Mallard
The mallard is among the most widespread species of wild duck. It lives among the lakes and marshes of Europe, Asia, and North America. Mallards eat invertebrates and plants on the water's surface or in fields. A shallow nest is lined with down and built at the end of ponds or in open grassland. The nest normally contains from eight to ten eggs. Wild mallards are beneficial because they eat mosquito larvae.
