Orca’s at Race Rocks

Posted on by

We got some Killer Whales cruising by the lighthouse today. Some light tail slapping S of the lighthouse, overall a quick visit with no escape responses from the Sea Lions in the water. We counted 4 Orca, they looked more like Residents than Biggs’, but we haven’t ID’d which pod they are. 15 around Race Rocks before heading W out the Juan de Fuca.

 

A Diver and Dying Seagulls

Posted on by

Weather:

  • Visibility 10-20 NM, great visibility especially in the few hours before sunset
  • Sky partially overcast
  • Wind 5-15 knots W
  • Calm seas for the most part, other than strong ebbs and floods

Visitors: Some pleasure craft over the past days. There have been some supply deliveries as well as a few visitors for various reasons. Today we saw what looked to be a private vessel enter the reserve and put a diver in the water. The dive lasted less than ten minutes and when the diver was back in the boat, they left quickly.

Ecological Notes: 

  • The elephant seals are all here still – the two large and two small ones from earlier in the week. The two larger seals and one of the smaller ones have hauled themselves up high onto the island, and the other smaller seal looks to be more comfortable closer to the water. Look for them on the webcam!
  • We’ve had a few more strange seagull deaths with the same symptoms: gradual weakening (reluctance to fly and a lethargic walk), separation from the rest of the seagulls, eventually progressing to being unable to fly, and finally silent coughing/choking movements followed by death.
  • Two orcas spotted on Monday, behind north rock and heading east.
  • There’s still a heavy sea lions presence, mainly on the jetty and the surrounding rocks, and around the base of the lighthouse.
  • Mid week we had around 20 eagles in the area and were able to catch a few quick pictures of them in flight!

 

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 15+ NM
  • Sky overcast, some sunshine in the afternoon
  • Wind 0-5 knots NE
  • Sea state calm, some interesting wave patterns due to currents in the mid day

Visitors: 

  • Greg visited with a contractor yesterday along with some island supplies
  • Not too many visitors in the reserve this time of year. A steady trickle of eco-tourism boats on the less windy days, maybe 5-10.
  • Yesterday we watched the HMCS Brandon leave from its home port, Esquimalt. An impressive vessel in capabilities and design, you can learn more about it Here if you are interested!

Ecological Notes: 

  • On Tuesday we were lucky to be present for a spectacular display of orcas in the strait, roughly 2 NM to the S of Great Race Rock. The pod seemed to be hunting something, perhaps a sea lion. It was an incredible sight to observe, with the whales flying out of the water and slapping the surface with their tales.
  • We continue to see humpback whales daily, surrounding the rocks here and a bit further into the strait. Most of the time we first notice the cloud of water that forms when they surface, exhale, inhale, and dive.
  • Today we were joined by a small group of whales, smaller than humpbacks and not orcas (small dorsal fins). We are thinking that these could have been minke whales since they seemed larger than porpoises.
  • Yesterday evening we found an adult glaucous-winged gull sitting in the intertidal near our jetty. It wasn’t moving and seemed to be positioned in an uncharacteristic way, with wings splayed. We weren’t able to identify any physical injuries, although noted that it wasn’t able to make any normal seagull noises, and seemed to be attempting to regurgitate something. We were hopeful that we might be able to transport it to the nearby wild arc rescue center nearby, but unfortunately it was deceased by this morning. We are wondering if it could have swallowed a piece of human trash that may have become lodged, although we were not able to see anything when we examined it.
  • The sea lions are noisier than ever but seem to have found their places among the rocky intertidal. It is amazing to watch them fish in the early mornings, often surfacing with large salmon with a flock of seagulls close behind! I (Mara) noticed two young tagged sea lions this week that seem to be staying close to each other throughout their time here. It’s hard to say if this happens more often since it’s tough to identify individual animals among the over 1000 currently here!

Additional Notes: 

  • There has been quite a bit of blasting on the DND land over the past week to two weeks. Most of the time it is not unreasonably disruptive, but when there is a particularly large blast all of the animals on the island rush in the opposite direction.

