Suspicious Seagull Suppers, A Busy Few Days

Posted on by

Weather: 

  • Sky partially overcast, some light showers throughout the week
  • Visibility 15 miles this morning, consistent throughout the day, some heavy fog a few days ago
  • Wind 10-15 knots W
  • Water ranging from calm to choppy with waves up to 1.5m over the last few days

Boats/Visitors: 

  • There’s been a lot going on over the past few days! Our apologies for the lapse in updates.
  • On Monday, after a few weeks of planning, the Marine Mammal Rescue team from the Vancouver Aquarium came out to RR with support from DFO, to attempt disentanglement of the troubled sea lions we’ve been spotting. Stay tuned for an in-depth post detailing the days events with many photos and videos! 
  • We have been having minor trouble with the water supply/storage for our house here, but with a little investigation and some extra water deliveries it seems to be changing for the better!
  • With water deliveries, there have been a handful of guests, notably including a guest speaker visiting the college to address students. It’s always nice to see some friendly faces!

Ecological: 

  • The sea lions continue to haul out in larger numbers, but it seems to be tapering off. Our electric fence lines are holding better as they learn (through trial and error) not to push through them.
  • Young seagulls are naive to the danger sea lions pose – we have observed juvenile birds being trampled to death by a sea lion simply moving quickly to a different area of the rock. The birds who learn quickly live to fish another day…
  • Over our time on Race Rocks we have been finding plastic/general garbage across the island compressed into a similar size and shape. After observing a seagull regurgitate a condiment packet (ex: rectangular, fast food style ketchup package), we believe this plastic to be consumed by seagulls on land or at sea, and then carried back to Race Rocks when the birds come to feed their young or rest. Regurgitating the foreign waste, perhaps to feed their offspring or out of discomfort, they deposit this human trash here.
  • Here are some picture showing the plastic/garbage described above:
  • On the note of seagull diet, here are some picture of sea life remains found around RR which would seem to be left overs (and examples of what they should be eating) –  talk about sea food from the source!

More Sea Lion Injuries Due to Fishing

Posted on by

Weather: 

  • Sky partly cloudy, some periods of fog
  • Visibility 1-15 miles intermittently
  • Wind 20-30 knots W – NW
  • Water rough, whitecaps, swells around 1m

Boats/Visitors: 

  • No visitors today, but on Sunday Corey drove us back to Race Rocks with some more water as we were having troubles getting our boat to start.
  • There have not been many whale watching boats but when they are here they often get quite close to the sea lions (within 10m). We can tell when there is a boat present in the reserve by the increase in “barking” and distressed sounds that the sea lions make.

Ecological: 

  • Over the weekend a sea lion was spotted with some fishing line wrapped around its neck. We believe that it could be the same one spotted last year. As it grows it will likely die due to slow suffocation caused by the line. Unfortunately it’s virtually impossible to have someone come to tranquilize and remove the line as the sea lions move on before they can get here. However, if we see it again we will report the injury.
  • Today we found a large fishing hook which must have come loose off of a sea lion. We’ve previously observed sea lions trying to remove fishing hooks from their skin by rubbing against the jetty.
  • There are quite a few sea lions all over the island now. We have been delaying our water sample that we normally take from the jetty to avoid having to chase them off, since when they are startled they climb over each other or rush off of the side of the jetty where the water isn’t very deep. The few that have come near the house don’t seem to be moving around much, just resting and getting away from the crowds.
  • With the return of the sea lions we’ve been getting bitten by little black fleas that we also saw in late spring. They were not a problem while the sea lions were not here, so we’re wondering if the two are connected.
  • Many of the young seagulls have left or are flying very well. A few of the latest hatched are still here, but the mothers are starting to leave them to fend for themselves.
  • We have been spotting the odd young elephant seal hauling out for a few hours before continuing on.
  • We’ve been noticing eagle feathers and dead adult seagulls around the island. Oddly, we haven’t seen the eagles hunting.

