kayak disturbance, tagged e-seals, pup, etc

Posted on by

Wind has varied between W and NE less than 20 NMPH over the past few days.  We have had some patches of fog during the week and partly clear skies today and yesterday.

On the 15th a group of 20 kayakers passed through the reserve on the East side heading West.  They passed on both sides of East rock and caused one of the largest sea lion disturbances I have seen here, several hundred sealions scrambled into the water.  I was able to talk to one of the kayakers as they passed by the south side and told him that they are not allowed to cause this kind of disturbance to marine mammals at race rocks. Though I love kayaking and prefer kayaks to motorized vessels, kayakers need to realize that because they are so nice and silent they can also easily surprise wildlife.  Once startled sealions stampede and can easily trample younger sealions or injure themselves rushing over the jagged rocks.

1 dive boat in the reserve today, 1 eco tour in the afternoon, 1 sports fishing boat in the morning which traveled too close to sealions on the East rocks. I called Pedder Bay Marina and gave them the ID number and a description and asked them to talk to the operator about regulations at Race Rocks (thanks Pedder Bay Marina!).

The elephant seal pup seems to be in good shape and is drinking milk regularly. Chunk seems fairly well behaved, a few times a day he we will arise from his slumber and chase after Bertha. Sometimes it seems he is trying to separate her from the pup and restrain her. I have seen him with his mouth around the pup’s head as well as with the pup partly underneath him though on all occasions I have observed he has clearly not harmed the pup when he easily could have. Chunk went off the island last night, I assume to middle rock and was back in the morning. There are two elephant seals on middle rock, both fairly large, one possibly a young male. I have been hearing what sounds like a male’s call coming from middle rock today. There were also two smaller scruffy, moulting female elephant seals in the shoreline of the main island today one tagged green 7502 the other tagged pink N93_ the last number is not visible. That brings the current e-seal population to 7.

Where do the gulls go at night?

Glaucous-winged Gull

Glaucous-winged Gull

The Glaucous-winged Gulls (Larus Glauscens) is an almost ever-present fixture of Great Race Islet. This time of year from dawn to dark they can be seen occupying their potential nesting locations, building those nests, and settling territorial disputes with their neighbours. But many nights, when I head out to turn the generator off, I discover a silent and empty island; 300 gulls have simply disappeared, gone to some mysterious location I can only guess at. Do they prefer to sleep on the water? Do they feed on certain foods at night? What’s going on out there at night!

Sunset Soaring

Sunset Soaring

Regardless, I can tell you that Glaucous-winged Gulls are an extraordinary bird, at home on the lightest of breezes or duelling with the 50 knots gusts of an afternoon’s Westerly gale. Only in their ubiquitousness do we loose sight of their beauty and efficiency. They are masters of their realm.

In other news, yesterday there were 10 elephant seals in the yard and on the boatramp! This is a new record for Great Race. There are 4 young males, Bertha the mature female and 5 smaller females. A good-sized male is out on Middle Rock but it doesn’t look big enough to be Misery.

Juvenile Bald Eagle

Many eagles are in the reserve, most juveniles. I watched one hunt a gull this morning and was surprised how the eagle targeted an individual gull and chased it for over a kilometer out to sea before I lost sight of them both.

MARINE LIFE: The number of sea lions continues to increase,most seem to arrive in little groups during the night.This morning counted over 50 hauled out and several small groups floating about in the kelp. There were 6 Northern sea lions swimming along the south shore when the Orcas passed by just after 20:00.The whales were headed east after feeding near Beechey Head and surfaced only twice as they went through the reserve.The geese did not visit today, guess that is it for this year,miss them in a way but there are better places for geese! The young gulls are still spending a lot of time practicing the art of landing and there were a lot of close calls with several chicks getting quite a ‘roughing-up’ from some of the more aggressive adults.Saw 4 young with pecks on their heads that drew blood and some tail feathers pulled out. The adults fly out just off shore and call to the young but they are very reluctant to follow , so it gets quite noisy at times.One California sea lion hauled out for a couple of hours on the end of the dock, he had # 62 branded on his back.
HUMAN INTERACTION: There were 33 Ecotour boats and 9 pleasure craft through today, Hyaku did a tour through in the evening.

MARINE LIFE: Happy to report, missing adult goose back with the group today, no signs of trauma and no clue to explain it’s absence.The geese arrived mid-morning and flew off again late safternoon. Saw a group of about 16 Canada Geese in the familiar V formation fly over William Head this evening so I guess it’s that time of year already! Another sign of the coming fall season is the nightly arrival of small groups of sea lions. This morning there were 8 Northern and over 30 California sea lions hauled out, mostly on the rocks just northeast of Middle rock. By noon some Californians were scattered along the ridge of North rocks and several small groups just floating about in the kelp beds. 1 California sea lion has the # 1233 branded on it’s back and saw another with yellow tags on it’s flippers but could not read the number although this evening we tried to get close enough in the boat. Many of the young gulls are finally in the water, the sea conditions were perfect today with barely a ripple, the usual afternoon westerlies did not materialize and it was one of those rare warm evenings on Race Rocks.There were quite a few gulls in the kelp just to the east of Gr. Race, some were Heerman’s gulls with their unmistakable plumage, black feet and red bills.I expect it was much cooler than sitting here on the hot rocks -the young gulls were all panting in the heat.
HUMAN INTERACTION: There were 51 ecotour boats, 13 pleasure craft, the Hyaku in from P.C. with Garry and guests about 13:30 and again about 18:30 -Ryan at the wheel- with a group tour of the M.P.A.

