This is the first observation and photos we have of cackling geese at  Race Rocks. Ecoguardian Raisa Mirza  took this photo on October 22, 2010. These geese migrate south through the area at this time of year. This is a newly recognized and smaller species of the Canada Goose. Recent work on mitochondrial DNA genetic differences found the four smallest forms to be very different. These four races are now recognized as a full species: the Cackling Goose. It breeds farther northward and westward than does the Canada Goose..Fall migration includes staging on the upper Alaska Peninsula for several weeks, then a trans-oceanic flight to Oregon and California.

This tag will bring up other examples of observations of this species at Race Rocks.

bryozoa

Photo by Dr. Anita Brinckmann-Voss

This species is classified in The Lophophorate Phyla of British Columbia: Entoprocts,Bryozoans,Phoronids and Brachiopods by Aaron Baldwin School of Fisheries, U. of Alaska.

We see this bryozoan frequently in the lower intertidal while diving at Race Rocks in 8-12 metres of water.

“Each colony is hte result of budding or cloning from the original individual itself having developed from a planktonic larvae that settled … In the case of this species, the process is programmed as a spiral growth pattern. From ” Marine Life of the Pacific Northwest, Andy Lamb and Bernard P. Hanby ,2005,
