Weekly Census

The wind varied in velocity and direction throughout the day.  Fog settled in overnight as the wind blew between 15-25 knots from the southwest.  In the daylight hours, the wind blew from the south and west between 7-32 knots.  The barometer dropped slightly from 1008 hPa to 1004 hPa.  It was overcast with patches of sun and rain throughout the day. The temperature reached a high of 12.8oC at noon.

There was one whale watching boat seen in the reserve, in the mid afternoon.

I saw humpback whales (Megaptera novaeangliae) twice today, both times from the kitchen window.  The whales were surfacing just south of Great Race Rocks, within the boundaries of the Ecological Reserve.  At 9:30am, I saw two humpbacks blow, surface and dive westward.  At 3:20pm, I saw one humpback surface and dive eastward.  I am not positive if they were different whales, so I counted them as two in the census.

Two branded steller sea lions were seen seen today.  76Y was a pup in 2002 when it was branded in St. George Reef, California.  443Y was branded in 2013, when it was a pup at Rogue Reef, Oregon.

Here are the results of the weekly census:

Humpback Whale: 2
Steller Sea Lion: 244
California Sea Lion: 216
Harbour Seal: 39

Weekly Census of Race Rock’s Megafauna

The wind blew about 10 knots from the north.  The barometer rose overnight from 1009 hPa to 1013 hPa as the sun set at 16:29, beginning to drop in the evening.  The sea was rippled.  The sky was mostly overcast with some breaks of sun and occasional light rain showers.  It hasn’t rained here during the day (possibly at all) in about two weeks.

There was one whale watching boat seen in the reserve today.  It spent a lot of time near the southern side Race Rocks, where the whale watching boats don’t usually go. Three small grey inflatable military boats sped around the edge of the reserve at 15:00, coming within less than a hundred meters of the islands.  After their circuit, they headed back towards the navy base.

Here are the results of the weekly census:

Steller Sea Lion: 263
California Sea Lion: 208
Harbour Seal: 7
Northern Elephant Seal: 5
Bald Eagle: 4 (2 adults, 2 juveniles)
Canada Goose: 9
Harlequin Duck: 3
Double Crested Cormorant: 44
Pelagic Cormorant: 147
Black Oystercatcher: 10
Gull: 396
Black Turnstone: 20
Rock Sandpiper: 3
Surfbird: 17
Fox Sparrow: 1

As always, there were variations in the numbers seen since last week.  There were fewer harbour seals.  I checked them throughout the day, the most I was able to see at one time were seven, scattered around the many small islands.  The tide was fairly high during the daylight hours, which tends to not be good hauling out conditions for the seals.  There were more smaller birds seen this week.  It was easier to spot smaller birds this week because of the lower wind speed.  I had a tough time distinguishing the rock sandpipers amongst the surfbirds.  While they look very similar, the surfbirds are a bit larger and have shorter bills.  See if you can tell the difference in the photos below.

 

A Mighty Wind’s a Blowin’ for Census Day

The barometer dropped all last night from 1015 hPa to 1002 hPa this morning, before it began to climb again towards 1008 by the end of the day.   The wind started from the northeast, but then switched to blow strongly from the southwest from mid morning onwards. The gusts reached 47 knots in the evening.

There were two whale watching boats seen in the reserve.

Once the fog lifted, the census was a bit easier to do. Then the wind blew up and most of the birds hunkered down on the leeward side of the island. I wasn’t able to positively identify all of the individual species of gull. Next week, I will strive to get an accurate breakdown of the number of glaucous-winged, thayer’s, california, western and heerman’s. There are a lot fewer gulls compared to last week, only 14% of the 3224 that were on the reserve last Thursday.

See the photos below for some of the noteworthy species and sights seen during today’s census.

Here are the results of the census:

Steller Sea Lion: 211

California Sea Lion: 404

A steller sea lion with the brand “966R.” The “R” signifies that it was branded in Rogue Reef, Oregon. I will add more information when I find out.  [Updated information from Pat Gearin with the NOAA: The Steller was branded as a pup at Rogue Reef, Oregon in July 2011.  It is a male and so far we have 9 resights from this individual, all from BC.  In 2011, he was sighted at Pachena Point once, and in 2012 he was sighted at Carmanah 8 times.]

A branded california sea lion with the brand “U596.” The “U” or “C” depending on which way you look at it, means that the sea lion was captured in the Columbia River Area. It was branded in Astoria, Oregon.  [Updated information from Matthew Tennis: U596 was branded on August 15, 2014 in Astoria. At that time he weighed ~193 kg. He was seen in Astoria for a few days following the branding and again in the middle of October. This is the first resight for this animal outside of Astoria. They have high site fidelity and being a relatively young animal, it is very possible he will be seen at Race Rocks for years to come.]

