Despite its superficial similarity to the brant goose, genetic analysis has shown it is an eastern derivative of the cackling goose lineage. The barnacle goose was first classified taxonomically by Johann Matthäus Bechstein in 1803. "Branta" is a Latinised form of Old Norse "Brandgás", "burnt (black) goose" and the specific epithet is from the Ancient Greek "leukos" "white", and "opsis" "faced".

Bar-headed goose Bar-headed goose The bar-headed goose ("Anser indicus") is a goose that breeds in Central Asia in colonies of thousands near mountain lakes and winters in South Asia, as far south as peninsular India. It lays three to eight eggs at a time in a ground nest. The grey goose genus "Anser" has no other member indigenous to the Indian region, nor any at all to the Ethiopian, Australian, or Neotropical regions. Ludwig Reichenbach placed the bar-headed goose in the monotypic genus "Eulabeia" in 1852, though John Boyd's taxonomy treats both "Eulabeia" and the genus "Chen" as subgenera of "Anser". The