Maintenance: 

  • We’ve been needing to do daily fence repairs on the electric fence at the back of the island as the sea lions have been trampling it and breaking the wire and insulators that hold the wire on the posts. Hopefully with some persistence on our part they will learn to leave it alone.
  • Today we also set up the electric fence that runs between our house and the jetty/north island to prevent them from coming up around the infrastructure. They are stinky and destructive if you let them get too close!
  • We are still picking up sharp bits of tin and shingles/tar paper/ misc. litter from around the island. Some of it is from the roofs being redone recently, but a lot of it is older and becoming exposed now that the grasses are dormant for the summer.  Today we filled two buckets in an hour or two of scavenging.

Wacky Warm Weather

Posted on by

Weather: 

  • Sky blue with some clouds. Thick fog early this morning.
  • Visibility 15+ miles
  • Wind 20-30 knots W
  • Over the past two days we had wind blowing less than 5 knots NE, which meant very warm, still conditions.

Boats/Visitors: 

  • On the 27th Guy and Corey delivered more water
  • Not too many eco-tourism boats despite the beautiful weather
  • One of our friends is visiting for a few days. Great to see a new face out here!

Maintenance: 

  • Corey and Guy also helped haul away an entire boat full of trash/recycling/unneeded items that we had gathered for removal earlier in the season.
  • We spent a handful of hours over the past few days collecting approx. 50 lbs of smaller bits of shingles and tar paper from the roofing project as well as other trash that has been exposed now that the tall grass is dry and pressed down from the animals.
  • Yesterday we washed the windows with a big brush and squeegee to get rid of all of the seagull poop that had blown onto them- much better!
  • We noticed some bricks protecting a cable by the crane shed were missing, but upon further investigation it turned out that they were simply knocked out of place and buried in the tall grass. We were able to unearth them and get everything back in place.

Continued Documentation of Vessel Activity

Posted on by

Over the past few days we have been keeping an eye on eco-tourism vessels, and have been documenting their presence and their proximity to wildlife. The somewhat isolated nature of Race Rocks, minimal to no presence of regulating authority, and many other factors lead to a high risk of animals and the delicate marine environment being disturbed and potentially exploited.

While the distance of a vessel from wildlife is important, another considerable disturbance may be vibration and noise. Eco-tourism vessels fighting against the current to get the best viewing angle of resting animals easily vibrates a glass of water in our concrete foundation dwelling, over 100m from the waters edge. Another factor to consider is the volume of traffic. Items shaking in our home is normal, and we often hear boats coming before we see them. Perhaps a handful of boats conducting themselves responsibly would not be a problem, but on some days we see approximately 35+ eco-tourism boats alone. This does not include private vessels.

The below video is from July 31st, 2019 at 1413hr. It shows two zodiacs coming close to a pod of orcas within the reserve. The orcas were visible for over 15 minutes before this video was taken, and conversation on VHF channel 68 and 79 indicated that all boats in the area knew of their presence. Based on what we observed, it seemed as though the boats did not accidentally drift into place. Visible in the background is North Rock, video taken from the jetty.

We were unable to previously post it due to its size, but discovered uploading to YouTube and embedding to be a great solution.

As mentioned in the last blog post, the hauled out sea lions continue to provide an opportunity to observe how closely boats approach the wildlife. Here are three more videos of boats approaching the resting sea lions, all filmed within the last few days:

Additionally, here are some photos of miscellaneous vessels taken within the last 5 days or so:

This boat is interesting, it comes through often (see matching hull numbers) with different passengers but the same operator.

Another interesting boat coming in close for a look:

 

Weather: 

  • Sky clear
  • Visibility 15+ miles
  • Wind 10 knots W
  • Water flat to rippled

Boats/Visitors: 

  • No visitors over the last few days.

Ecological: 

On the day the roofers were here a pod of orcas came through the reserve and I misplaced this photo, here it is now.

  • Census as follows:
  • 250 sea lions
  • 200-300 seagulls
  • 6 Canadian geese
  • Ruddy Turnstones and migrating birds come and go frequently

Rooftop Renovations

Posted on by

Weather: 

  • Sky partially overcast
  • Visibility 15+ miles
  • Wind 10-15 knots SW
  • Water rippled

Boats/Visitors: 

  • Lots of things going on over the last days!
  • A work crew came out and replaced the roof on the boat house, tank shed, and crane control room.
  • The old shingles and tar paper are heavy! Removing them is messy work – but headway has been made. I think one more load taken away in Second Nature would deal with the leftovers.
  • Today Mara returned, catching a ride with a water delivery.

