This Canada goose pair have been devouring John's grass. It's amazing how much they eat. You notice how they stand back to back? It's for defense. They can cover nearly 360° so that predators are quickly seen. They don't seem to have a nest because they spend all their time eating and not brooding eggs. Be sure to read the book below if you are interested in the natural history of Canada geese. It was invaluable for my observations.
