Snow geese

I live on Lulu Island in the Fraser River delta of BC, Canada. Each year, 70,000 snow geese fly here from Wrangel Island, north of Siberia, to spend the winter with us. They feed on bullrushes, grasses, leftover crops in the farmers fields. They stick together in very large flocks, cheek to jowl.

When they take flight en masse, it's an unforgettable spectacle -- their black wing tips and honking voices transform them into a shimmering cloud of life.
