The Red-breasted Goose (Branta ruficollis) is a brightly marked, endangered species of goose in the genus Branta from Eurasia. The Red-breasted Goose is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. It was considered a Vulnerable species by the IUCN. Over 80% of the population roost during the winter at just five sites, with nearby feeding areas threatened by changes in land use. In addition, there has been a strong decline in numbers in the last decades. As it is not clear to what extent the known population fluctuates in this species – as in other Arctic geese – and given the worsening outlook for the species as a whole, the Red-breasted Goose was uplisted from a species of Least Concern to Endangered status in the 2007 IUCN Red List.
