A Large Flock of Snow Geese

Driving across the Skagit Flats in winter I frequently encounter snow geese. I have posted about snow geese before: white-russians-in-northwest-washington. On my way to Whidbey Island late this morning I encountered the largest snow geese flock I have seen south of Bay View. They had been out on the tide flats during the snow, but grass fields are their preferred wintering ground.
