Census and a Beautiful Day

Posted on by

Weather: 

  • Visibility 0-10 NM (some intermittent morning/evening fog)
  • Sky clear
  • wind 25-30 knots W
  • Sea state: rippled, whitecaps
  • A steep decline in humidity today helped dry out the island after a bit of rainfall

Neat Fact: The body temperature of seals is very similar to our own! Endothermic like us, they maintain an internal temperature of 36.5-37.5 degrees Celsius.

Marine Traffic/Visitors: 

  • Greg visited today to top up island supplies before the college vessel goes for regular maintenance
  • Not many boats today- around 5 eco-tourism vessels.

Ecological Observations:

  • Elephant seal V173 was not here today. We wonder if she was just stopping for a rest or if she will be back soon.
  • There have been very large groups gulls and also black turnstones migrating through, intermingled with a few surfbirds. There were so many today that we took a photo from the lighthouse in order to count them!
  • The pigeon guillemots seem to be nesting in full force. We have spotted many carrying fish into crevices on the west side of the island near camera five and also the rock walls on the east side.
  • The seagull takeover has seemingly started to ease and moving around the island is becoming easier day by day. The chicks are beginning to be able to escape the attacks of the rival adult gulls by flapping their wings and flying/hopping away.
  • On a slightly…mushier note (stop reading if you get queasy!): Yesterday we removed the gull that was eviscerated on our back porch. We let it sit for a few days to see if an otter would come back for it or if the gulls might take a nibble (neither occurred). We were surprised by the amount of maggots that had grown in only a couple of days, presumably due to the warm and humid weather recently.
  • The sea lion population is increasing every day and they are started to climb onto the main rock. It’s almost time to put up the electric fence or we will have unwelcome house guests!
  • The geese have suddenly left this week (all but 4). Interestingly, earlier in the week we saw a flock of 17.

Census: 

  • 4 Canada geese
  • 985 Seagulls (does not include chicks)
  • 84 Harbour seals
  • 1 Male elephant seal
  • 25 Stellar sea lions
  • 19 California sea lions
  • 88 Pigeon guillemots
  • 2 Bald eagles
  • 1 Humpback whale (in the straight)
  • 1 Brandt’s cormorant
  • 12 Black oystercatchers
  • 143 Black Turnstones
  • 1 Sandpiper ((?) will update with confirmed id!)

 

 

 

Glaucous-winged gulls nest

Posted on by

Weather: 

  • Sky partly cloudy (intermittent fog)
  • Visibility 15+ NM (less than 400 m this morning)
  • Wind 15-20 knots W
  • Sea state: calm, rippled

Marine Traffic: A few eco-tourism vessels over the past few days. One approached extremely close to the sea lions today.

Ecological: 

  • The five goslings seem to have been eaten by another animal, perhaps eagles. We have not been able to spot them in two days, since we had a very stormy night. We found one gosling deceased near our back steps following the overnight storm. It appeared that it had become separated and could not survive the elements alone.

Otter, Caspian Terns, Goslings (!) & Sunday Census

Posted on by

Weather:

  • Sky clear, a few clouds
  • Visibility 15+ NM
  • Wind: 30-35 knots W
  • Sea state: fast moving, white caps breaking at .5 m

Visitors:

  • Greg visited with a water delivery on Friday
  • One eco-tourism boat in the reserve yesterday evening.
  • One vessel fishing within the reserve on Friday afternoon. They approached the sea lions around the jetty very closely and their dog on board barked loudly at the animals. They approached the animals within a stones throw and hovered for roughly 20 minutes. The animals appeared distressed and fought with each other as they tried to move away from the boat (it was too close for them to enter the water).

