The Canada Goose was originally a native of North America. A few individuals manage to reach the UK naturally each year. However, the vast majority of the population dates from introductions. Historical records show that this was likely to have begun in the early 17th century, when a group of geese were presented to King Louis XIII in Paris. In the UK the first recorded introduction was in the late 17th century, when a group of Canada Geese were introduced into the Royal wildfowl collection in St James’s Park. From these small beginnings, it is estimated that the current UK breeding population is 62,000 pairs and the wintering population is around 190,000 birds.
The Canada goose has become a common bird of UK lakes, gravel pits and urban parks. They usually form monogamous pairings which stay together until one bird dies. They can lay between 2-9 eggs per pair per year (average five) and it is not uncommon on our local lake to have 10 to 15 young every summer. In the UK there are not many things that will take even a half grown Canada goose and so it is easy to see how their numbers prospered over the years. Indeed, in some places measures have had to be taken to limit their success and prevent them becoming a pest. Interestingly, the UK population unlike its American counterpart tends to be a resident species with very limited migration.
