Canada Geese were introduced into Europe, the first arriving in Britain during 1665 into St James’s Park, London. Since then, numbers have undergone an accelerating rate of increase and their distribution can be found all across Britain. Love them or hate them, we must live with Canada Geese. Although, when they occur in large numbers, they may constitute a nuisance to some as they can cause damage to agricultural crops, by grazing and trampling, fouling with droppings and causing damage to wildlife habitat.

Initiated and funded by the RSPCA Science Group, this joint study aimed to learn more about the moult migration movements of Canada Geese moulting on Windermere, Cumbria. Over the course of 4 years, over 1000 Canada geese were rounded up and marked with leg rings. In 2019, we took over the administration of this study and although ringing as now been completed, the results from this study are soon to be analysed and published.