Ecological: 

  • On Thursday evening a river otter came onto land near the jetty. We wonder if it was trying to steal seagull eggs.
  • On Friday afternoon two caspian terns flew overhead. The seagulls were not happy to see them and chased them out of the reserve.
  • Related to the post linked above, we spotted an oyster catcher nest on the west side of the island. We think it could be the same one that Mike spotted in 2012!
  • There are five goslings total, one family with two and one with three. The family of three has been joined intermittently by the other two. The two chicks seem confused as to which geese are their parents, and they’ve even managed to sneak under a wing with the rest for shelter. The parents continuously try to separate them from their own three chicks and the parents of the two follow closely behind.
  • We have observed the geese moving around the island trying to find fresh water. When it rains it is easier for them to come near the structures and drink the water from our roofs. When it is dry, they are limited to what they are able to find in the pools high on the rocks, usually full of algae and very dirty. We have been learning about their adaptations to drink salt water here.
  • The two oyster catcher chicks that we spotted earlier in the week have maintained their elusive nature. We haven’t been able to spot them again, as they are hidden by their parents among rocks where the seagulls are not able to attack.
  • This week has brought an influx of stellar sea lions, particularly smaller youngsters.

Census:

  • 2 Elephant seals (1 male, 1 female)
  • 46 Harbour seals
  • 326 Seagulls
  • 10 Stellar sea lions
  • 17 California sea lions
  • 10 Black Oystercatchers(adult)
  • 2 Oystercatcher chicks
  • 16 Canada Geese (adult)
  • 5 Goslings
  • 2 Pigeon Guillemots

A Foggy Day

Posted on by

Weather:

  • Wind: 5-15 knots NE
  • Sky: Foggy, some showers
  • Water: Rippled
  • Visibility: Up to one mile

Visitors/Boats:

  • We haven’t seen very many boats today as it has been very foggy. We spotted three whale watching vessels, and one unmarked zodiac.
  • Yesterday was a busy day for whale watching, with boats heading in many directions through the main passage. There has been a young elephant seal resting on the jetty for the past two days, and it appears very agitated when the boats come close (within 25 m).

Ecological: 

  • We have noticed that there are a handful of sandpipers on the island this week
  • There is a small elephant seal with a few minor flesh wounds on its abdomen resting on the jetty. It appears to be part way through the moulting process.
  • We spotted two deceased oyster catcher chicks on the paths this week. They were very small, so its possible that they were unhatched. They didn’t appear to be injured. The other chicks are thriving and growing incredibly quickly.
  • Another male stellar sea lion hauled out onto middle rock a couple of days ago.

Maintenance:

  • On Monday a plumber came to fix a leaky faucet part in the main residence.

Visitors of All Kinds

Weather: 

  • Wind 5-15 knots SW
  • Sky: Mostly grey, cloudy. Some rain and fog. Periods of partial clearing.
  • Water: Rippled, fairly calm.
  • Visibility: 10-13 miles

Boats/Visitors: 

  • Guy came to pick up our weekend visitors who headed home this afternoon. It was nice to have some company out here on the rock!
  • There were only a handful of whale watching boats in the reserve today since it was quite cloudy and rainy. We were surprised to discover a vessel hovering within 50 meters of a whale within the reserve this evening.

Ecological: 

  • While taking a water temperature reading we accidentally spotted a humpback whale hovering in the main channel! It stayed for about 30 minutes, surfacing approximately every 5 minutes in the same spot, facing towards the current.
  • The seagull chicks have continued to hatch and there are too many to count. They blend in with the yellowing grasses extremely well and have grown to be twice their original size in only a week. We noticed that one chick near the fuel shed hatched but did not survive, while its two nest mates appear to be healthy.
  • There has been one male stellar sea lion on middle rock for the past few days, and appears to not be moving much at all.
  • The goslings are nearly full grown now, and have been swimming

  • 230 Harbour seals
  • 350 adult seagulls and many, many chicks
  • 4 moulting male elephant seals
  • 1 male stellar sea lion
  • A handful of pigeon guillemots
  • 8 adult oyster catchers, at least 7 chicks spotted
  • 1 humpback whale
