Birds of different feather flock together - genetic structure of Taiga Bean Goose in Central Scandinavia
During their flightless summer moult, Taiga Bean Geese Anser fabalis fabalis gather at communal moulting sites. Individuals from the Nord-Trøndelag breeding area in Norway have been observed to join with local individuals on moulting sites in Vilhelmina Municipality, Sweden. These two groups show di...

During their flightless summer moult, Taiga Bean Geese Anser fabalis fabalis gather at communal moulting sites.
