Feral

Definition

Living in the wild and reproducing without human management, but descended from domesticated or captive-bred ancestors. Feral populations differ from truly wild populations in their genetic origin and often in behavior, morphology, or ecological impact. The term distinguishes escaped or released organisms from indigenous wild stock and from ongoing domesticates.

Etymology

From Latin fera, 'wild beast,' via Middle French feral and fauve.

Example

Colonies of feral honey bees (Apis mellifera) descended from managed hives have become established in many regions, competing with native pollinators and sometimes hybridizing with local wild subspecies.

Synonyms

• feralized
• gone wild

Related Terms

• domesticated
• introduced species
• Invasive
• wild type
• feralization
• biological control escape

Usage Notes

Contrasts with 'wild' (indigenous, never domesticated) and 'domesticated' (under active human management). Sometimes used loosely for any free-living population, but specialists reserve it for lineages with documented domestic ancestry. In entomology, commonly applied to escaped biological control agents (e.g., feral parasitoid wasps) and escaped pollinators or silk moths. Does not imply invasiveness—feral populations may be benign or ecologically disruptive depending on context.
