The Atlas records for these ground-nesting herbivores represent known introductions. The now feral population of geese established at the Rockefeller Wildlife Refuge in Vermilion and Cameron parishes was stocked from large birds that were transplanted from Minnesota in the early 1960's.

Most Mallards nest well north or west of Louisiana. Although Mallards of naturally wild ancestry are suspected of breeding in the state, most of the Atlas records probably represent domestic or feral birds (released birds that have "gone wild"). The ducklings of these ground-nesting herbivores feed on aquatic insects.

These ground-nesting omnivores are very common in the Coastal Marsh Region in Louisiana, with small numbers breeding northward in extensive marsh or rice fields, as shown in the Atlas records from West Carroll and Morehouse parishes. Mottled Ducks are on the Audubon WatchList for North America.
