back. Misery (Mystery as I like to call him) has returned to the island and has been snoozing and rolling his generous bulk around the grassy areas. He appears to have gained 100 kgs or more in his time away. Wherever they are going after their onshore fasting, and it can’t be too far, the seals appear to have no problem finding abundant food resources. Fortunate for them that their prey is at a depth most predators can’t reach, nor is that prey (squids, skates, rays and some crustaceans) commercially hunted. Elephant seals appear to love grass, which is unusual as most of the places they live don’t have any vegetation. But their pleasure is apparent to anyone who watches them. Yesterday there were 10 individuals here, a new record.

The younger bull Chunk (named for the hideous propeller scars on his back) stays out of the way but Misery seems less aggressive without any potentially fertile females around. A new juvenile with the tag 6355 showed up today.

 

 

 

 

 

 

 

It is hard to tell if the oystercatchers have laid their eggs yet because they are so secretive about their nests, and use very vocal and visual threat displays to distract would be predators and naturalists. Normally 2 to 3 eggs are laid in this nest, these are very hard and can even survive being submerged by a high tide or very high water levels. Incubation takes around 26–28 days. The chicks are capable of leaving the nest after one day. I once witness an acquaintance of mine accidentally step on an oystercatcher nest and crush an egg. He was devastated but not as much as the bird. She clearly knew we were responsible and proceeded to fly after us carrying shards of egg in her beak and screaming what I took to be obscenities at us. I don’t blame her at all. Remarkably she repeatedly flew ahead of us with the broken egg, landed on the beach and vocalized, until our guilt forced us to flee the island. That bird recognized cause and effect!

Aneri and Sahar are staying here for a few days and they have been great company. They are so much more consciously evolved than my generation was at that age and they give me hope that many of the antiquated paradigms of our culture will go extinct and we can progress to 21st century thinking to solve 21st century problems. I shall miss them when they leave tomorrow. They have helped me prop up some of the solar panels, washed windows, swept walks, and made some tasty brownies!

End of May

Hold the presses! I just got back from the top of the tower where I was washing the windows. My eyes were drawn to a huge lump on Middle Rocks. With the binoculars I could see what appears to be 3 bull elephant seals, a few cows and a juvenile. That makes at least 14 elephant seals in the reserve! I wonder if it is Misery?

It is hard to tell that June begins tomorrow, due to the fog and damp. But there are certainly signs of summer beginning to show up in spite of the weather. The first Glaucous-winged Gull eggs are being laid, the Oystercatchers are getting more secretive

 

But the really BIG news is that a new-to-me bull elephant seals arrived yesterday. He isn’t as big as Misery but he is bigger than Zeke. I would guess he is a few years away from becoming a Beachmaster. He caused quite a commotion rampaging around and roughing up a few females before he found a nice spot to sleep for the next few days. I have named him Chunk, for both his size and the large scars down his back, which appear to be caused by a boat propellor a few years ago. (Ed note: These were actually caused by a fight with Misery last year. ) The scars look fairly well healed but some pretty big chunks were carved out by the prop.