Sun Before the Storm

Posted on by

Weather: 

  • Sky clear, blue
  • Visibility 15+ miles
  • Wind 0-15 knots W, NW
  • Sea state: calm
  • We are preparing for a large amount of rain over the next few days. Every year the “first big rain” on the west coast is quite an event!

Visitors: 

  • Today Greg visited with supplies for the island and contractors
  • Few whale watching boats now that school in Canada is back in session.

Ecological Observations: 

  • There have been quite a few more stellar sea lions this week. We will be completing our census tomorrow, weather permitting- we’ll see what the numbers show! (last week the fog delayed our census significantly)
  • The bird life has continued to change daily, with many sparrows and gulls migrating with the seasons. The pelican spotted previously stayed in the reserve for a couple of days but we did not see it today.
  • We observed a small pod of orcas passing outside of reserve yesterday evening. We have been seeing fewer humpback whales in the strait this week.
  • Elephant seal E103, or “Erica” has been enjoying the jetty with the sea lions. When we fence the island to prevent damage due to the sealions arriving we are mindful to leave space for the elephant seals to move through the island freely (the fence is high enough for them to pass underneath). Notably, Erica has chosen to remain with the sea lions nearer the jetty, as opposed to her preferred grassy areas at other times of the year. We wonder if she like the company, or if there may be a more survival based explanation for this behavior.

Other notes: 

  • As wet winter weather approaches we have been mindful to collect firewood and store it in the dry areas available to ensure dry heat throughout the winter. It is still necessary to use the diesel furnace as it distributes heat to all areas of the residence but the dry heat from the woodstove just can’t be beat! This wood is collected from the ocean as winds in the winter season push logs fallen from barges into the jetty waters.

 

An Exciting Few Days- Orcas!

Posted on by

Weather today: 

  • Blue skies with a few small clouds blowing by
  • Visibility 10-15 NM
  • Wind 10-25 knots SW
  • Sea state 0.5 m chop

Visitors: 

  • No visitors today, but over the last few days we have have been joined by Greg and a technician to service equipment and deliver supplies to the island. Environment Canada personnel came to update weather equipment on the lighthouse with new sensors and other hardware!
  • A handful (5-10) eco-tourism vessels have been though the reserve daily as well as the same for pleasure crafts.

Ecological Observations: 

  • Over the last few days it has been very interesting to note the development of the seagulls chicks during our two week absence. The majority of them can now fly, although many appear to spend time in their respective nesting areas. While the young ones spend time on the water and practice bobbing their heads under, they still beg for food from their parent(s).
  • There have been 2-5 explosions daily, except for today, at the Esquimalt Canadian Forces Base. They seem to be varying in intensity – sometimes only a sharp ‘thump’, while other times the whole house shakes! The animals in the reserve certainly notice the latter. We sometimes see the majority of the landed birds and hauled out pinnipeds in the area flee to the water or air on these occasions.
  • On Tuesday we observed a larger pod (5-6) of orca whales move through the reserve and the surrounding waters. We first spotted them to the inside of north rock and over roughly 20-30 minutes they moved around great rock to opposite side. It looked as though they may have been hunting (moving towards shore in a line formation) but we were not able to see their prey.

August 20 – Two Pods of Transient Orcas!

Posted on by

Wind: W at the beginning and end of day, NE mid morning to early afternoon, 4-18 knots
Sea State: calm
Visibility: 0-10 NM
Sky: fog in morning, clear in the middle of the day, overcast in afternoon, rain in evening
Temperature: 12-17 °C
Atmospheric CO2: 412.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There was a lot marine mammal activity today. At 11:00, two pods of Bigg’s transient killer whales were in the ecological reserve. One pod appeared to have about six whales. The other pod appeared to have three. Both pods spent a lot of time around the South Islands. A nearby whale watching boat captain mentioned on the VHF radio that the orcas were two families most likely having some social time. They were probably having a good meal too. I didn’t see any hunting happening on the surface. Transients eat marine mammals like seals. I did see a lot of harbour seals not taking any chances, huddled together on nearby rocks and around the east bay beach, looking towards the areas where the orcas were swimming. The transients stayed around until at least 3:30.

