Abstract: Wildlife on and in the surroundings of an aerodrome pose a potential hazard for flight safety. Canada geese (Branta canadensis) represent a substantial risk for aircraft, due to their size and flocking behaviour. A group of 51 Canada geese were caught and neck-collared at two moult sites in the vicinity of Paris-Le Bourget airport. Six individuals were also GPS tagged. Bird movements were monitored between July 2019 and June 2021. The flight patterns and phenology, as well as the dispersion pattern of these birds, were investigated. Flights represented only about 1 per cent of geese daily activity. Geese spent most of their time on the ground in a 10km radius area around the capture sites. More than half of the flights outside the capture sites took place at the end of the day, between 6pm and 8pm. These flights were performed on average at less than 50m above the ground, and only less than 1 per cent of them crossed Paris-Le Bourget airport airspace. The finding of this study can be of interest to airport operators and regulators for the development of a management plan to help to reduce birdstrike risk to aircraft.
