In the early 1980s, there were no Trumpeter Swans in Minnesota. To reintroduce them into the state, 21 birds were released near the Tamarac National Wildlife Refuge in 1987. There were several more releases in the late 1980s and throughout the 1990s.
In 2004, there were an estimated 2,000 Trumpeter Swans in Minnesota. That number grew to 17,021 in 2015, over 30,000 in 2020. The 2022 Minnesota Breeding Trumpeter Swan Survey, conducted by the Minnesota DNR, estimated the statewide population at 51,860 swans.
