Brant are seasonally abundant in parts of Atlantic Canada during spring and fall migration periods as they travel between wintering grounds in the south and breeding grounds in the Arctic. In Atlantic Canada, surveys to monitor the abundance and distribution of this species are not typically conducted. However, due to their large size and flocking tendency, they are highly visible and easily counted during other surveys and by members of the public. As such, incidental sightings of Brant flocks may be used to monitor general patterns of abundance, distribution, and timing of migrations in the Maritimes. A database of incidental sighting records was created by first extracting observations of Brant from existing CWS Atlantic aerial survey datasets. This dataset is supplemented with additional data sources such as provincial data and social media (e.g., eBird and iNaturalist). The data span from 1925 to 2024, containing more than 12000 records. The minimum spatial resolution of each entry is based on Coastal Block IDs, though some records have more precise coordinates.