TEMPERATURE: Max. 18.9 C  Min. 11.3 C Reset 13.5 C
MARINE LIFE: Two mature bald eagles made several attempts to hunt Gr. Race first thing this morning and as always the gulls drove them off towards Whirl Bay everything soon settled back to the routine of feeding and sheltering the chicks.It would appear that there is a healthy supply of fish as the gulls continue to return from sea with full gullets.With any luck at all we will see some chicks fledge this year although the otter is making it’s rounds usually between 2 and 3 a.m. Most of the nests along the shore have been decimated but there are many nests farther inshore that have at least two surviving chicks.The dead seal pup has finally floated away however the female has remained in the dock area and has been joined by three other females with their pups. The geese are still here but with the vegetation so dry I wonder when they will leave for ‘greener pastures’. This afternoon two Northern Sealions hauled out on the western slope of the largest southeastern rocks to soak up some sun but were gone by 19:00.
HUMAN INTERACTION: There were 5 pleasure craft and 6 Ecotour boats in the reserve today.

MARINE LIFE: One mature Bald Eagle spent most of the day on North Rocks and made two tries to hunt over Gr. Race but was driven off each time.The gulls and oyster catchers are on the alert at all times especially the past week or so.Most gulls have nests now and soon we should see eggs hatching from the early nesters. Don’t like to disturb them as they are so nervous from the eagles and in the wind the eggs can cool very quickly.There are still 4 Northern Sealions on the southeast rocks, one was swimming in the east bay area with about 30 harbour seals which had been hauled out on the rocks until the rising tide washed them off.
HUMAN INTERACTION: Chris and Ryan in with Second Nature – 5 trips with diesel fuel. 2 pleasure craft through the reserve.

A Turkey Vulture was flying about in the strong winds,

MARINE LIFE: Early this morning one Bald Eagle flew around the Gulls nests, spending around 10 minutes looking for prey, despite the constant harassment by the Gulls. The eagle flew of to the west, and was out of site. Perhaps an hour later two Bald Eagles were spotted hunting together, they brought down a Glaucous-winged Gull and one eagle was seen carrying a Gull wing away. There was also other interesting bird action mid-morning. A Turkey Vulture was flying about in the strong winds, attempting to find food. The winds were a challenge for the vulture, with the bird struggling in the gusts. It was particularly noteworthy that the Black Oyster Catchers made a great effort to harass the vulture. This was caught on video just before the divers entered the water and can be seen at http://www.racerocks.com/racerock/archives/vidbenmovie.htm The divers reported an abundance of sperm and eggs in the nutrient rich water off the docks.
HUMAN IMPACT: No whale watching activity within the reserve today. Indeed the strongs winds, 25-35 knots, kept most vessels away. Hyaku docked twice, bringing equipment and materials for the web-cast and conduit repairs. One major disturbance was the Defence Forces Blasting on Bentinck Island which clearly frightened the Sea lions into the water, Around 10 of the 12 Sea lions disappeared within the first two blasts, approximately 10:30am, and have not yet returned. (Note: As of June 18- they have not returned- will not be back until August now. ) .The three blasts with only a few minutes spacing sent shock waves that rattled the house and were not at all pleasant.

MARINE LIFE: We were treated to a brilliant spectacle today with a pod of 5 Orcas spotted about 1-2km south of Race Rocks. The Sea lions were either unconcerned or unaware of their presence. The Divers found a large bed of sea anemones, urchins and coral while diving amongst the Bull Kelp in front of the docks. The Oystercatchers were quite agressively chasing the Crows away from their nests in what looked like an aerial dogfight.
HUMAN ACTIVITY: Again, we had fishermen within the reserve, using lures just off West Race. They moved off only after a repeated radio announcement notifying their breach of MPA regulations. The Orcas brought out a large number of eco-tourism boats, 10 moved throughout the reserve during the day. 5 recreational boats also cruised through the park, often not adhering to the no wake rule through Race Passage

MARINE LIFE: 1 mature Bald Eagle today which spent most of the time on North Rocks but did manage to circle over-head just before dark,the gulls and oyster catchers took flight as usual and drove the big bird out to sea. The eagle continued towards Bentinck island the ‘triumphant’ gulls returned to the usual noisy reception of the other birds.I can’t say things really quieted down as like the past few nights the birds are quite active. At times it sounds like we have neighbours living in the attic,noisy neighbours with heavy boots! Such small birds but they can make quite a racket especially when a bunch of them land at one time when all else is quiet! We have Oyster Catcher chicks! I saw one but know there are others. As I walked around to check out the nests the adult birds went into a frenzy of warning ‘chirps’ so I knew it wasn’t just eggs they were protecting. Did a boat tour this afternoon,counted 14 California Sealions, 6 Northern Sealions and 5 Elephant Seals hauled out on Middle Rock, also 5 California Sealions hauled out on the south slope of the SE rocks. A couple of Elephant seals are off the north shore of Gr. Race tonight, can hear them snorting so must be just off the dock.
HUMAN INTERACTION: 5 Ecotour boats, 2 pleasure craft. Station boat to Pedder Bay and back-had to get the flat tire on the truck repaired-was a great day to be on the water. Hope the wind picks up a little for the Swiftsure tomorrow -can’t believe I said that after all the complaining I’ve done over the last while about the wind! But really what is a sailing race without wind!
