oyster catcher: 11 adults, 3 chicks
pigeon guillemot: 24
great blue heron: 1
surfbird: 5
black turnstone: 1
harlequin duck: 1

Wildlife notes:

To the census I have to add 12 small flashes of white, travelling in a tight group – did some impressive high speed acrobatics on the north shore.  The pigeon guillemots are under represented. They have been travelling in and out all day with few remaining on the island at any one time. Their nesting locations are easier to spot now. The birds land near the nesting area with their prize and stall for a while, seeming to look about cautiously before they approach their nests, but perhaps they are just showing off their catch. The California sealion has a wound (one large and central, one smaller near the tip) on his left flipper and has dipped in and out of water many times today.  The black oyster catcher chicks on the bolder beach near the house, first photographed June 12, are now about half the size of their parents. A new black oyster catcher chick hatched today on the western shore, in the open without any sort of nest. Not many new gull chicks today. The elephant seals continue to tumble and grumble, then separate and ignore each other.

New Man

I left Race Rocks for a dental appointment and returned to find a new man. The male elephant seal looks fantastic and has a smooth, shinny silver sheen to him.  He is still bothering the female elephant seal but at least now she is permitted a piece of subprime real estate, while he lounges in grassy hollow and near the house.

Wildlife notes:

Only a few more gull chicks have hatched with the majority of the gull parents still incubating their eggs.  A different banded gull than that noted on June 20th was found on the southwestern shore. Both gulls were reported to researchers at the Salish Sea Gull Project… read more.  Two surfbirds and one black turnstone visited the northeast rocky beach and one newly fledged California gull on the rocks east of the jetty.

Weather:

ESE 4-9 knots most of the day, veering to W 17 by early evening.

Unwelcomed visitor

The male elephant seal was disturbed this morning to find a new female in his favourite grassy spot.  He chased her around, bit her, climbed on her and sent her down the boat ramp into the water. This all took a while as both had to stop frequently to rest. I had a chance to watch him in the water – effortless!

Wildlife notes:

Still only a few nests have chicks hatching. The chicks that hatched on June 28 are growing rapidly.  They wander less than a foot away from their old nest and sit motionless and cuddled together when an approaching eagle sends their parents to the air.

Bare belly

More house deep cleaning today – getting behind the furniture and doing baseboards. A quiet day for the elephant seal in the grass. He didn’t move than a few meters, mostly just rolling over. His belly is now mostly bare but his back is still covered.

Wildlife notes:

1 surfbird, 2 Caspian turns, 2 harlequin ducks and several eagles were sighted. Did not see any others gulls near the house with newly hatched chicks.

Surfbird

Two days old. Hungry for lunch.

Facility work:

  • cleaned solar panels
  • thistles – new record, a 13″ root
  • house cleaning

Vessels:

18 Ecotourism boats, 5 private, 3 kayak

Weather:

Westerlies 9 knots and partly cloudy in the morning. Westerlies 15, overcast and scattered showers in the afternoon.

Gull chicks are hatching

Wildlife notes:

The first gull chicks are hatching! I may not be so happy about this in the coming days as the gulls become less tolerant of my presence (I got nailed again today). Just as some checks are hatching, a few gulls are still building nests. This week while lowering the flag before a gale, I noticed a new nest with one egg on the west side of the flag pole base.  Now two sides of the pole could be inaccessible should they protest.

The elephant seal has become interested in the crawl space under the Keeper’s house. He’s pushed against the crawl space door and succeeded in dislodging it. I also caught him glancing in the basement window. I hope he never sees his reflection.

Facility work:

We had trades people at the site today.  The woodstove and chimney were cleaned and the fire bricks replaced. This inspired me to do some cleaning inside the Keeper’s house that didn’t require much water like windows and other shiny things.

  • cleaned solar panels
  • cleaned Keeper’s house windows
  • cleaned inside Keeper’s house
  • thistles

Winds variable, seas calm, high of 17 degrees.

Moving house

Windy Day

It was a windy day – blew the door off the Derrick Shed and the hair off the elephant seal’s head. The electric fence suffered from the winds over the past few days and needed replacement strands in two sections.

Wildlife notes:

The pigeon guillemots were around in the morning and mostly left again by 7pm. I found what I assume to be a pigeon guillemot nest in the rocks at the west end of the helipad.  Judging by the egg orientation, the little bone and other items which get moved around, it seems to be an active nest. Two least sandpipers were spotted on the northeast shore.

Facility work:

  • cleaned solar panels
  • replaced 2 sections of electric fence
  • thistles – new record, an 11″ root.
  • topped up battery fluid

June 26th Census

Mammals

sea otter: 1
California sea lion: 4 (2 South Islands, 2 Great Race Rock)
elephant seal: 1 (male)
harbour seal: 139 (60 South Islands, 9 South Seal rocks, 29 Middle,  24 Turbine, 17 North Island)

Birds

bald eagle: 4
cormorant: 14
gulls: 415

Facility work:

The overcast conditions necessitated running the generator for 4.5 hours.

  • cleaned solar panels
  • thistles
  • kindling

Vessels:

9 Ecotourism boats, 1 private

Weather:

Windy day. Low cloud, distant fogbank, winds W 29 in the morning with gusts to 36 by mid-morning. Cloudy throughout the day, scattered showers. Winds WNW 19 in the early evening.

DND:

Several blasts today.  No obvious signs of distress.

White stuff

The male elephant seal is an unsightly mess. His hair is falling out, he is covered in flies, foaming from the nose and has a poo smear running the length of his belly from dragging himself through his excrement. He probably can’t see well, is slow moving, uncoordinated, and can’t grab a hovering gull <1 foot away from his open mouth.

To be fair, we are seeing him at his worst. In the sea, this creatures is an extremely manoeuvrable master diver and hunter! He can easily hold his breath for 20 minutes and dive to 800 m (maximums of up to 100 min long and 2 km deep have been recorded). His eyes have adaptations for low light, his vibrissae (whiskers) can detect vibrations, he can reduce blood flow to his extremities, has a large blood volume with a high red cell count and can store extra blood in his abdomen and spleen to release slowly during his dive. And that white stuff oozing from his nostril?  It is a pulmonary surfactant that reduces the surface tension of the fluid in the lungs but it also acts an anti-adhesive. When he dives to great depths the pressure is so high his lungs collapse and this surfactant stops the lung tissue from sticking together allowing the lungs to later expand again.

Wildlife notes:

The gulls were very testy today. I got nailed with a wet, warm, smelly bomb right in the head and across my glasses, and it was first time I had raise my broom to intercept a diving gull. The first chicks should hatching any day now.

Facility work:

  • cleaned solar panels
  • thistles
  • survey and brush the electric fence line
  • vacuum and clean main basement room

Vessels:

5 Ecotourism boats, 4 private

Weather:

Sunny day, calm seas, winds light and variable 4-7 knots.

DND activity:

Three blasts heard and seen from Bentinck Island. No obvious signs of distress.

 

Digital Dexterity

An elephant seal moving on land is anything but graceful. Their rear flippers are not useful for locomotion on land. They use their front flippers to propel themselves forward on their bellies. Their forelimbs or front flippers however, are capable of precise, controlled movements, perfect for getting that itchy spot or wiping away the flies.

Wildlife notes:

Single eagles visited today. The gulls would really have an easier time if they just worked together in both scaring off the eagles and dealing with the steamroller elephant seal. While all the gulls are flying about and screaming bloody murder, only one brave gull chased the eagle on two trips around the Great Race and the surrounding islands.  The male elephant seal has lost more hair on his nose, around his eyes and the hair on his body is coming off in patches.