Real Rain

There was measurable rain last night and this morning for the first time in a long time, followed by fairly thick fog. Eventually the fog burned off and the northeast wind chased it out of the Strait. Although it is now blue sky above, it seems to be the donut hole with clouds all around, so expect more showers and outflow winds. The barometer started climbing out of the hole early this morning and kept climbing most of the day, until leveling off late afternoon. On the satellite, it looks like the first pineapple express of the season and we are in the lee of the Olympic Mountains.

Rain, sunshine and fog, with god-rays for good measure.

There was only one whale watching boat today ‘Gold Wing’, one recreational boat and a couple of commercial charter vessels.

The second of three first year Marine Science classes came for a field trip today. Their quest was similar to yesterday’s class; to make first-hand observations and enter their notes and drawings into their field journals and to add to their species lists. I added consumption of warm fruit crumble, with very Canadian maple syrup to their to do list and the students seemed to enjoy the whole process.

The California Sea Lions seem to be disturbed by the rain and spent the night making a lot of noise. In the morning most of them moved into the water when the rain started again. Could it be that there hasn’t been much rain where they have been? So far we have brands from the Channel Islands, Rogue Reef in southern Oregon and the Columbia River in northern Oregon.

We had some new arrivals today in the form of a flock of very tired Surfbirds. They slept most of the day. Their breeding grounds are in the mountains of the Yukon and in Alaska and they winter here on the coast.

Surfbirds arrived today and rested.

There were also a couple of Western Sandpipers flitting about today. They breed in western Alaska and are heading south, just passing through here. If they are looking for biofilm, Race Rocks is covered in it, even though with its’ high current and rocky substrate, it is the opposite of a mudflat, it has such a massive concentration of life that there is food for eveyone. I saw more Black Oystercatchers today than I have in a couple of weeks. They are one of my favourite birds.

Black Oystercatchers are very jazzy birds. They have the most spartan nests imaginable. The adult pairs are quite site fidel.

I am preparing to attend an international workshop on ocean literacy, followed by the European Marine Science Educator’s Conference. Also trying to trouble-shoot the Davis wind direction data, which is reading greater than 360o. All the normal, potential problems seem fine, so it is still a mystery. Regular tasks like making power, making water, testing the seawater, taking photos of branded animals and generally fighting entropy, continue. Here is another photo for Garry of sea lions in the foreground and shipping in the not too distant background.

Rhinocerous auklet

Clear in the morning and overcast a bit in the afternoon. Low winds getting up to 10 knots in the evening. Barometric pressure dropping during the day. Strong wind warning in effect for tomorrow and forecasted fog.

7 whale watching boats

5 recreational fishing boats

The was a Rhinocerous auklet (Cerorhinca monocerata) in the water off the north side of the island. Haven’t seen many of these this summer. There was also a small flock of Surfbirds (Aphriza virgata) on the SW end of the main island just after sunset.

Worked on the tank shed a bit today. Talked with Environment Canada and Coast Guard regarding maintenance issues. Everything is now in order.

Back for Spring

It is good to be back on Race Rocks after a winter on the road in Mexico. It seems I am not the only one returning as the Pigeon Guillemots have been returning over the last few days as well. I am planning a special entry focused on them in the next week so stay tuned!

These birds usually eat invertebrates so this picture of one eating Sea Lettuce (ulva lactuca) a bit unusual.

Black Oystercatchers (over 100–a record for RR)  and gulls with westerly swells.

Green Winged Teals

The SGBs (Small Grey Birds). Not only do they all look very similar but they hide their beaks! There was a mix of Black Turnstone, Surfbirds and Rock Sandpipers in the NE bay.

On January 7 an 8th there was a W wind 30-35 knots.  The Green Winged Teals returned to the island with slightly higher numbers than last time, they spent their time in the pools on the NE side and picking through the mud with their beaks.  I  have not seen any Pelicans in about a week and there have not been any Canada Geese here for about two weeks.  Karen Benzel from International Bird Rescue contacted us recently to report that Pelican R36 that was seen here in November has been taken in for rehabilitation at Wild Arc in Metchosin.

Things have been fairly quite lately regarding birds and mammals here, though one of the eco-tour boats reported seeing a Sea Otter (Enhydra lutris) in a kelp bed on Monday! The percussive blasts from Rocky Point military testing range scared off most of the Sea Lions last Thursday and only a few have returned in the last couple days. A large pod of orca passed through and near the reserve on Tuesday. Thanks to Suna, Doris and Ishmael for the census.
