Lesser Snow Goose Migration GPS Tracking
Welcome to the great migration of the lesser snow goose (Chen caerulescens caerulescens). While over 10 million geese make the trek, you will see the movement of only a few radio-tagged lesser snow geese in the map below. These birds were tagged with cellular GPS tracking collars in July 2019 at the Banks Island Migratory Bird Sanctuary: the most northern point marked on the map below. They travel from Arctic breeding grounds in Alaska and Canada to wintering grounds in southern United States and northern Mexico.
Update – The Final Collar
The GPS collars were originally designed to function for 2 years. To our surprise, one bird is still transmitting a GPS location into the third year of this project. We will continue to show the bird's tracked location as long as we are receiving data.
A Bit of History
In the 1970s, this species was considered at risk. Since then, the population has increased by nearly 1,200 percent! The species is now considered overabundant and is causing damage to their summer breeding grounds, which is home to dozens of other bird species as well as crop lands along their annual migration routes. The main food sources during migration are from crops of corn, peas, and cereal grains.
The Government of Canada has identified the reduction of lesser snow goose numbers as a priority for conservation efforts.
As a concerned conservationist in Alberta, you can spread the word! The overpopulation of the lesser snow goose is a great opportunity to truly put our conservation efforts to work.
Note: Collars missing from the map have not submitted location data within the listed time frames. GPS data submission is subject to cellular tower proximity, battery life, or other unknown causes.
Support from the Environment and Climate Change Canada department made this project possible.

Alberta Conservation Association (ACA) provides radio tagged geese GPS-located information for general audience consumption and is not intended for specific activities or purposes. For those using the GPS information for specific activities or personal purposes, ACA has implemented a 24-hour delay on the provided GPS data.
The GPS tracking devices provide information via cellular towers. Therefore, if the radio tagged geese are not in range of cellular towers, GPS tracking data will not be available.
