A Big Storm + Lots of Birds! (census)

Posted on by

Weather Today: 

  • Visibility 14 NM
  • Sky partially overcast
  • 30-55 Knots SW
  • Sea state: swells up to 2m, otherwise 3-4+ ft chop

Visitors/Traffic: Nothing other than a few fishing and shipping vessels in the strait.

Ecological Notes: 

  • We found another apparently healthy gull dead today; this is the fourth one since the beginning of the month. We now have two preserved for necropsy, which we hope to transport to land soon to be investigated. They have all displayed the same odd symptoms: weakness in the wings progressing to unable to move, wings dropping to the sides, and unable to make any sound.
  • This week there have been an incredible number of cormorants in the reserve! An underrated bird, they are very fun to watch as they waddle, preen, and fish.
  • We’ve been noticing some fungi popping up around the island now that we are into the rainy season! Photos below. These are in addition to the shaggy mane mushrooms we found last spring fruiting beside the composters.
  • Last week we spotted another “neck wrap”: a california sea lion with some kind of pollution material embedded into his neck. Unfortunately it seems that he is no longer present in the reserve, making a rescue improbable.

Census:

  • 4 black oystercatchers
  • 1 dunlin
  • 1 ruddy turnstone
  • 9 black turnstones
  • 3 surfbirds
  • 500 Thayer’s gulls
  • 17 Canada geese
  • 1550 Cormorants (wow!)
  • 2 bald eagles
  • 100 stellar sea lions
  • 502 California sea lions
  • 2 harbour seals

Seagull Stones and Census

Posted on by

Weather Today: 

  • Visibility 10 NM
  • Sky overcast
  • Wind 10-15 knots SW
  • Calm seas earlier in the day, rougher later on – swells 1-2m high

Visitors and traffic: 

  • Some old equipment is being moved to land, so there have been a couple of runs back and forth to the college.
  • The usual 5 or so whale watching vessels daily, very few pleasure craft as the weather gets worse.

Ecological Notes: 

  • We have been seeing whales every day, both humpbacks and orcas!
  • We thought the sea lions were beginning to move along for good but they came back – it has been interesting to observe how suddenly it can go from a couple hundred hauled out to perhaps only 50. They must leave in the night as we have yet to notice it as it happens.
  • Unfortunately we have another sea lion hanging around that has plastic around its neck.
  • While doing some work on the jetty today I (Kai) noticed an interesting pile of small stones piled up in a corner of the railing. We often see seagulls, especially the ones that look younger, playing with rocks of the same size. They are usually together in a group of 2-4 and they’ll take turns moving a rock around, holding it in their beak, and trying to take it away from each other. It seems plausible that the seagulls placed the rocks there, we haven’t seen other animals interacting with each other and objects this way.

Some photos from the last couple of days:

Weather Today: 

  • Visibility 1-5 NM
  • Sky overcast, moderate fog cover
  • Wind 10-25 knots W
  • Waves up to 0.5m

Visitors and traffic: 

  • On Sunday we had a burst of whale watching activity, some around North Rock but primarily south of the reserve near the Rosedale Reef marker.
  • We have had some supplies (water, etc.) delivered over the last couple of days.

Ecological/Weather Notes: 

  • We woke up in a fog bank on Monday and the fog has stuck around, although with periods of clarity. It sounds like Vancouver Island is going to continue getting wet weather over this week.
  • As mentioned above, on Monday there were 2 minke whales (?) in the general area of North Rock and some time later 2 or 3 humpbacks south of us. A good handful of of whale watching/eco tourism vessels came by to get close to the action.
  • Over the last couple of days we’ve been seeing whales daily, usually out about a kilometre in the strait but once or twice they’ve come in closer to Rosedale Rock.
  • Mara spotted some brightly coloured Harlequin sea ducks in the water just off the shore south-east of us.
  • This afternoon two large bald eagles visited. Going off of the stray seagull leg and patch of feathers near the house, they were resting after a snack.
  • As the census shows below the sea lion numbers reflect the colder weather moving in and them moving out!
  • Yesterday on the jetty, we spotted a pile of what we think are regurgitated squid quills and eyeballs.
  • Garry Fletcher kindly gave us a tip about the ‘mystery berries’ from the last log post. He suspects them to be from a Strawberry Tree (Arbutus Unedo) and was even able to share pictures of a tree and its fruit. Thank you, Garry!

Sunday Census

Posted on by

Weather Today: 

  • Sky overcast with rain earlier in the afternoon
  • Visibility 10nm
  • 25-30 knots NW
  • Swells up to 0.75 m, 1 foot chop

Visitors: Over the weekend we had roughly 5 ecotour vessels per day with a couple of pleasure craft daily. Today, a private vessel spent the late afternoon in the reserve supporting divers in the water near the jetty.

Ecological: 

  • Yesterday we were surprised by a humpback whale just off of the NE side of the rock. We spotted the whale, as well as two ecotour vessels just on the edge of the reserve, shortly after heading outside. It was huge!

Humpback Whale

  • Erica/GE103 seems to have moved along, we haven’t seen her in a few days now.
  • More sea lions seem to be hauling out, or maybe it’s just that they’re getting more comfortable! They’ve been very persistent about coming up onto the middle of the island but we’ve been able to keep them away from the burial cairns. It seems as though they are unable to read the no trespassing signs…

Visibility: 10-15 NM
Sky: overcast, then clear from mid morning onwards
Temperature: 13-15 °C
Atmospheric CO2: 412.21 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Here are the numbers from today’s census:

I was excited to see the fluffy head of the sea otter this afternoon. This morning when doing the census count from the top of the tower, I scanned the kelp but couldn’t see the otter.

This afternoon, I gave TLC to the boat house, boat and boat dolly.

There was a steady stream of about two or three eco tour or pleasure boats per hour passing through the ecological reserve.

Here are some sights from around Race Rocks today:

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)
