Aechmophorus occidentalis: Western grebe- The Race Rocks Taxonomy

Western grebes overwinter here on Southern Vancouver Island in the protected coastal bays. Three pairs were seen in Pedder bay throughout January and February of 2006. They feed on fish at night following trails of bioluminescence as the fish swim through the water. ( see reference below)

It may surprize some to know that this is one of the few prairie pond birds which do not migrate South during the winter, but instead migrate West over the Rocks mountains to the Coastal Bays of Vancouver Island.

The Western Grebe is classified by the Alberta Government as a Species at Risk.

Research on Foraging indicating a night-feeding pattern is presented in the research of James Clowater, See this link to his thesis.

Domain Eukarya
Kingdom Animalia