Ecological: 

  • Sea lions are taking over! Their numbers continue increasing.
  • I’ve seen young seagulls land in the shallow water by the jetty, only to have a sea lion come up under it and eat it whole.
  • The adult seagulls have started to chase and peck at their own young. I think this is probably to encourage their independence.

Soon, The Electric Fence?

Posted on by

Weather: 

  • Sky partially overcast
  • Visibility 10+ miles
  • Wind 10 knots SW
  • Water rippled

Boats/Visitors: 

  • No visitors over the last few days.
  • The weekend was quiet, and Monday has been the same.

Ecological: 

  • The sea lions continue their advances on the island! I think that the electric fence will soon need to be deployed.
  • Seagulls continue to develop, see in the picture a family of three young (grouped) and one adult (foreground). The shorter chick hatched roughly 5 days later than its siblings and struggles to keep up in growth. Hopefully there’s lots more growing in it’s future, we named the little one Bonsai!

A Busy Day On The Water

Posted on by

Weather: 

  • Blue skies, some clouds
  • Visibility 20+ miles
  • Wind 5-10 knots W
  • Water rippled

Boats/Visitors: 

  • Many whale watching vessels today. With the increasing number of sea lions hauling out on great race rock, these eco tourism boats contrast sharply (in relatively close quarters) against the wildlife looking to rest on the rocks.
  • The high traffic in conjunction with the sea lions provides a great opportunity to display the proximity of these vessels from the wildlife. See the videos and photos below:

 

Ecological: 

  • An increasing number of sea lions hauling out on all rocks.
  • Young seagulls can be seen strengthening their wings, flapping and hopping 3 feet in the air. They play games with sticks and other debris, aggressively keeping the objects from their siblings looks to be practice for protecting precious food in the future.
  • Mentioned in a previous post, I was able to get a picture of the sea lion with the identifying gash in its side.

Census:

  • 350 – 400 seagulls
  • 24 harbour seals
  • 68 sea lions
  • A handful of oystercatchers and cormorants (roughly 5-10 of each)

The Sea Lions Are Coming

Posted on by

Weather:

  • Sky blue, partly cloudy
  • Visibility 13+ miles
  • Wind 10-20 knots SW
  • Water calm

Visitors/Boats: 

  • Not much boat traffic these past few days. It has been quite foggy and windy (40+ knots of wind)
  • Today Greg is bringing some water for the main tank. He is also bringing a volunteer from the college who will stay overnight.
  • Tomorrow morning we will have a group tour the island

Maintenance:

  • Yesterday Alex Fletcher came to take measurements from the batteries that supply the entire island. We have been having some problems with the technology but the batteries are looking good and healthy.
  • Our Canadian flag is still down, as the flag pole was too heavy for us to lower alone. We will try to enlist the help of Greg and the volunteer today and get things back in order!

Ecological: 

  • The sea lions are starting to haul out onto Great Race Rock more and more. We will need to put up the electric fence soon to prevent them from coming right up to our backdoor as their local population increases. We are waiting for the elephant seals to leave, as the fence would prevent them from moving freely onto the jetty.
  • There are now two younger elephant seals who arrived a couple of days ago. One of them went back to a favourite spot of one of this years spring pups, so we wonder if it is the same one.

Working on the energy systems

Posted on by

Weather

  • Visibility: 15 miles
  • Wind: 25-35 knts W
  • Sky: Partly Cloudy
  • Water: 1-2 meter waves with white caps

Boats/Visitors/Sightings

  • Kyle brought in a team of PTTP technicians to the island to help finish our new energy system wiring and to optimize our solar array for the greatest efficiency. Additionally, we also carried some of the older lead-acid batteries from the battery room to the tank room, from where they will be loaded on to a boat for the main island.
  • Kyle was also able to repair the Boston Whaler onsite – looks like the issue was corrosion on the contacts to the battery and the switch. He was able to sand the corrosion away and the electronics jumped to life!

Marine Mammals

  • The sea lions have completely disappeared over the last 2-3 days. Can’t see a single one around now
  • Elephant seal counts are at 2 females and 4 males – 3 of the males seemed to be all huddled up next to the student house, possibly to escape the wind.
