Yesterday, Al Eisner mentioned a Snow Goose at Seaport Centre in Redwood City. After admiring the continuing Harris's Sparrow on the Public Trail circling Facebook - the subject of Al's post - I biked over to look for the rare goose. It was exactly where described, at Chesapeake and Galveston Drives, standing out among scores of Canada Geese. But I thought it was a Ross's Goose. The question is: is this a hybrid, a Ross's or a Snow Goose? Inquiring minds, including Al's, want to know.
