Found anywhere with water, including city parks, backyard creeks, and various wetland habitats. Often in flocks, and frequently mixes with other duck species. Females can be tricky to distinguish from other duck species, but they are all darker-bodied than Mallard. White wingbars on the edges of the blue wing patch are also bolder on Mallard. There are frequent hybrids. Any bird with extensive white in the tail or curled feathers above the tail has some Mallard genes.
