The mallard duck is the common ancestor of many breeds of domestic duck. First domesticated in Southeast Asia, domestic ducks have long maintained a connection with wild mallards given their ability to interbreed and produce fertile offspring.
The mallard is highly adaptable to new environments and thus is considered invasive in parts of its range. Their adaptable diet and flexibility with nesting sites and habitat needs means they can adapt easily to a variety of human altered environments.
