Dodecaceria concharum: Coraline-fringed tubeworm–The Race Rocks Taxonomy

Below is a  close up view of a colony of Dodecaceria concharum emerging from Lithothamnion. On the left is a cryptically coloured sculpin that takes advantage of the background for blending in. See the complete picture below.

This video was taken by PB on the remote camera at Race Rocks on July 17, 2007.Of special note here is the nictitating membrane which shows as the bird doses off to sleep.

On June 4th 2006, I received two e-mails at the same time: The one from Pam Birley from England included pictures of an unidentified shorebird, taken at some distance from the remote camera. The other from David Alison from the Rocky Point Bird Observatory had the following observation:

Hi Garry,
On Thursday 31st, Rocky Point recorded its first Long-billed Curlew over the lower field right at the banding shack (#299 on our checklist!). This morning (Sunday 4th), two of us were lucky enough to observe via spotting scope no doubt the same (or perhaps a different?!) Long-billed Curlew on the North Race Rock. Not sure if you have recorded that species from Race Rocks before?
I’ll check your website’s video cams later to see if we can capture it on film (as we last saw it flying towards Great Race Rock)!
Cheers,
David Allinson

It turns out that the pictures were of another type of curlew, the whimbrel, not a long-billed curlew. It was from the second set of pictures that I made this slide show above.

After David saw the pictures, he wrote “Interesting…perhaps we jumped to the conclusion on our distant bird as the bird in the photo is clearly a whimbrel, not a Long-billed Curlew..? This has been a good spring for both species locally. Or perhaps indeed both species were present.…I know it may seem like coincidence, but I am still strongly inclined to “keep” our sighting from Sunday at 1115 on North Rock as a Long-billed Curlew (it was a large shorebird, big bill, and cinnamon wash which is not consistent with whimbrel ). As I mentioned, there have been good numbers of whimbrel  this spring (as many as 33 were at the Victoria Golf Course one day in May!), and both species are known to associate.
Whimbrel are annual at Rocky Point both in spring and fall migration, but particularly in “fall” (July to September, and November in 2015), and they presumably occur on Race Rocks regularly. However, there are less than a dozen accepted Long-billed Curlew records for Victoria, but 1-2 birds are reliably reported on the south island every spring during the last few years (the Victoria Golf Course in Oak Bay seems to be a best spot along with whimbrel and marbled godwits congregating on the green at the 5th tee).

Thanks to these two observers for their assistance in recording this species for Race Rocks.Further Reference:

Terebratalia transversa: the transverse lamp shell– The Race Rocks Taxonomy

The only time we have seen one of these was in 1999 when several grab samples were taken by researchers using a dredge in water over 30 metre depth.

Lampshells belong to the  Brachiopods. They resemble bivalves but are unrelated . A good example of convergent evolution. Lampshells appear commonly in the fossil record ,  and although, both bivalves and lampshells have two shells, however they are not related. Bivalves have shells that are symmetrical mirror images of each other, whereas with lamphells, the two shells and the internal structures are very different.

The video shows the typical feeding pattern of the dunlin, probing the debris at the bottom of tidepools for crustaceans, insects and larvae.

raisablkturnand-1In this picture taken by Raisa Mirza in December 2011,  you can compare the Dunlin in it’s winter plumage with the Black turnstone. They often feed together in the winter months around the tidepools and over  the rain-saturated lawn areas.

Phalacrocorax penicilatu: Brandt’s Cormorant–The Race Rocks Taxonomy

Brant's cormorants

Brant’s cormorants:  Phalacrocorax penicilatu -photo by Alex Fletcher

This cormorant is numerous in the winter, with much of the British Columbia population present at that time, as it is a relatively rare bird. In 1987 a survey that reported 3 nests was done on 15 July by Wayne Campbell and was reported in: Campbell, R.W., and Preston, M. 1988. British Columbia nest records scheme. Thirty-first and thirty-second annual report 1986-1987. British Columbia Naturalist 26:12-13.

Here are the links to the Christmas Bird Counts.

In 2014 and for several years previous, there have been no cormorants nesting at Race Rocks.  The only still-thriving colonies are at Mandarte Island.

This is a  Blue-listed species in BC. This list includes species not immediately threatened, but of concern because of characteristics that make them particularly sensitive to human activities or natural events.
