BARNACLE GOOSE The Barnacle Goose is an attractive member of the Branta genus of the goose family. It shares its largely black-and-white plumage with other family members like Canada and Brent Geese. Back in the day, Barnacle Geese and other Branta geese were deemed as all belonging to the same species. It was also believed then that they spent the first stage of their life as Barnacles clinging onto rocks. Malmö enjoys the migration spectacle of the thousands of Barnacle Geese that pass over during the spring from Holland on their way to the high Arctic. The word ‘enjoys’ has to be used with a certain amount of trepidation as some of the wild birds stop to breed with the city’s burgeoning feral population. Herein lies the problem. With up to 50,000 birds in the city calling and defecating where they stand, it is easy to see why some of the locals detest them. The Barnacle Goose is now among the city’s most common breeding birds. This feral population is a fairly recent phenomenon, with the colonies first establishing during the 1980s.
