Barnacle goose: The barnacle goose is a migratory goose with a black-and-white head, native to Arctic breeding regions and European wintering grounds. Its striking plumage and migration distinguish this Branta species.
Mitochondrial DNA: Mitochondrial DNA is genetic material found in mitochondria and often used to study maternal ancestry. Genetic comparisons help clarify relationships among closely related Branta species.
Goose management: Goose management comprises measures used to address population growth, habitat impacts, and conflicts with people. Large resident Canada goose populations have prompted management programs.
