We used telemetry data from 55 trumpeter swans in the Rocky Mountain Population captured in summer and winter in the western United States to understand their migratory movements and use of habitats. This dataset includes telemetry data collected between October and March from 35 swans (5 swans captured in Oregon and 14 swans captured by Wyoming Wetlands Society are not included due to data sharing restrictions, and 1 swan captured in Montana is not included because the only data are in July and August). These data do not include telemetry data collected between April and September because those data could be used to infer nesting locations. We used these data to analyze distances traveled by swans, characteristics of swans migrating between Canada and the United States, migratory connectivity, and habitat use of swans.
