Moulting Time

There are about 8-10 young and mostly moulting elephant seals in the reserve at this time. Between four and six have been lounging on the pier creating obstacles for the group of 10  students that spent the weekend here. The grumpy infected girl at the end of the dock made all of us clamber around the outside of the rail to get to and from the boat. Today I thought she looked a bit better. There appears to be an object imbedded in her lower palate; perhaps a barb or spine from a fish she was hunting. I hope it works it’s way out in time. Presumably elephant seals are pretty durable creatures… we will keep a close eye on her recuperation.

The students did a great job of weeding the scotch thistles from around the tower.

There are plenty of Pigeon Guillemots and Black Oystercatcher pairs on the island, with a few Harlequin ducks and Rhinoceros Auklets just offshore. The Harbour Seals should start giving birth soon. There is a large pregnant female on the foreshore near the engine room.

3 rental boats entered the reserve and broke all the rules for respectable human decorum here. I called the marina and they quickly responded by phoning the renters to warn them of their infractions. I was happy to see them promptly exit the reserve and head off towards the military ballistics range.

Project Week-part 3 (final)

Yesterday was the last day of project week, in the morning I brought students back to campus in two trips on the whaler.  It has been great group to have out here for the past week, they have helped out with several projects and tasks, endured some stormy weather, survived without a shower, cooked their own food (and shared a few good meals with me), and experienced the isolation and richness of the Race Rocks Ecological Reserve.  During their stay they were very conscious of the time and resources required for importing fuel and generating energy and fresh water and did a great job minimizing consumption and waste.

In the final days of the week students helped out with transferring diesel to the furnace tanks and cleaning cupboards in the science centre kitchen.  Throughout the week the group maintained a daily count of animals in the reserve, the count is included below.

Tagged juvenile E-Seal

There are six E-seals on the island today. The big bull Misery, Bertha, a seemingly very pregnant large female with a distinct scar on her belly, and four youngsters resting uncomfortably on the rubble beach near the engine room.

The scruffy pup closest in the picture has a green hind flipper tag. The number appears to be #6355. I will look for info about from where and whence it cometh

Over 60 black oystercatchers (Haematopus bachmani) are on the rocks on the south perimeter of the big island.Never have I seen a flock like this! Usually a person is lucky to see 10 together at a time. Along with the Haemas are about 40 Blackheaded Turnstones (Arenaria melanocephala).

2 divers in the water at West Rock. An Italian student and her friend are out for 3 days, as is another guest who is a professional photographer. I will try and get some good pics of the seals from her…

New year for the Humans, just another day for the seals…

An enjoyable end to 2011 starting with the gale on Friday. Winds hit 50knots. I have noticed that cormorants are the last birds flying when the wind picks up. Today the islands of the reserve hold about 30 Stellars Sea Lions, 30 Harbour Seals, 2 elephants seals, 100 cormorants, 200 herring gulls, 15 oystercatchers, 20 turnstones, 10 Canada geese, a couple of sandpipers and sparrows, and one Homo sapiens sapiens. How is it that they can find food where they live but I am required to import it from the 4 corners of theglobe?

I am renaming the bull Elephant Seal Mistery rather than Misery as he was previously nicknamed. Misery doesn’t do this magnificent animal justice, plus I like him a lot; he brings me joy!

Pearson College Students at Race Rocks

Jake and Aaron installing tilt kit on a second block of solar PV panels

On Friday afternoon Chris brought a group of 5 students and Jake to stay on the island for the weekend.   The group was a big help with several projects including installing a second solar PV tilt kit on the roof of the Engine Room, helping build a rainwater capture system, relocating construction materials, and transferring diesel for heating.

On Saturday Danie made marine life observations on the South side of the island, she counted 5 sealions, 40 Cormorants, 10 gulls, and 7 Black Oyster catchers. Also on Saturday Julie did a Marine Sciences research experiment on the relationship between ocean current strength and depth.  While conducting the experiment we had some trouble with the outboard engine fuel line on the Whaler so Chris came out in Second Nature to get us going again.

Today around 11:00 hrs Chris came back out to the island to take them all back to campus. It has been another great weekend with students at Race Rocks, big thanks for all the help and good times.  Also. thanks to Jake for taking the lead on the tilt kit and to Chris for providing support and transportation on the weekend.

Census, birds and mammals

Sea lion populations have stabilized in terms of numbers. With just ~250 California’s and ~150 Steller’s. Ever since the earthquake on 09/09/11 (which was not felt by me here), the sea lions have moved up from “the arena” and East bay on Great Race to surround three sides of the Keeper’s residence. They have blocked 2 of 3 entrances! They can be shooed away, but return during the night. The cool winds and overcast days permit them to sleep comfortably during the day only to be particularly raucous during the night. The transition between Glaucous winged gulls and their winter replacements the Thayer’s gulls has begun. Some Heermann’s gulls are present now as well. It appears at least one oystercatcher clutch was successful as an adult pair and their two fledged chicks are still present on Great Race.
