In most years since 1997 we have been able to contribute to the Christmas Bird Count for the Sooke/Victoria area. This website contains all the past records: This year, Garry Fletcher was picked up with the station boat by the … Continue reading
The first gentle sou’east weather pattern with clouds and rain occurred in the last few days. The rain is most welcome to wash away a summers worth of gull and pinniped excrement. This island can be smelled from a kilometer away!
At the edge of the world…
Surrounded by ankle-biters!
About 2/3s of the sea lions have left since the weather change. We are down to around 140 animals, perhaps 75 are Stellers down from the 175 of 10 days ago. Californians make up the remainder down from 225. Quite a few juveniles have showed up in the last week.
More birds are showing up. In the last few days several Harlequin ducks and a few dozen cormorants returned to dot the shoreline with the oystercatchers. Flocks of Bonaparte gulls feed on minnows in the eddies, forced to the surface from the deeper water by murres and rhinoceros auklets. Killdeers are spending the nights here. I hear them when I shut down the generator at night. Close to 30 sparrows are flitting about, and yesterday a few eagles and ravens were hunting and scavenging. Late developing gull chicks are on the menu. The flock of turnstones forages in the sea lion haulout ignored by the sea lions.
Tour boats are becoming less frequent and sport fishermen are waning too… yesterday for example a pod of orca passed with only 2 boats watching them rather than 8-10.

Since the gale on Saturday night, about 75 Steller and 150 Californian sea lions have been hanging out under my window in the shelter of the house. It is hard to describe just how loud and smelly it is. I wish you could witness it for yourself! Well you can at: http://www.racerocks.com/racerock/video1frame.htm
Here are a few pictures. The Steller bulls (Eumetopias jubatus) are particularly impressive. Some of them weigh in at 1000 kgs.

Sea Lions are extremely social and appear boisterous and argumentative. Smaller individuals will always move for the bigger ones, though they roar, growl and hiss in protest. Clashes are very frequent but damage is rare. Most of the contact actually involves just the whiskers (vibrissae), though nips to the skin do happen. Usually a smaller one will snap back in defence then lurch away across the backs of the sleeping neighbours who lazily complain til the commotion stops and they drift back to sleep. 30 seconds later it happens again… all day long and most of the night too!

Sealions on the South rocks: Panorama by Ryan Murphy
Orca’: 6, ‘A pod of around 6-8 orcas passed W to E through Rosedale Reef this morning..
California Sea Lion’, 1
Orca: 8, ‘At 2025hrs PDT a pod of orcas was spotted heading E to W through Race Passage against the flood current. Seven eco-tour boats were in pursuit.’, ‘Adam’, ’20:28:24 ,
230 glaucous-winged gulls were counted on the island today, which puts us at around 115 nests, down from 150 last year at this time.’, ‘adam’, ’12:09:54 ,
Ryan Murphy took this shot from the top of the tower. Race Rocks is an important winter roosting place for several species of gull. He did this image in high resolution so that it can be magnified considerably: This is the distribution of them on the south-west corner of Great Race Rocks, the main island of the Ecological Reserve. The Science house, (originally the assistant light-keeper residence) is shown on the right.
Gulls at Race Rocks , November 11, 2009–photo by Ryan Murphy, Ecoguardian.
A visual census using the remote camera 5 focused on Middle Island.
The following panorama was taken of the “middle islands” at Race Rocks from 6 images taken consecutively with a small overlap and then spliced together with a “Photostitch” program which is usually available with the software for an electronic camera.
Educational Application: When we build up a set of these pictures, students can do mathematical projects by going on the camera and getting a live count and then running various statistical comparisons on these archived images. Just click on the image below for a version that is large enough to enable counting and identification.
