Mallard Drake: Mallards can live in almost any wetland habitat whether natural or artificial. Look for them on lakes, ponds, marshes, rivers and coastal habitats. They enjoy city and suburban parks, as well as residential backyards.

After a brief internet search I hope I have correctly identified the 2 fossils in the middle of the photo as Honeycomb Favosites Coral. They had washed up on the Lake Huron shoreline. They are from an extinct order of coral called tabulate corals which also formed colourful reefs and lived in warm, shallow waters. They have been smoothed and polished by sand and water.
