One of the UKs grey geese though does tend to be browner than the other species. It breeds in north Scandinavia, north Russia and north Asia, and visits Britain in small numbers in autumn and winter. Numbers have declined in recent years, possibly due to increased human disturbance, changes in agriculture and direct persecution. It breeds in dense coniferous forests, birch scrub or wet, low-lying tundra. In the winter it feeds on wet grassland, roosts on lakes or flooded fields nearby.
