Sea otter back

One tour boat today in main channel. Eagles all over the island. 1 sea otter off boat ramp eating sea urchin. Canada geese are claiming parts of the island. Bird of prey is feeding at night on some of the gulls. Perhaps a owl but I have not seen it yet. The leftovers from the kills are scattered around the island every morning.

There were a lot of eco tourism boats passing through the ecological reserve today. An outrigger canoeist paddled through the main channel in the mid morning and again in the early afternoon.

Tomorrow is my last day as the Ecoguardian. Mara and Kai are returning for a few months. I have enjoyed being back on this wonderful island for the past 17 days, learning on the edge where the land meets the sea meets sky. Race Rocks is a unique place that couldn’t exist without the work of Pearson students, staff, faculty, alumni and volunteers.

Here are some sights from around the island today:

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.

The groups of steller and california sea lions around the main island and on Middle Rocks have all increased in number. There were two noteworthy sea lions today. In the afternoon, I noticed a lone steller sea lion near the end of the jetty. It had a white and red flasher (fishing lure) hooked to its mouth. Unfortunately, this is a sight that is occasionally seen here. Just last week there was another steller sea lion with a pink and yellow flasher. That sea lion (branded O-19) has not been spotted since. The flashers could have had a fish hooked on the end, which was eaten by the sea lion, or the lure could have appeared to the sea lion to be a fish. The sea lion this afternoon, left the jetty when a large boat went by. A few minutes later, it appeared on Middle Rock where a group of about thirty sea lions were hauled out. I will keep an eye on this sea lion. If it stays around for a few days, it could be a candidate for a rescue from the Marine Mammal Rescue Centre.

When I spotted the sea lion with the flasher haul out on Middle Rock, I noticed a steller sea lion branded 975R. The R means it was branded at Rogue Reef, in Oregon. This animal has been seen here before. See Ecoguardian Anne Stewart’s post from April 6, 2015. The steller was branded as a pup in 2011.

There were about twenty-five eco tour boats that passed through the Ecological Reserve today, some of them repeats. They appeared to be viewing the hauled out sea lions, harbour seals and the floating in the kelp sea otter.

See the photos below for sights and happenings from today:

While I have only provided the conditions for today, I did step onto the Rock just after noon yesterday. It’s great to be back, having spent the whole winter and the first few weeks of spring here. I will be here for the next two and a half weeks, 100 days shorter than my last stint.

I feel very fortunate to be a part of the amazing team of Pearson students, alumni, staff, volunteers, donors and researchers who keep this Ecological Reserve going.

I spent yesterday afternoon and evening reacquainting myself with this wonderful place, practicing how to avoid disturbing the young gulls, who blend in well with the rocks as they like to hide beside the paths and in plants.

This weekend, there have been a lot of boats (pleasure craft and eco tour boats) taking advantage of the nice weather. The only visitor to the island, other than me, was Greg, who drove me out here from Pearson and brought back Mara and Kai.

In the previous log post, on August 13, a branded sea lion with an attached flasher (fishing lure) was mentioned. The steller sea lion is branded O-19. Bryan Wright, the Marine Mammal Biometrician/Project Leader at the Oregon Department of Fish and Wildlife, gave us an update on the history of the stellar sea lion:

He was captured and branded by us (ODFW, along with WDFW) at Bonneville Dam on the Columbia River on February 2, 2012.  We don’t know his exact age but he was probably 5-7 years old at the time of capture, making him 12-15 now.  He then wasn’t seen again until July 21, 2016, at Tatoosh Island off the tip of the Olympic Peninsula in Washington.  He was then next seen back at Bonneville Dam from August-November, 2019.

Bryan also passed along an interesting article that was just published called “California Sea Lion (Zalophus Californianus) Monitoring In The Lower Columbia River, 1997–2018” (Brown et al 2020). Click here to read the abstract of the article.

Otter Observations, Seagull Takeover!

Today’s Weather:

  • Sky Clear, blue (very foggy in morning and evening)
  • Visibility 10+ NM (less than 1 during fog)
  • Wind 10-20 knots W
  • Sea state: calm, slightly rippled

Marine Traffic/Visitors:

  • Yesterday Greg visited to drop off some supplies, as well as on Thursday
  • Less than 10 whale watching boats per day recently
  • Minimal pleasure craft activity and the regular stream of fishing vessels, and larger ships

Ecological Observations: 

Due to amount of nesting birds and chicks, we’ve been going outside only when necessary as our presence seems to bother them quite a bit. Some of the windows facing the action have been getting, ahm… ‘fogged’ despite our efforts to collect rain water and scrub them when we can!

  • One of the two elephant seals molting has left the island, and the last pieces of skin are falling off in big dry pieces for the one remaining.
  • Seagull season is getting a bit violent: there are many deceased and dismembered seagull chicks around the island. We don’t usually see it happen, but we think that they are being killed by other adult seagulls protecting their territory and chicks.
  • While walking over the rocky area near the jetty to recover a significant amount of plastic that floated in, we noticed some pigeon guillemot eggs hidden in a rocky crevice! This is the first time that we have spotted a confirmed nest, although we had suspicions as we have been seeing them with fish and waiting for us to leave (before they carry it into their nest).
  • We found a pigeon guillemot near the jetty under camera five- it appeared to have been eaten by a bird of prey or perhaps an otter. It had been partially plucked of its feathers and eviscerated.
  • We’ve been noticing more harbour seal pups! We’re not sure if this is due to there being a increase in the total pups around, or we are seeing them closer than usual due to the low tides this week. We spot the pups with their mothers taking shelter from heavy currents in the more sheltered area between us and rosedale rock.
  • Yesterday we noticed that there were quite a few dead seagull chicks dragged underneath a diesel tank waiting for removal near the jetty/crane shed. We looked under the walkway where we often see the river otter duck through the rocks, and there were quite a few there as well. This explains the cacophony we sometimes hear at night!
  • We were contacted by an eco-tourism company who shared with us that they had spotted “ollie” the sea otter holding the body of a river otter. It sounds like he has been noted as particularly territorial before, so this is not a surprise, although this is the first time we have heard this during our time on Race Rocks.

We’ve been saving the fresh water that drains from the firehoses after pumping from Second Nature’s tank, and using it to fill the pressure washer tank. We can use this to mist the panels and scrub them by hand to remove the seagull waste that builds up so quickly this time of year. Every little bit of sun counts!

Busy Critters

Today’s Weather Conditions: 

  • Sky overcast
  • Visibility 15+ NM
  • Wind 0-5 knots SW
  • Sea state: calm

Visitors/Marine Traffic: 

  • Yesterday Greg and Jake came from the college to deliver some equipment
  • An influx of boats today. We have been seeing 3-5 whale watching boats everyday. They have been coming very close to the elephant seals when they are in the shallow jetty water and also very close to the kelp patch where “ollie” the sea otter likes to rest. Quite a few pleasure crafts as well, and two kayakers this afternoon who explored the intertidal at low tide.

Ecological Observations: 

  • The 4 goslings are now over 1 week old. The parent geese seem much more responsible than the previous, and the goslings seem to be doing okay.
  • There have been nearly no sea lions in the reserve this week.
  • On Friday evening we spotted a sea otter swimming in the kelp around the jetty.
  • Two whimbrels stopped in for a visit on Thursday evening
