When you live in Michigan, and you see your first Robin, it normally means that Spring is on it's way. Apparently, not all Robins migrate. They will stay in an area as long as there is a food source. They will continue to move south as their food source is depleted. There have been flocks of them in my area for several days. This one was in the marsh area where there is still open water.