See the photos below for views of the orcas and other sights from today:

Foggy Days and Sea Lions

Posted on by

Weather:

  • Sky overcast, heavy to medium fog
  • Visibility 1 NM (less than 1 during heavy fog)
  • Wind 5-15 knots W
  • Sea state: rippled to small waves less than 0.2m

Marine Traffic/Visitors:

  • A small handful of eco-tourism boats came thought the fog today.
  • Over the weekend, Sunday especially, there were many small pleasure crafts and a few eco-tourism vessels

Ecological Observations: 

  • A pod of four orcas was in the reserve on August 6th! They stayed in the area for about 10-15 minutes before heading towards Pedder Bay!
  • The sea lions are returning. Over the last few days there has been at least a dozen hauled out on the north side of the island near the crane, with more on the outcropping rocks.
  • The seagull chicks seem to be growing faster every day – we’ve spotted a few that are beginning to fly short distances.
  • When we do our water sample from the jetty we see pigeon guillemots perching up on the nearby rock, always in pairs, and sometimes with fish. They are very tricky about waiting until nothing is watching to take food back to the nest!
  • The fog and the nesting birds keep us inside most days without a good view of animals. More pictures and a census to come as soon as we can see!

Census:

  • 40 California sea lions
  • 51 Stellar sea lions
  • 111 Harbour seals
  • 1 Elephant seal (male moulting)
  • 552 Glaucous-winged gulls (nesting, some chicks that are big enough to see included)
  • 388 California gulls
  • 12 Oystercatchers
  • 112 Black turnstones
  • 2 Ruddy turnstones
  • 1 Surfbird
  • Pigeon guillemots were not visible at the time of this census (very windy), but the numbers have been consistent from last week as they continue to care for their young.

A New Arrival

Posted on by

Today’s Weather Conditions: 

  • Sky overcast
  • Visibility 15+ NM
  • Wind 15-20 knots W
  • Sea state: calm, fast moving currents today (almost 5 knots)
  • Daily fog in the mornings and often late afternoon as well

Marine Traffic/Island Visitors:

  • No island visitors aside from Greg on Thursday with supplies
  • Quite a few whale watching boats today and yesterday (20+)
  • Not many pleasure crafts passing through the reserve, but many outside of pedder bay (especially yesterday)
  • We saw 3 whale watching boats just outside the reserve circle a small group of orcas and follow them under power into the strong currents earlier this afternoon.

Ecological Observations: 

  • Today we were joined again by elephant seal V173. She was also here in December and again in the late spring when we first arrived. Her left eye is a bit oozy and red, but it seems like it is still functioning properly and she is otherwise looking great! She must have eaten a lot of fish out there- she’s much bigger than the last time we saw her only a few months ago.
  • The seagull chicks have been wandering farther away from the safety of their nesting areas, and we have been seeing quite a few more deceased chicks on the ground all around the island. They are being killed by rival gulls protecting their territory and young. There are a few chicks with injuries from these attacks, such as broken legs or wings.
  • We found an eviscerated gull chick on our back step on Friday afternoon. It looks quite a bit like a chicken does when a mink kills them (head missing), so we wonder if this is the work of a river otter.
  • As mentioned above we observed a few orcas just outside of the reserve earlier today. We have also been seeing humpbacks passing quite far away in the straight.
  • The pigeon guillemot nest that we have been observing closely (near our back porch) has at least one chick! We carefully peeked into the crevice and caught a glimpse of a tiny puff of black downy feathers. We are excited to be able to watch their activity so closely from our window as they are very secretive with their movements typically.
  • The remaining male elephant seal has been venturing to other parts of the island as his moult is finishing up. He has been finding some creative places to wiggle over rocks into shallow pools heated by water spilling over sun warmed rocks as the tides rise.
  • We heard a surfbird’s call today while out near the jetty- it’s a very shrill sound, just like the second recording here.
