Overview
Canada Geese are a non-native species introduced to Britain from North America in the 17th century. Now one of the most familiar large waterbirds in the UK, they're resident at Marshside and the Marine Lake. Bold, noisy and adaptable, they're often in large groups and readily mix with other geese. Despite not being native, they provide an opportunity for close observation of goose behaviour and are good for beginner birdwatchers.
