NamingBased on a molecular phylogenetic study published in 2014, some authorities place this species together with the Orinoco goose in the resurrected genus ''Oressochen''.
ReproductionIt nests on the ground in a bare scrape near water, laying 6–10 eggs. It is territorial in the breeding season, but otherwise forms small flocks.
