Suspicious Seagull Suppers, A Busy Few Days

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!

Ship Traffic in the Strait of Juan de Fuca

If you go to the website for tracking  marine vessels  (http://vtslite.siitech.com/VTSLite/AView.aspx ) you can see the vessels currently in the waters around Race Rocks. Today I checked and at one time noted the four vessels indicated on the chart below.

I took a picture from Camera1 of the tanker Pacific Endeavor just south of Race Rocks :

With the projected increase in traffic of tankers in the Strait of Juan de Fuca, the risk of an oil spill doubles.See this recent government report on Risk Analysis. 

Ebb and Flow

We have had, and will be hosting, many students this week. Laura has been doing her marine biology review classes with the students. It is great to have company!

Though we don’t get a lot of flotsam and jetsam here, on occasion something unusual washes in. A few days ago I found a tupperware container in the intertidal zone. Much to my surprise, upon opening it I found a dead tiger-striped hamster in a ziplock bag. I can only assume a grieving child gave their beloved pet a burial at sea. I intended to give the wee creature a proper burial to add to the island’s biomass, but I left it alone for a few minutes outside and a raven flew off with the little morsel. The circle of life continues…

I will have the students do a thorough animal census this weekend. Meanwhile I have started painting the kitchen and planting a small garden.

Fisher’s discarded neck-ring on Northern Sea Lion

Aside

rmneckringoct102009More evidence of injuries showing up on the sea lions. Ryan recorded them with images on his Flickr site:

Also see this link to the log pages with injured marine mammals.

Another neck ring that will painfully kill this animal. This sea lion may be relatively lucky, the position of the ring may cause a chronic ear infection that will kill it more quickly than the typical starvation/asphyxiation deaths that neck rings can cause.rmneckscar

Balloon pollution !

Good Morning
WEATHER: Sky Overcast –Vis 7 Miles — Moderate Rain — Wind NNE 18 Knots –Sea 1 foot chop.
posted by Angus Matthews at 7:24 AMGood Evening
TEMPERATURE: Max. 5.0c >Min 4.2c >Reset 4.8c > Rain 6.0
MARINE LIFE: A day of some confusion as a total reorganisation of the Centre Rock occurred when a large male Elephant Seal returned to the rock and everyone had to trade places. Some confusion for the geese as well with the arrival of a third pair starting a turf war. Only 1 mature and 1 immature Bald Eagle seen today about 16:45.
HUMAN INTERACTION: One dive charter boat with 4 divers aboard in the MPA during the morning and 2 eco-tour boats through in the afternoon. One rental boat 14K-37805 with two people aboard set up to fish just west of the engine room but left when hailed and waved off. A TRIDENT submarine was observed steaming (or reacting) west out of the strait for places unknown under the oceans. One other unusual environmental impact today; as a consequence of a political protest at the BC legislature some 12 nautical miles from Race Rocks. Three blue balloons with the Hospital Employee’s Union logo floated through the MPA carried on the ebb tide and a NNE breeze. Unfortunate pollution.
I was joined by my wife Sandy and our friends Cathy Denny and David Anderson who are staying overnight as deputy assistant guest Eco-guardians. This resulted in a great dinner of Red Snapper. (NOT taken from the MPA!)
