The Canada Goose is a large bird that is native to North America, but was introduced into the UK in the 17th century and has now established feral populations in various parts of the country.

It has a distinctive black head and neck, white cheek patches, and a brownish-grey body.

The Canada Goose can sometimes cause problems in urban areas, where large numbers of geese can create a mess and damage crops.

In these cases, management techniques such as egg addling and habitat modification may be used to control populations.
